▼ DNA replication initiates from any given origin at
most once per cell cycle to ensure perfect duplication of the
hereditary material. DNA re-replication occurs when an origin
initiates more than once. This can lead to DNA damage, gene
amplification, and genomic rearrangements, all hallmarks of cancer.
Whereas it is difficult to study re-replication in cancer cells,
the fungus fly Sciara coprophila is a tractable alternative where
re-replication occurs in the DNA puffs of giant polytene
chromosomes in larval salivary glands during normal development.
The DNA sequence for only one of many DNA puffs was known,
preventing identification of shared motifs. Progress has also been
thwarted by the absence of a genome sequence, necessary for
genomics approaches. In this thesis, I present the first draft of
the Sciara coprophila genome sequence, assembled using Illumina
short reads, long single-molecule reads from Pacific Biosciences
and Oxford Nanopore, and optical maps from BioNano
Genomics. Using
the Oxford Nanopore MinION, I established protocols to obtain high
quality, ultra-long reads that exceed 100 kb in some cases, which
were important in assembling multi-megabase contigs. RNA sequencing
of the transcriptomes of both sexes across the lifecycle
facilitated annotation of genes hidden in the genome sequence. High
throughput sequencing of the salivary gland genome throughout the
DNA re-replication stages identified multiple DNA puff sequences,
which were confirmed with qPCR, and in some cases mapped by
Fluorescence in situ Hybridization (FISH) to corresponding DNA
puffs. Mapping the origins where DNA re-replication begins is still
needed to locate cis-regulatory elements. Toward this goal, I have
refined the genome-wide origin mapping technique Nascent Strand
sequencing (NS-seq) by inclusion of important controls and found
that nucleosomes are phased around a subset of origins near
G-quadruplex motifs in the human genome. Moreover, I describe my
progress in developing new single-molecule, genome-wide origin
mapping techniques. Overall, this thesis presents the genome and
DNA puff sequences of Sciara coprophila as well as methods to map
the re-replication origins, thereby establishing a foundation to
unravel the mechanism of site-specific DNA
re-replication.

▼ Many species are currently threatened by the direct and indirect effects of anthropogenically driven climate change. The elevation of global temperatures and increase in variability in both temperature and precipitation pose a risk to biodiversity as species are pushed close to their thermal safety margins. Current predictions suggest a dramatic loss of species diversity and the contraction of geographical ranges of many species. Many ectothermic insects that cannot regulate their body temperature are likely to be threatened, particularly ecologically- restricted herbivorous insects that depend for on plants for food and that are often in phenological synchrony with their plant hosts. However, adaptive shifts in these species in response to host loss and climatic extremes may counter the effects of climate change to some extent. This highlights the importance of studying species-specific adaptation mechanisms including host interactions. This dissertation contributes to this overall aim by studying the genomic basis of climatic and host adaptation. I use Drosophila melanogaster as a model system at the intraspecific level, and Drosophila species from the repleta group as a model system for the comparative level. In assessing the genomic basis of host responses, I consider a much broader range of insect taxa.
This dissertation begins with a study on the use of chromosome level sequencing of D. melanogaster populations from two ends of a thermal cline. I present genomic evidence for the role of the inversion 3R Payne in capturing alleles favourable to local climatic conditions in the non-inverted form, and therefore driving adaptation to climate change. The study further elucidates the impact of climatically important chromosomal inversions in driving higher linkage disequilibrium on the non-inverted form - potentially benefiting both karyotypes.
In the second chapter, I develop a new pipeline, Orthonome, and tools for multi-species comparisons for prediction of orthologues and inparalogues with the highest accuracy and recall. Using Orthonome, I was able to identify a much greater level of conservation across Drosophilid lineages than earlier thought, amounting to nearly 33% better resolution than industry-accepted methods.
I then use Orthonome in the third chapter to compare the genomes of 58 insect species – most of which are known to be agricultural pests. Testing across eight gene families, I present evidence for genomic patterns in only four gene families (P450s, CCEs, GSTs and ABCs) as being associated with polyphagy or particular host ranges. While three of them have been reported before, I find that ABC transporters present much stronger evidence than reflected in earlier studies, with feeding behaviour as well as host tissue displaying an effect on gene gain in more voracious pest species.
Finally, in the last study, I use novel genomic data and evidence from the repleta group of drosophilids to carry out phylogenetically constrained analyses of genes potentially associated with host and thermal…

▼ Lactic acid bacteria (LAB) play a dual role in food manufacturing. While being indispensable for food fermentations and preservation, they are also involved in spoilage of foods and beverages, and some food-borne LAB are pathogens. Particularly, they became the main spoilage organisms in the cold-stored modified atmosphere packaged (MAP) foods. LAB species composition and their relative abundances depend on the nature of food products and preservation technology. However, two LAB species, Leuconostoc gelidum and Lactococcus piscium, have frequently been predominating at the end of shelf life in a variety of packaged and refrigerated foods of animal and plant origin. Besides the predominant species, spoilage LAB communities contain less abundant and slower growing species, such as Lactobacillus oligofermentans, the role of which in food spoilage is unclear. Taking into account the increased popularity of MAP technology combined with cold storage for preservation of minimally processed fresh foods, the need to obtain more information on the metabolism, genomics, ecology and interactions of psychrotrophic food-spoilage-associated LAB is clear. In this thesis a genomic approach was used to study these LAB.
In order to characterize spoilage community members, we sequenced and annotated genomes of Lc. piscium MKFS47 and Lb. oligofermentans LMG 22743T, both isolated from broiler meat, and seven strains of Le. gelidum, isolated from vegetable-based foods. The analysis of their gene contents and their comparison with gene repertoire of other close related species allowed us to predict putative factors that might facilitate their survival in their habitats and increase competitiveness in the spoilage microbial communities. No major differences in the gene contents of the vegetable and meat Le. gelidum strains were observed that would suggest niche-specificity, therefore, indicating that the absence of strain dissemination between vegetable- and meat-processing chains is a more likely factor responsible for the reported strain segregation between vegetable and meat-based products.
Lc. piscium MKFS47 was identified as an efficient producer of buttery off-odors compounds from glucose under aerobic conditions, which is in agreement with the previous inoculation studies. Time course glucose catabolism-based transcriptome profiles revealed the presence of classical carbon catabolite repression mechanism for the regulation of carbohydrate catabolism, which was relieved along with decreasing concentration of glucose. During the same time, the shift from homolactic to heterolactic fermentation mode was observed.
For Lb. oligofermentans, a pentose-preferring obligate heterofermentative LAB, the induction of efficient utilization of hexoses was confirmed indicating that it has flexible carbohydrate catabolism, which can be adjusted depending on the carbohydrate sources available in the environment. Unexpectedly, transcriptome responses of Lb. oligofermentans during growth on glucose and xylose were more alike than during…

▼ Myriad species are experiencing declining numbers worldwide, yet many details of the eco-evolutionary responses to population decline remain poorly characterized in wild species. Rapidly shrinking populations experience loss of genetic diversity and increased homozygosity from changes in the balance of genetic drift, mutation, gene flow, selection, and inbreeding. Despite good theoretical knowledge of the impact of these factors on population genetics, thorough empirical evaluations in natural populations are scarce because they demand huge field and laboratory investments. Recent development of nextgeneration sequencing technologies now permits discovery and genotyping of large numbers of genetic markers in any species. Combining genomic data with long-term demographic and pedigree data from a natural population allows us to explore fundamental questions concerning the population genetic consequences of declining population size. Here, I describe two bioinformatics methods for analyzing genomic data and apply these methods to develop substantial genomic resources for one of the longest-studied endangered species in the world, the Florida Scrub-Jay (Aphelocoma coerulescens). One method identifies sequences specific to the heterogametic sex chromosome, and another uses pedigree information to improve single nucleotide polymorphism (SNP) discovery. A population of individually banded Florida Scrub-Jays at Archbold Biological Station has been studied for more than 43 years, providing an unparalleled model for research on the
genomics of population decline. I geno- typed 3,578 individuals sampled through time at 15,416 genome-wide SNPs. To investigate the impact of regional population decline on our stable study population, I used 7,404 autosomal SNPs to calculate levels of heterozygosity and inbreeding. Decreasing immigration over time was correlated with an increasing mean inbreeding coefficient of the birth cohort, and inbreeding was correlated with higher rates of hatching failure. These results imply that despite the small and shrinking size of peripheral populations, their small but measurable genetic differentiation from the central population may give them a crucial role in maintaining genetic diversity. This study, which marks the beginning of a detailed longitudinal investigation of
genomics in a wild animal population, underscores the vital importance of maintaining gene flow among remnant populations, for the Florida Scrub-Jay specifically, and for other declining species more broadly.

▼ Growth and division are the two most important processes in plant organogenesis. Cell size results from the dynamic combination of these two processes. Hence studying cell size patterning is crucial to understand organogenesis. The Arabidopsis sepal epidermis is an ideal system to study cell size as it forms a characteristic cell size pattern ranging from cells with only one hundredth the length of the sepal (small cells) to cells with one-fifth the length of the sepal (giant cells). Small cells are produced by ordinary mitosis whereas giant cells are produced by endoreduplication. In my dissertation, I addressed how cell size patterning is generated by genetic and genomic approaches. In my first study, I discovered that the endomembrane trafficking protein SEC24A suppresses endoreduplication in an ACR4, DEK1 and LGO dependent manner. SEC24A, the first identified giant cell formation inhibitor, unraveled a hidden layer of the complicated regulatory network of cell size patterning. In my second study, I applied translating ribosome affinity purification coupled with deep sequencing (TRAP-seq) to systematically discover changes in gene expression between differently sized cells. It was discovered that the giant and small cells have very distinct translatomes, implying they are different cell types. In addition, by comparing the giant cell and another highly endoreduplicated cell type, the trichome, we discovered that although endoreduplication triggers common downstream responses, the giant cell and trichome do have distinct genomic regulation modules. Cell biology and genetics were applied and validated the high-throughput sequencing results.

▼ Cancer is caused largely by the accumulation of
somatic mutations throughout an individual's life. Recent advances
in next generation sequencing (NGS) enable measurement of somatic
mutations in a cohort of samples. Cancer sequencing projects like
The Cancer Genome Atlas (TCGA) have generated numerous somatic
mutations in thousands of tumors. This thesis addresses two
challenges. The first challenge is to distinguish the handful of
driver mutations that are responsible for cancer development from
the multitude of passenger mutations that play no role in cancer in
a cohort of samples. The second challenge is to accurately identify
larger genomic variants, also known as structural variants (SV).
Although several computational methods have addressed this
challenge using NGS technologies, they are limited by the
underlying NGS data, resulting in a significant amount of SVs
remaining undetectable, particularly in highly repetitive regions
of the genome. To address the first challenge, we present two
computational methods. First, we introduce a combinatorial approach
for the problem of identifying independent and recurrent copy
number aberrations, which are gains and losses of large genomic
regions ranging in size from a few kilo-bases to whole chromosomes.
We show that our method outperforms other methods on simulated data
and performs well on TCGA cancer datasets. Second, we introduce a
statistical model to identify combinations of driver mutations that
are mutual exclusivity, a pattern expected for mutations in cancer
pathways. Our model is more sensitive in detecting combinations of
lower frequency mutations and outperforms other methods on
simulated and real data. To address the second challenge, we
present a method to identify SVs in a tumor more accurately by
utilizing a new sequencing technology from 10X
Genomics. 10X
Genomics linked-reads technology uses barcodes to label reads
originating from a longer DNA molecule, which enables the
construction of synthetic long reads. Our method uses both signals
from paired-end reads and synthetic long reads to identify SVs. We
demonstrate that our method shows high sensitivity and specificity
on simulated and real data. Together, these novel algorithms help
address the challenge of characterizing and identifying driver
mutations in cancer genomes.

▼ Identifying genetic targets of natural selection is a
primary goal of evolutionary biology research. However, molecular
signatures of natural selection must be interpreted with caution
due to the fact that neutral demographic processes can confound
signatures of selection in the genome. This thesis examines the
neutral and selective genetic history of two nearshore marine
species, the acorn barnacle, Semibalanus balanoides, and the
estuarine fish, Fundulus heteroclitus. Both species are found on
the Atlantic coast of North America, and currently occupy habitat
that was profoundly influenced by glaciation throughout the
Quarternary. In the case of S. balanoides, functional tests of
selection at a candidate gene, Mannose-6-phosphate isomerase (Mpi),
were combined with estimates of neutral demographic history using
mtDNA, microsatellite data, and whole-genome, second-generation
sequencing. The Mpi locus was also sequenced directly to test for
selection. There was evidence for functional differences at Mpi
based on genotype-dependent size phenotypes. As predicted, there
were observable effects of glaciation on populations from the
western and eastern North Atlantic, with less genetic variation
observed in the western North Atlantic populations. The Mpi locus
had a significantly elevated level of Tajima’s D, consistent with
balancing selection. Through second-generation sequencing the
largest currently available dataset for a cirripede was created,
with approximately 41x coverage of the genome of S. balanoides
recovered. In F. heteroclitus a glacial hybrid population was
sampled to study the effects of sex and mitochondrial genotype on
fitness and gene expression under hypoxia. Gene expression was
measured using microarrays and RT-PCR. A highly significant effect
of sex on hypoxia tolerance was discovered, but mitochondrial
genotype effects were not significant. Hundreds of genes were
differentially regulated by sex and hypoxia. Mitochondrial
genotypes had minimal effects on gene expression, but several
important candidate genes were discovered. The final chapter of the
dissertation used phylogenetic comparative methods to examine
endangerment status and genetic diversity in tetrapods.

▼ Recent improvements in DNA sequencing technology have
opened new paths towards understanding cancer biology and designing
personalized cancer treatments. Cancer is caused in part by somatic
mutations to the DNA of healthy cells that can be identified with
DNA sequencing technology. A major challenge in analyzing the
mutations in cancer is distinguishing the handful of driver
mutations that cause cancer from the multitude of passenger
mutations that play no role in cancer. In part to address this
challenge, consortia such as The Cancer Genome Atlas (TCGA) have
generated massive catalogues of somatic mutations in thousands of
tumors. The new wealth of mutation data has shown that identifying
driver mutations is a difficult computational problem. Many driver
mutations are rare, even in these large tumor cohorts, because
different combinations of mutations cause cancer in different
patients, even those of the same cancer (sub)type. Part of the
reason for this phenomenon is that driver mutations target key
genetic pathways that perform vital cell functions. Each pathway
consists of a set of interacting genes, and can be perturbed in
numerous ways. Therefore, we have developed computational methods
to search for combinations of driver mutations targeting pathways.
We describe several methods for identifying combinations of
putative driver mutations. We first present two methods for
identifying combinations of mutations that are mutually exclusive
in a cohort of tumors, a pattern expected for genetic pathways. We
then present an algorithm to identify significant clusters of
mutations in an interaction network. We show that these algorithms
outperform previous methods on simulated and real mutation data
from TCGA, and identify potentially novel combinations of
mutations. We also describe the Mutation Annotation and Genome
Interpretation (MAGI) web application, which displays interactive
visualizations as well as crowd-sourced and text-mined mutation
annotations in order to help prioritize likely driver mutations.
These methods contribute towards overcoming the computational
challenge of identifying driver mutations in cancer sequencing
data.

▼ In the past decade, genome sequencing costs have decreased faster than Moore's Law, resulting in a rapid increase in the volume of genomic data. This increased rate of sequencing is particularly evident in bacterial
genomics, where thousands of complete bacterial genomes are available for comparative analysis. This data has the potential to address a variety of important questions, so there is a crucial need for visualizations that scale to accommodate comparisons between hundreds of genomes at once. In parallel, advances in display hardware over the past decade have enabled rapid growth and affordability in display resolution and the development of large, high-resolution display environments. While recent research suggests that these environments present benefits to visualization designers, more research is needed to understand the design requirements for particular domain problems in order to best take advantage of these benefits. In this paper we present Bacterial Gene Neighborhood Investigation Environment, or BactoGeNIE, a new comparative gene neighborhood visualization designed to address large volumes of bacterial genome sequences by taking advantage of the special qualities of large, high-resolution displays.

▼ Uterine leiomyomata (UL), commonly known as fibroids, are one of the primary causes of morbidity in reproductive-aged women. Epidemiologic analyses, including twin studies, familial aggregation, and racial biases in disease prevalence and morbidity, suggest heritable factors influence disease risk. Previous genetic association analyses in Japanese women reported three independent loci at 10q24.33, 11p15.5, and 22q13.1; genome-wide linkage and association analyses in European women identified a genomic region encompassing FASN at 17q25.3; and, a genome-wide association study (GWAS) in African American women associated a separate region at 22q13.1 with UL. To replicate and identify additional risk variants, we assembled FibroGENE – a consortium of conventional, population-based and direct-to-consumer cohorts. Discovery-phase meta-analysis of 244,324 European women replicated the three previously associated loci in Japanese women and identified 21 novel genomic regions. Of the 24 loci in total, 17 were replicated (p < 2.08e-3) in an independent, direct-to-consumer cohort of 58,655 European women obtained through 23andMe’s Research Portal. Meta-analysis across all five cohorts of 302,979 European women revealed an additional six discovery loci. Estrogen receptor alpha (ESR1) and forkhead box protein O1 (FOXO1) were located in two candidate regions associated with UL in our analyses at 6q25.2 and 13q14.11, respectively. FOXO1 is a well-characterized tumor suppressor and hormone-regulated transcription factor that interacts with ESR1 in the estrogen-signaling pathway. We observed significant, 2.18-fold greater nuclear FOXO1 levels in UL patient samples compared to myometrial control tissue in an immunohistochemistry-based assay. Interestingly, four regions that were identified and replicated in our FibroGENE analysis were also previously associated with endometriosis – another estrogen-dependent disease affecting uterine tissue. Epidemiologic meta-analysis of multivariate-adjusted risk estimates from the Nurses’ Health Study II and Women’s Health Study revealed women with a history of endometriosis had greater odds of UL when compared to women with no previous diagnosis of endometriosis. Here, we report the identification of a previously undocumented genetic overlap between endometriosis and UL and further underscore the relationship by formal epidemiologic quantification of the comorbidity of these two highly common gynecologic diseases.

▼ High-grade serous ovarian cancer (HGSOC) is amongst the deadliest of cancers. Despite decades of research on this disease, the exact mechanisms through which this carcinoma initiates, spreads, and relapses remain unclear. I believe the main reason behind this discrepancy between importance and available knowledge roots in the fact that currently available genomics methods are not sensitive enough for accurate study of limited amount of clinical materials. To address this issue, I optimised a novel library preparation protocol called DigiPico to generate reliable next generation sequencing data from picogram quantities of DNA that can be obtained from 10-20 human cells. Moreover, I implemented DigiTitan and MutLX analysis algorithms to identify clone-specific copy number alterations and small nucleotide variations from DigiPico data. Validating MutLX algorithm using experimental and simulated data I demonstrated that DigiPico/MutLX is a uniquely sensitive, accurate, and reliable method for analysis of micro-heterogeneity in solid tumours. Next, using DigiPico, I conducted the first accurate case study of genetic micro-heterogeneity on a collection of pre-chemotherapy tumour islets and post-chemotherapy microscopic residual disease (MRD) samples from one HGSOC patient. Analysing the results using DigiTitan and MutLX, firstly, I introduced tumour heterogeneity and genetic diversity as a hallmark of HGSOC. Secondly, based on new observations from this study, I challenged a pre-existing notion that mutations in TP53 gene are responsible for the initiation of HGSOC. I proposed that mutations in the regulatory regions that adversely affect the DNA repair machinery which can lead to subsequent large-scale genomic alterations precede the loss of TP53 function in the tumorigenesis pathway of HGSOC. Thirdly, comparing the somatic mutation load of pre-chemotherapy, MRD and recurrent tumours, I demonstrated that MRD harbours the least number of somatic mutations. Thereby, I hypothesized that MRD is likely to be composed of stem cell-like tumour cells that have survived the chemotherapy therefore suggesting that MRD is likely be the recurrence precursor. Lastly, I propose experimental approaches that are required to effectively validate or nullify these hypotheses.

▼ The vast increase in the number of sequenced genomes has irreversibly changed the landscape of the biological sciences and has spawned the current post-genomic era of research. Genomic data have illuminated many adaptation and survival strategies between species and their habitats. Moreover, the analysis of prokaryotic genomic sequences is indispensible for understanding the mechanisms of bacterial pathogens and for subsequently developing effective diagnostics, drugs, and vaccines. Computational strategies for the annotation of genomic sequences are driven by the inference of function from reference genomes. However, the effectiveness of such methods is bounded by the fractional diversity of known genomes. Although metagenomes can reconcile this limitation by offering access to previously intangible organisms, harnessing metagenomic data comes with its own collection of challenges. Since the sequenced environmental fragments of metagenomes do not equate to discrete and fully intact genomes, this prevents the conventional establishment of orthologous relationships that are required for functional inference. Furthermore, the current surge in metagenomic data sets requires the development of compression strategies that can effectively accommodate large data sets that are comprised of multiple sequences and a greater proportion of auxiliary data, such as sequence headers. While modern hardware can provide vast amounts of inexpensive storage for biological databases, the compression of nucleotide sequence data is still of paramount importance in order to facilitate fast search and retrieval operations through a reduction in disk traffic. To address the issues of inference and orthology a novel protocol was developed for the prediction of functional interactions that supports data sources that lack information about orthologous relationships. To address the issue of database inundation, a compression protocol was designed that can differentiate between sequence data and auxiliary data, thereby offering reconciliation between sequence specific and general-purpose compression strategies. By resolving these and other challenges, it becomes possible to extend the potential utility of the emerging field of metagenomics.

▼ Using computational techniques to identify orthology and operon structure, it is possible to find functional interactions between genes, which, together, define the genetic interactome. These large networks contain information about the relationships between phenotypes in organisms as genes responsible for related abilities are often co-regulated and reasserting of these genes can be detected in the operon structure. However, these networks are too large to analyse by hand In order to practically analyse the networks, a computational tool, gisql, was developed and, using this tool, the connectivity patterns in the genetic interactome can be analysed to understand high-level organisation of the genome and to narrow the list of candidate genes for wet lab analysis. The many strains of Escherichia coli are interesting subjects as there are many sequenced strains and they show highly variable pathogenic abilities. Analysis shows that the pathogenic genes have a strong tendency to connect to genes ubiquitous in the E. coli pan-genome. The Rhizobiales, including Sinorhizobium meliloti and Ochrobactrum anthropi, are multi-chromosomal eukaryote-associated bacteria and a significant history of horizontal transfer. Regions of the pSymB megaplasmid of S. meliloti which cannot be deleted via transposon-targeted homologous recombination were shown to be significantly more connected to the main chromosome. Targets for functional complementation of deletions in pSymB in S. meliloti using genes from O. anthropi were identified and unusual connectivity patterns of orthologs were identified. Finally, a putative cytokinin receptor in the Rhizobiaceæ, likely involved in symbiosis with plant hosts, was identified. Thanks to the flexibility of gisql, these analyses were straight-forward and fast to develop.

▼ The wild bezoar Capra aegagrus was brought under human control c. 8,000 BC, leading to the domestic goat Capra hircus. This livestock species remains in use 10,000 years later, and is of particular importance to communities in marginal and developing regions. Despite this long and significant shared history, our knowledge of the process of goat domestication is poor and reliant on modern populations. Using genomic data derived from over 80 ancient Capra remains from southwest Asia and Europe, the patterns of genetic diversity which characterize domestic goat through time are described. Neolithic goat populations appear to share a common ancestor, supporting a single domestication process. However, strong regional differentiation and direct tests of admixture indicate localized gene flow from the wild, contributing to goat genetic diversity in both ancient and modern populations and suggesting a domestication process featuring substantial interaction with diverse wild groups. A significant genetic turnover following the Neolithic time period is observed, most strikingly in the mitochondrial gene pool but also with nuclear genome evidence, supporting a homogenization of southwest Asian goat populations. A FST outlier scan identified several regions strongly differentiated in Neolithic goat populations, including regions close or overlapping the pigmentation genes KIT and KITLG and providing evidence for the early selection by farmers for prefered phenotypes. Genomic data from 14 historic Capra samples provides context to the genus, and suggests gene flow between domestic goat other Capra species. In addition, an Epipaleolithic genome from Direkli Cave, southern Turkey, is shown to have high affinity with the Caucasian Tur, suggesting divergent populations of Capra exist in the wild that have yet to be described. Finally, genomic data from a further 26 samples are suggestive of additional complexity in early goat herding, but indicate the geographic regions which must be studied to address unresolved questions regarding the history of domestic goat.

▼ The realization of precision medicine demands new therapies to probe an increasingly diverse set of molecular targets. Unfortunately, existing drug development paradigms narrowly focus on single targets and are ill-equipped to efficiently discover collections of compounds that could address the need for individualized treatments. This challenge necessitates the development of new methods for systematically characterizing how chemicals act on cells. The completion of a comprehensive genetic interaction network in Saccharomyces cerevisiae presents a unique opportunity to develop new strategies for discovering new molecular probes. Genetic interactions have been used successfully to characterize the mode-of-action of compounds. However, to date, these methods have not been scaled to enable cost-effective screens of large compound libraries, which limits their practical use in a drug discovery context. This dissertation will describe my development of computational tools for integrating chemical-genetic and genetic interactions in S. cerevisiae to characterize compounds’ mode-of-action. With our experimental collaborators, we scaled this approach to generate and interpret chemical-genetic interaction profiles for more than 10,000 compounds. To facilitate broad use of these data and methods, I built a web portal, called MOSAIC, for visualization and analysis of our chemical genetic profiles. I also describe an application of this chemical genomics technology to discover new therapeutic leads for a rare human disease, called facioscapulohumeral muscular dystrophy (FSHD). I developed a cross-species approach that combines a murine phenotypic assay with yeast chemical-genetic profiling to characterize the mechanism of compounds protective against toxicity associated with this disease and discover new leads that target this mechanism. Finally, my dissertation extends beyond the study of single chemical-genetic perturbations to address the question of how pairwise combinations of genetic perturbations are affected across diverse chemical environments. We screened ~30,000 double mutants across 14 chemical stresses and characterized the extent to which genetic interactions are dependent on the chemical stress. We suggest a strategy for efficient selection of environments and genes that can be applied to study condition-dependent genetic interactions in other systems.

▼ Somatic Mutations in Primary Sjögren’s Syndrome Aleksandra Ivovic Despite decades of research and many insightful findings, a complete understanding of the pathogenesis of autoimmune diseases continues to elude us. In this thesis, I explore the hypothesis that somatic mutations may underpin the development and progression of autoimmune disease, specifically primary Sjögren’s syndrome (PSS). PSS is a chronic, systemic autoimmune disease characterized by dysfunction of salivary and lacrimal glands, which is mediated by immune cell infiltration into these tissues. As cells age and divide, they accumulate mutations and structural changes in DNA. These somatic mutations are often inconsequential but sometimes result in cell death, cancerous transformation, or other phenotypes. To describe the somatic mutational landscape of relevant cell types in PSS and investigate whether somatic mutations may have a role in the pathogenesis of this disease, we performed targeted and whole genome sequencing of glandular epithelial cells and tissue-infiltrating T and B lymphocytes from biopsies of minor salivary glands from PSS patients and controls. The results illustrate the mutational trends and clonal dynamics present in immune cells and glandular epithelial cells, suggesting ways in which somatic mutations in key cell types may be affecting disease pathogenesis. To complement the genomic studies and interrogate the lymphocyte cell types present in the salivary glands, I also a performed single cell transcriptome analysis of tissue-infiltrating immune cells. Based on the results of this transcriptomic investigation, I highlight new insights about the phenotypes and activation states of immune cells in the inflamed salivary glands. To our knowledge, this is the first study to perform genomic sequencing of affected tissue and tissue-infiltrating immune cells to investigate the presence of somatic mutations in autoimmune disease. Additionally, this is the first single cell genome-wide transcriptomic investigation of lymphocytes infiltrating minor salivary glands in PSS. The genomic and transcriptional findings of this research contribute novel insights to understanding the molecular origins of primary Sjögren’s syndrome.

▼ Speciation and adaptation have always been of great interest to biologists. The Hawaiian archipelago provides a natural arena for understanding adaptive radiation and speciation, and
genomics and bioinformatics offer new approaches for studying these fundamental processes. The mode of speciation should have profound impacts on the genomic architecture and patterns of reproductive isolation of new species. The Hawaiian Drosophila are a spectacular example of sequential colonization, adaptive radiation, and speciation in the islands with nearly 1,000 estimated species, of which more than 500 have been described to date.
This dissertation gives an overview of the Hawaiian Drosophila system (Chapter 1), new insights into genomes of three recently diverged species of Hawaiian picture-winged Drosophila (Chapter 2), as well as estimated gene flow patterns (Chapter 3). Additionally, I present a new approach of mapping genomic scaffolds onto chromosomes, based on NextGen sequencing from chromosomal microdissections (Chapter 4), and gene expression profiles of backcross hybrids and their parental forms (Chapter 5). Overall, obtained results were used to address such fundamental questions as the role of adaptive changes, founder effects (small effective population size in isolation), and genetic admixture during speciation.

▼ Fungi are one of the major organisms that cause allergic disease in human. A number of proteins from fungi have been found to be allergenic or possess immunostimulatory properties. Identifying and characterizing allergens from fungal genomes will help facilitate our understanding of the mechanism underlying host-pathogen interactions in allergic diseases. Currently, there is a lack of tools that allow us to rapidly and accurately predict allergens from whole genomes. In the context of whole genome annotation, allergens are rare compared to non-allergens and thus the data is considered highly skewed. In order to achieve a confident set of predicted allergens from a genome, false positive rates must be lowered. Current allergen prediction tools often produce many false positives when applied to large-scale data set such as whole genomes, and thus lower the precision. Moreover, the most accurate tools are relatively slow because they use sequence alignment to construct feature vectors for allergen classifiers. This dissertation presents computational approaches in characterizing the allergen repertoire in fungal genomes as part of the whole genome studies of Alternaria, an important allergenic/opportunistic human pathogenic fungus and necrotrophic plant parasite. In these studies, the genomes of multiple Alternaria species were characterized for the first time. Functional elements (e.g. genes, proteins) were first identified and annotated from these genomes using computational tools. Protein annotation and comparative
genomics approaches revealed the link between Alternaria genotypes and its prolific saprophytic lifestyle that provides at least a partial explanation for the development of pathological relationships between Alternaria and humans. A machine learning based tool (Allerdictor) was developed to address the neglected problem of allergen prediction in highly skewed large-scale data sets. Allerdictor exhibited high precision over high recall at fast speed and thus it is a more practical tool for large-scale allergen annotation compared with existing tools. Allerdictor was then used together with a comparative
genomics approach to survey the allergen repertoire of known allergenic fungi. We predicted a number of mold allergens that have not been experimentally characterized. These predicted allergens are potential candidates for further experimental and clinical validation. Our approaches will not only facilitate the study of allergens in the increasing number of sequenced fungal genomes but also will be useful for allergen annotation in other species and rapid prescreening of synthesized sequences for potential allergens.

▼ Thesis Ph. D. Michigan State University. Statistics 2017
This thesis is focused on developing functional data methodology with the aim of addressing problems that arise in genetic sequencing data. While significant progress has been made in identifying common genetic variants associated with diseases, these variants only explain a small proportion of heritability. Recent studies suggest that rare variants could account for this variability. With advancements in sequencing technology, large-scale sequencing studies are now being conducted to comprehensively investigate the contribution of rare variants to the genetic etiology of various diseases. Although these studies hold great potential for uncovering new disease-associated variants, the massive amount of data and complex structure of sequencing data poses great analytical challenges on association analysis. Advanced methods are needed to address these challenges and to facilitate the discovery process of new variants predisposing to various diseases. We use functional data analysis methods to capture the complexities of sequencing data.In the first chapter we investigate the importance of considering the genetic structure of sequencing data. In association studies the effect of appropriately modeling genetic structure of sequencing data on association analysis have not been well studied. We compare three statistical approaches which use different strategies to model the genetic structure. They are a burden test, a burden test that considers pairwise correlation, and a functional analysis of variance (FANOVA) test that models the gene through fitting continuous curves on an individuals genotype profile. We find some evidence in favor of treating sequencing data as a function.In the second chapter we present the definitions of some fundamental concepts in Functional Data Analysis like the mean element, covariance operator and its eigen decomposition, and Karhunen- Loeve expansion. Basis expansion and in particular Karhunen-Loeve expansion play an important role in this thesis. We briefly discuss the estimators for the mean function, the covariance operatorand their consistency. Results on the consistency of the eigenvalues and eigenfunctions of the sample covariance operator are also stated.Several times genetic data is collected on families, where the response variable or the trait of the family members can be dependent on each other. Additionally, this trait of interest can be discrete or continuous. Thus there is a need for a functional model that can handle dependent data that may be continuous or discrete. The model proposed by Muller and Stadtmuller (2005) uses the generalized estimating equations approach that can handle both continuous and discrete data. However, they assume the response variable to be univariate and the sample to be independent. There are no existing functional methods that we know of that can be directly applied to the family data. In the third chapter we develop a framework for dependent generalized functional linear models where the…

▼ My dissertation project focuses on the bacterial genus Salinispora, a marine actinomycete and an important producer of diverse secondary metabolites including anticancer and antibiotic compounds. This genus is comprised of 3 named species (S. tropica, S. arenicola, and S. pacifica) that are closely related based on the highly conserved 16S rRNA gene. Multilocus sequence analyses (MLSA) of 5 housekeeping genes revealed a well-supported concatenated tree providing strong support for the delineation of the three species and the ancestral relationship of S. arenicola to the more recently diverged sister taxa S. tropica and S. pacifica. Recently, our laboratory obtained 119 draft Salinispora genomes, which provide an unprecedented opportunity for comparative genomic analysis. Genome analyses revealed that all 119 strains share 2362 single-copy genes. This represents the Salinispora core genome, which comprises on average 46% of the gene content of each strain. Calculation of the genome-wide Average Nucleotide Identity (gANI) and Alignment Fraction (AF) provided a new perspective of Salinispora diversity and suggested that the three currently named species would be better represented by at least five additional species. The presence/absence of predicted biosynthetic gene clusters also revealed clustering patterns that were congruent with the species phylogeny, indicating that secondary metabolism represents important functional traits that help delineate species in this lineage. The genome sequences are also being used to identify shared genes that have been duplicated or occur near or within biosynthetic gene clusters (BGCs). One hypothesis is that antibiotic-resistance genes have co-evolved with antibiotic biosynthesis as a self-protection mechanism. This new approach called Target-directed genome mining identified duplicated genes from the core genome that occur near or within biosynthetic gene clusters (BGC), with the hypothesis that the products of these genes are the targets of the compounds produced by the clusters. This new method was validated with the correlation of a candidate resistance gene (fabF/B) with the orphan BGC named as PKS44 that expressed the compound thiolactomycin. This new approach may open new avenues for the discovery of novel antibiotics.

▼ Lysosomes are essential organelles required for breakdown of endocytic and biosynthetic cargo, pathogen killing and autophagy. In most cells, lysosomes are typically small punctate structures. By contrast, innate immune cells like macrophages and dendeitic cells that have been exposed to bacterial lipopolysaccharids (LPS) exhibit strikingly tubular lysosomes (TLs) and lysosome-related major histocompatility class II (MHCII) compartments (MIIC), respectively. TLs are suggested to play a role in phagosome maturation and retention of fluid-phase endocytic uptake in activated macrophages. In addition, the dendritic cell tubular MIIC (tMIIC) may be involved in antigen presentation. Since remarkably little was known about how tubular lysosomes form, I took to investigate the molecular requirements for this process in macrophages and dendritic cells and present my findings in this thesis.
Here I confirm that microtubules are necessary as a template for lysosome tabulation, along with dynein and kinesin microtubule-dependendent motors. We were first to identify molecular components necessary for lysosome tabulation; TL biogenesis required the concerted action of the Ar18b GTPasem along with its effector SKIP, a kinesin adaptor proteins for dynein and kinesin, respectively. Importantly, we observed that TLs are highly dynamic structures whereas punctate lysosomes are conspicuously more static.
I also present evidence that mTOR, a lysosomal protein kinase, is required for LPS-induced TL biogenesis and cell surface delivery of MHCII in macrophages and dendritic cells. First, I show that the MyD88-P13K-Akt-mTOR signaling pathway regulates LPS-induced lysosome tabulation. Second, I demonstrate that mTOR is required for anterograde lysosomal transport suggesting that this kinase may regulate tabulation and antigen presentation by modulating the microtubule-based motor activity of lysosomes.
Finally I present preliminary data on the properties of tubular lysosomes compare to punctate lysosomes in an effort to characterize these organelles. Among the data presented is evidence that total lysosomal volume increases significantly upon tabulation, which may have important underlying implications in antigen sampling and processing.
Overall, my work has expanded on our knowledge on our knowledge of how morphology and trafficking of lysosomes is modulated in immune cells, which may alter cell function.

▼ Genotyping by high-resolution amplicon melting is a simple method using only PCR primers and double-stranded DNA binding dyes. Heterozygous genotypes are easily assigned based on derivative melting curve shape and width. Homozygous genotypes are assigned based on Tm differences that are usually 1 °C but can be less. One potential drawback to genotyping by amplicon melting is Tm variance that can be caused by solution chemistry differences and thermal variability of PCR instruments. To address the Tm variance, internal temperature standards were created using complimentary 3'-blocked oligonucleotides which were included in each reaction. Genotyping by amplicon melting lends itself to potential multiplexing, due to only primers being used for detection. A thrombophilia panel, including the F5, F2, and the MTHFR 677 and 1298 mutations, was used as a multiplex model because of the potential additive effects of mutations at multiple loci. The first set of experiments were done using the LightCycler 1.5 and HR-1 technologies, which performed well in a blinded study of 109 samples. This assay was further improved by conversion to a mutli-sample high-resolution platform combining the LightCycler and HR-1 technologies. This new process decreased hands-on manipulation as well as overall analysis time while maintaining the same resolution.

▼ Substantial scientific investment has been directed towards understanding
factors that influence distribution patterns and animals' remarkable ability for precise
orientation and navigation, yet fundamental gaps in our knowledge remain. In my
dissertation, I applied emerging genetic technologies to conduct a top-down and
bottom-up investigation of animal movement and cue perception. First, in partnership
with Project CROOS and the California Salmon Genetic Stock Identification project,
stock-specific, marine migratory distributions of Chinook salmon (Oncorhynchus
tshawytscha) were characterized for five consecutive months (2010) over 1000 km of
coastline. A statistical model was developed to provide measures of relative stockspecific
abundance, insights into broad factors that influence migratory distribution,
and for fisheries management applications. For the second component of my
dissertation, I studied specialized olfactory cells of salmonids that are proposed to
contain nanometer-sized magnetite crystals that interact with earth strength magnetic
fields to transduce them into neural signals. The transcriptome profiles of candidate
magnetoreceptor and non-magnetic cells isolated from olfactory rosette tissue, whole
olfactory rosettes, and blood and muscle tissue were characterized from ~661 million
Illumina RNA-seq reads. A total of 1,006 differentially expressed genes were
identified in the magnetic cell sample type. Results, consistent with having identified
genes involved in magnetite crystal formation in fish, were used to develop a genetic
model of magnetic sensory perception. Finally, to provide insights into olfaction-based
homing that takes place in freshwater, the olfactory repertoire of salmonids was
inferred from the Rainbow trout (O. mykiss) genome and compared to that of 15 other
teleosts and the jawless fish, sea lamprey (Petromyzon marinus), an ancient species.
The abundance and diversity of trace amine-associated and V2R-like genes suggests
that these classes of chemoreceptors have biological importance. These findings have
relevance for resolving if salmon and other marine organisms imprint on magnetic
fields, and contribute to our understanding of how magnetic sense, olfaction, and
genetic programming are involved in migratory distributions.

▼ Choline is an essential nutrient, which functions in cellular membrane structure, neurotransmission and methyl group donation. The need for choline increases substantially during pregnancy. An Adequate Intake (AI) for choline has been established at 450mg/d for pregnant women. This thesis was focused on assessing the influence of choline intake exceeding the current AI during the third trimester of pregnancy on maternal and fetal genomic readouts in humans. A 12-week choline controlled feeding study was conducted among third trimester pregnant and nonpregnant control women. The participants were randomized to either 480mg choline/d, which is slightly above the AI, or 930mg/d. Maternal blood samples were retrieved at the study beginning (wk-0) and end (wk-12). Placental biopsies, and maternal and cord blood samples were retrieved at delivery. Epigenetic marks and transcriptomes were assessed. Genomic markers in fetal derived tissues were responsive to maternal choline intake. Specifically, the higher maternal choline intake group (930 vs 480 mg/d) had higher placental global DNA and histone methylation (P=0.02). The placental promoter DNA methylation of cortisol regulating genes corticotropin releasing hormone (CRH) (P=0.05) and glucocorticoid receptor (NR3C1) (P=0.002) were also higher among women consuming 930 vs 480 mg choline/d, which was consistent with decreased CRH gene expression (P=0.05) in the placenta and lower cortisol in cord blood (P=0.07) in the 930 mg choline/d group. Analysis of the placental transcriptome revealed that the higher maternal choline intake group had lower expression of the anti-angiogenic factor soluble fms-like tyrosine kinase-1 (sFLT1) (P=0.05), a marker that predicts preeclampsia. Similar decreases (P=0.04) were detected in maternal blood sFLT1 protein concentrations. The effect of choline on decreasing sFLT1 was confirmed in a trophoblast cell line HTR-8/SVneo. Additionally, in this cell line, suboptimal choline concentrations in the culture medium induced apoptosis, elevated oxidative stress, increased expression of angiogenic and inflammatory genes, and impaired in vitro angiogenesis. Inhibition of protein kinase C rescued the effects of low choline on angiogenesis and apoptosis indicating that choline deficiency perturbs this signaling pathway. In sum, a maternal choline intake exceeding current recommendations may beneficially program offspring stress reactivity and mitigate the production of proteins associated with preeclampsia.

▼ The genome is a dynamic system storing the genetic information responsible for the astounding diversity of life and examination of its variability is crucial to understanding the phenotypic differences between and within species. In this dissertation, I combined functional, population genetic and evolutionary genomic experiments to study three major facets of genome evolution and function in the filamentous fungal genus Aspergillus, a group with far reaching effects on human society: (1) the pathogenicity of A. fumigatus, (2) the domestication of A. oryzae and (3) the function and evolution of tandemly repeated DNA. The first portion centers on the in vitro examination of the transcriptional profile of A. fumigatus during its infective “biofilm” like state. This examination revealed widespread up-regulation of genes likely contributing to virulence (e.g. toxin-encoding gene clusters), drug resistance (e.g. transporters) and “biofilm” morphology (e.g. hydrophobins). Additionally, this facet includes a population genetics study of drug resistant and susceptible isolates of A. fumigatus from the Netherlands, where drug resistant isolates first originated. This study provided evidence of varying recombination rates between populations as well as the pattern of dissemination of antifungal resistance. The second theme also includes an examination of the genomic features differentiating A. flavus from its domesticated ecotype A. oryzae used in the production of traditional Japanese foods and beverages such as sake and soy sauce. Examination of the A. oryzae transcriptome and proteome showed several changes likely involved in domestication including reduction in toxicity, superior ability to metabolize starch and functional differences in flavor-associated genes, suggesting that, while plant and animal domestication was driven primarily by genetic alterations in developmental pathways, extensive changes of metabolism dominated microbe domestication. The third and final facet focuses on comparative genomic analyses of tandem repeats in coding and non-coding regions. Examination of coding regions revealed that the presence and copy number of tandem repeats was highly variable within and between species and overrepresented in genes with specific functions key to the fungal lifestyle. In non-coding regions, my study found little evidence supporting the longstanding, yet sparsely tested, hypothesis that tandem repeats are a universal source of rapid phenotypic variation.

▼ Tropospheric ozone (O3) is estimated to cause billions of dollars in global crop losses, but few studies have investigated the effects of elevated O3 on growth and development of C4 crop plants. Free Air Concentration Enrichment (FACE) field experiments were used to evaluate the response of diverse maize inbred and hybrid lines under elevated O3 concentrations ([O3]). Lines were scored for flowering phenology and ear architecture traits. A multi-year analysis showed inconsistent effects of O3 on development. Hybrid ear length and diameter and inbred ear length were all significantly reduced under elevated [O3] compared to ambient conditions.
Knowledge about the identity and location of agriculturally important quantitative trait loci (QTL) provides the basis for marker assisted selection in breeding programs. B73 and Mo17 Nearly Isogenic Lines (NILs) were evaluated at the FACE facility for leaf damage and QTL were mapped. In Mo17 NILs, a significant leaf damage QTL was identified on chromosome 2 at ~161 Mb (AGPv3). Results show that B73 introgressions into Mo17 in this region made NILs more susceptible. Leaf damage scores from the field in 2016 and 2017 had a strongly significant correlation (r = 0.93). Field and growth chamber results best fit is non-linear. It appears chambers can identify damage versus no-damage, but not a continuous degree of damage as seen in the field. This indicates the potential for higher-throughput phenotyping and fine mapping of early season O3 damage QTL in a controlled environment. Sensitive and tolerant NILs were identified. Co-dominant insertion/deletion markers flanking the QTL interval were designed and validated in parents and hybrids. This research supplies the resources for future experiments that combine growth chamber phenotyping and genetic fine-mapping to determine the gene(s) underlying this QTL for O3 tolerance.
Current doubled haploid (DH) inducer markers are inefficient and have a higher probability of misclassification when used for classification of tropical germplasm. Yg3-N1582, a rare dominant mutant obtained from ethyl methanesulfonate (EMS) mutagenesis, has not been previously mapped. Phenotypically, Yg3-N1582 has yellow color expression at coleoptile emergence that does not persist beyond the seedling stage, is homozygous-viable, and is non-lethal with no apparent deleterious effects. The Yg3 mutation has potential as a haploid inducer marker in exotic germplasm and small breeding programs where the use of R1-Navajo and high oil inducers is not feasible. The yg3 gene maps to 173-175Mb (AGPv3) on chromosome 5, which does not coincide with any previously characterized yg mutant. Transcriptome profiling identified GRMZM2G165521 as a candidate gene that could underlie the mutant phenotype. GRMZM2G165521 is a predicted PPR protein involved in RNA editing and is orthologous to some mutants in rice that also condition ‘yg’ phenotypes. Sequencing of GRMZM2G165521 in the Yg3 background reveals a seven base pair insertion in the first intron relative to the wild-type…

▼ Expansion of tandem cytosine-adenine-guanine (CAG)
trinucleotide repeat encoding an elongated stretch of polyglutamine
(polyQ) in the protein has been implicated in a group of
neurodegenerative diseases collectively called polyglutamine
diseases. Spinocerebellar Ataxia 17 (SCA17) is one such disease
which is caused by the expansion of a polyglutamine repeat in the
poorly conserved, structurally uncharacterized N- terminal half of
the human TATA-box binding protein (TBP). Even though TBP is well
known as a general transcription factor important for transcription
initiation at majority of eukaryotic promoters, the molecular
effects of polyQ expansion that lead to neurodegeneration in SCA17
remain elusive. We have explored the role of transcriptional
dysregulation by expanded polyglutamine stretch containing TBP in
SCA17 using a mouse neuronal cell culture based model system. Our
laboratory previously showed that mouse neuronal cells expressing a
variant of human TBP harboring an abnormally expanded polyQ tract
form intranuclear aggregates, a hallmark of polyQ diseases. In this
study, we identified genes involved in localized neuronal
translation, cytoplasmic beta-actin (Actb), eukaryotic elongation
factor2 (Eef2) and eukaryotic elongation factor 1 (Eef1alpha 1);
retrograde transport, p25 subunit of dynactin (Dctn5); survival
related gene, Vdac1 and ubiquitin related gene, ubiquitin B (Ubb)
were induced in cells with TBP containing expanded
polyQ.

▼ DNAzymes are single‐stranded
2‐deoxyoligonucleotides with catalytic activity. 10‐23 DNAzyme
being the most efficient RNA‐phosphodiesterase has been extensively
utilized in gene silencing. This study demonstrates the
effectiveness of 10‐23 DNAzyme in silencing several genes of
therapeutic interest like inducible nitric oxide synthase (iNOS),
tumor necrosis factor‐α (TNF‐α) and its receptors TNF‐R1 and
TNF‐R2, hepatitis C virus (HCV) RNA. The designed DNAzymes Dz I, II
and III cleaved murine iNOS mRNA both in vitro and in vivo. DNAzyme
target site I or translation initiation site and site II have
computer predicted (MFOLD) secondary structures but site III has no
secondary structure. All the three DNAzymes cleaved the short
transcripts generated from cloned DNA almost with equal efficiency
while cleavage efficiency is higher at site III than the other two
sites on isolated iNOS mRNA. Interestingly, at intracellular level,
DNAzyme targeted at translation initiation codon (site I) having
secondary structure cleaved iNOS mRNA, and suppressed its enzymatic
activity and protein expression more efficiently than that targeted
at sites II and III. Due to the efficient cleavage activity of the
DNAzymes as observed in murine macrophage J774 cells, the DzI and
DzIII that target site I and III were further tested in in vivo LPS
induced BALB/c mice. Consistent with the previous results in J774
cells, DzI suppressed iNOS expression much more efficiently than
DzIII. TNF‐α is a pro‐inflammatory cytokine secreted primarily by
activated macrophages. Signaling through the TNF‐α receptors,
TNF‐R1 and TNF‐R2 have been implicated in various acute and chronic
inflammatory disorders. TNFreceptor mediated activation of NF‐kB is
the key step that results in the transcriptional activation of a
number of genes which contribute to the succession of inflammatory
cascade. We have designed DNAzymes targeting mRNAs of TNF‐α and its
receptors.

▼ Genes modulating innate immunity in mammals are generally considered the first line of defense with respect to invading pathogens and therefore it has become important to characterize naturally occurring genetic variation, and subsequently determine whether this variation is likely to be benign, beneficial, or detrimental to the host. Relevant to this study, the mammalian Toll-like receptor proteins (TLR), encoded by members of the TLR gene family, have the capacity to recognize a wide variety of pathogen ligands, and mutations within these genes have been shown to influence disease susceptibility or resistance within mammalian species.
Two studies which sought to determine the frequency and distribution of naturally occurring genetic variation within the bovine and equine TLR genes revealed a large number of discrete point mutations, which were subsequently used to reconstruct haplotypes for each investigated gene across a large number of samples. Detailed analyses of haplotypes provided evidence for extensive haplotype sharing among specialized breeds, subspecies, and even divergent species. Classical and new tests of selection provided evidence for significant deviations from a strictly neutral model of molecular evolution for both cattle as well as equids, with some of the same TLR genes deviating from a strictly neutral model among divergent species. As a first step toward determining whether naturally occurring bovine TLR variation is likely to be benign, beneficial, or detrimental, we tested validated variation from bovine TLR genes capable of recognizing components of Mycobacteria for associations with Mycobacterium avium subspecies paratuberculosis (MAP) infection in dairy cattle, and found several SNPs that were nominally associated with disease status, thereby providing evidence for small-effect loci potentially influencing risk for differential susceptibility to Johne's disease.

▼ Characterizing the genome and understanding how it influences phenotypic variation is a central goal for studies on evolution. The findings of genomic research are applicable to a wide range of human endeavours, including predicting disease risk, supporting selective breeding programmes, and understanding adaptive variation in natural populations. One industry that could particularly benefit from this knowledge is Aquaculture. In recent years, aquaculture production has been increasing to offset the production limits of wild fisheries.
Genomics can be used in aquaculture to quantify variation of captive populations, reconstruct pedigrees, and improve the gains from selective breeding programs. The overall goal of this thesis research was to generate a genome-wide genotyping dataset and investigated several key traits for Australasian snapper (Chrysophrys auratus or Pagrus auratus). The findings will be used to establish one of the first
genomics-informed New Zealand aquaculture programmes and provide a better understanding of the genotype-phenotype relationships in this teleost species.
The first two chapters of this thesis provide a review of the literature and establish the background information and context for the research in subsequent data chapters. A brief overview of
genomics, fisheries and aquaculture, and the intersection of these two fields are provided in the Chapter 1. An in-depth quantitative review of 146 Quantitative Trait Loci (QTL) studies in teleost fish was then carried out in Chapter 2.
Chapter 3 provides details about the study population and the collection of genotyping data. Genotyping-By-Sequencing (GBS) was used to generate 11K Single Nucleotide Polymorphism (SNP) markers for individuals in the three generation pedigree. Together with phenotypic data the genotyping was used to reconstruct the pedigree, measure inbreeding, and estimate heritability for a range of traits. Parents were identified for 93% of the offspring and successful pedigree reconstruction indicated highly uneven contributions of each parent to the subsequent generations. The average inbreeding level did not change between generations, but significantly different inbreeding levels were observed between offspring from the two founding cohorts and as a result full and half sibling crosses within the group spawning teleost species. Heritability was estimated for a range of traits using both a pedigree relatedness matrix and a genomic relatedness matrix.
Chapter 4, uses the genotyping and phenotyping data to generate a linkage map and carry out a scan for quantitative trait loci (QTLs) associated with growth rate. The linkage map reported in this thesis is one of the highest density maps for any Sparidae species at the time of writing. It contained 24 linkage groups, which represent the 24 snapper chromosomes. Growth QTLs were found on three linkage groups and a scan of available genome data identified three candidate growth genes nearby on the linkage groups.
Chapter 5, uses the genotyping data and images collected during…
