Arabidopsis thaliana NDR1 (NON-RACE SPECIFIC DISEASE RESISTANCE-1), a plasma membrane localized protein, plays a critical role in resistance mediated by the CC-NB-LRR class of resistance (R) proteins, which includes RPS2, RPM1 and RPS5. Infection with Pseudomonas syringae pv. tomato DC3000 expressing the bacterial effector proteins AvrRpt2, AvrB and AvrPphB activate resistance through the activation of the aforementioned R proteins. Whereas the genetic requirement for NDR1 in plant disease defense signaling has been established, the global physiological role for NDR1 in Arabidopsis remained unknown. With the use of homology modeling, NDR1 was predicted to have a high degree of structural similarity to Arabidopsis LEA14, a protein implicated in abiotic stress responses, as well as to mammalian integrins, well characterized proteins involved in adhesion and signaling. This structural homology led to the examination of a physiological role for NDR1 in preventing fluid loss and maintaining the plasma membrane-cell wall continuum. Results demonstrated a substantial alteration in pathogen-induced electrolyte leakage in ndr1-1 mutant plants. As an extension of these analyses, using a combination of genetic and cell biology-based approaches, a role was identified for NDR1 in mediating plasma membrane-cell wall (PM-CW) adhesions through a specific protein motif. With the establishment of a distinct physiological role in PM-CW adhesion for NDR1 and the identification of a compromised PAMP-triggered immune response in ndr1-1, the focus shifted to the integration of NDR1 in early resistance signaling including pathogen perception, PAMP-triggered immunity (PTI) and effector delivery, recognition and signaling. To this end, the PAMP-specific flg22- and elf26-dependent signaling mechanisms were analyzed to elucidate the breadth of NDR1 function in PTI. Mechanisms identified included a role for NDR1 in the regulation of stomatal closure in response to the PAMP flg22 and the hormone abscisic acid as well as a reduction in MAPK3/6 expression after both flg22 and elf26 exposure. Furthermore, the loss of NDR1 alters the type-three secretion system mediated delivery of the P. syringae effector AvrRpt2 to the cell interior. The structural similarities of NDR1 to LEA14, an abiotic stress protein, coupled with the identification of roles for NDR1 in maintaining PM-CW adhesion and regulation of stomata led to the examination of potential abiotic stress related functions for NDR1. By monitoring leaf relative water content as well as electrolyte leakage under severe drought conditions, NDR1 was shown to be required for drought tolerance in Arabidopsis. Further analysis revealed that NDR1 mediated drought tolerance is an ABA-dependent process and the over-expression of the NDR1 protein provides increased stress tolerance in Arabidopsis. Taken together, these data indicate not only a broad role for NDR1 in defense signaling through both PAMP and effector mediated pathways, but also in…

Thesis Ph. D. Michigan State University. Plant Breeding, Genetics and Biotechnology - Horticulture 2013.

The demands on agricultural lands from a growing world population will rise at the same time that climate change is predicted to increase the abiotic stresses (e.g. drought, heat-waves, frosts and salinity) that decrease crop yield today. Efforts to increase crop abiotic stress tolerance are ongoing, including via transgenic approaches. However, unlike past transgenes, abiotic stress tolerance genes function through indirect alterations to regulatory, signaling and metabolic pathways, increasing the possibility of complex secondary effects. Concerns have been raised that such genes could alter crop persistence and ferality and, through gene flow, the invasiveness and ecological range of recipient interfertile wild or weedy relatives. These possible ecological risks are influenced by fitness effects conferred by the transgene. Despite the link between competitive fitness and long-term environmental risks, competitive fitness has been rarely empirically determined in ecological risk assessment. In this study three transgenes, which increase salinity tolerance in Arabidopsis thaliana in growth chamber studies, were examined for impacts on plant fitness: (I) the abiotic stress response transcription factor C-repeat binding factor 3/drought responsive element binding factor 1a (CBF3/DREB1a), (II) the plasma membrane Na+/H+ antiporter Salt Overly-Sensitive 1 (SOS1), and (III) the mannitol biosynthetic enzyme mannose-6-phosphate reductase (M6PR). Transgene fitness impacts were examined across six field seasons and in the presence and absence of competition with the wild-type parental genotype at planting densities (2600/m2) chosen to replicate conditions observed in wild populations. Fourteen replicate competitive populations, initially 1:1 transgenic:wild-type mixes, of each transgenic line (2-3 lines/transgene) were maintained separately for six generations to allow transgene frequencies to fluctuate according to genetic drift and field selective pressures. Transgene frequencies were monitored each generation via phenotypic screening of progeny seed for presence of the co-integrated kanamycin resistance trait; low frequency populations were verified by qPCR analysis to rule out artifacts due to possible gene silencing. The fitness effects observed in competition with WT differed from relative fitness in pure populations. In pure populations, CBF3 lines showed moderately negative fitness relative to wild-type, but decreased to near extinction in direct competition. SOS1 lines performed equivalently to wild-type in pure populations but decreased in frequency by 50% in competition. The fitness of both M6PR lines was enhanced relative to wild-type in field pure populations, but in competition one line exhibited a competitive advantage while the other was selectively neutral and exhibited random drift. Selection and drift modeling, incorporating…

▼ Senescence is critical for plant survival and fitness as it ensures the most efficient use of nutrients for development and production of offspring. Senescence is a genetically controlled and hormone-mediated programme. Besides being induced in an age-dependent manner, senescence can also be initiated precociously from harvest-induced stress such as light- and sugar-deprivation. Understanding the biological mechanisms behind dark-mediated senescence is important as it helps to provide a new strategy for extending shelf life of crop plants. This project aims to understand the regulation of dark-induced inflorescence senescence in model plant Arabidopsis thaliana by using a forward genetic approach. Arabidopsis mutants showing accelerated and delayed inflorescence senescence (named ais and dis) were identified previously. Here, I rescreened 23 mutants and confirmed the altered time to senescence phenotype of nine mutants, including two ais and seven dis mutants. Of those, the dis2, dis9, dis15 and dis51 mutants were used for further analysis. The delayed degreening phenotype was also observed in detached dark-held leaves of dis2 and dis51 mutants, indicating that the causal mutations affected genes that regulate both leaf and inflorescence senescence. Segregation analysis was used to determine the genetic nature of dis traits in the dis2 and dis51 mutants. The dis2 trait was found to be monogenic recessive while the dis51 trait is dual-genic recessive. The dis2 mutant showed an extended “stay-green” phenotype and retained higher chlorophyll (Chl) b than Chl a. These findings were consistent with a lesion in the NON-YELLOW COLORING1 (NYC1) gene. Sequencing revealed a C/T transition in exon 8 of NYC1, which caused a highly conserved proline to be substituted by serine at amino acid position 360 of the NYC1 protein. By contrast, dis51 retained a similar amount of Chl a and Chl b. One of the genetic lesions in this mutant was mapped to a ~665 kb region at the top arm of chromosome 5 by using High Resolution Melt (HRM)-based mapping technology. The ETHYLENE INSENSITIVE2 (EIN2) gene was considered as a promising candidate because similar phenotypes were observed in ein2 mutants and dis51 seedlings did not show triple response when treated with the ethylene precursor ACC in the dark. PCR-based sequencing showed a G to A mutation in exon 6 of EIN2, resulting in a premature stop codon, which thereby resulted in a truncated EIN2 protein missing part of the C-terminal region that is required for ethylene signal transduction. In addition, the dis51 mutant emitted a pleasant aroma, which is abnormal in Arabidopsis. Four compounds (benzaldehyde, benzyl alcohol, phenylacetaldehyde and phenylethanol) were detected by using GC-MS analysis. However, it is not clear if the mutation causing the aroma phenotype also contributed to the dis51 phenotype. The mutations in the dis9 and dis15 mutants were previously mapped to chromosome 3 and chromosome 2, respectively. Here, further HRM and whole genome sequencing (WGS) data analyses were… Advisors/Committee Members: Dijkwel, Paul (advisor).

▼ To identify novel and essential components of the plant membrane trafficking mechanisms, Arabidopsis membrane trafficking mutants from fluorescent protein-based forward genetic screens were characterized. First, four novel glutathione synthase (GSH2) mutant alleles featured swollen endoplasmic reticulum (ER)-derived bodies that accumulated a soluble secretory marker. Consistent with the role of GSH2 in glutathione biosynthesis, the loss-of-function mutant alleles exhibited gamma-glutamylcysteine (γ-EC) hyperaccumulation and glutathione deficiency. The aberrant ER morphology was ascribed to the γ-EC accumulation. Redox-sensitive fluorescent protein revealed that gsh2 seedlings maintained a reduced cytoplasm at steady state but were more sensitive to oxidative challenge. Second, Mut 21 was a conditional mutant that accumulated a secretory marker in the alkalized apoplast at restrictive temperature (31˚C). The mutant was identified as carrying a mutant allele of tuftelin-interacting protein 11 (TFIP11), which has been implicated in regulating redifferentiation and cell proliferation through a cytokinin signalling pathway. Hence, it was postulated that the changes in response to cytokinin affect auxin-mediated acidification of the apoplast. Third, Mut 43 was a conditional mutant that accumulated a soluble secretory marker in the ER and unidentified punctate structures at restrictive temperature, and exhibited perturbations in ER export of a soluble protein marker. Moreover, the mutant showed severe growth defects and abnormal radial root swelling in the apical elongation zone. A mutation identification method through deep-sequencing of the wild-type siblings in outcrossed heterozygous mutant families was developed and tested in Mut 43. At the time when this thesis was prepared, bioinformatic analysis has assigned Mut 43 to the bottom arm of chromosome two and predicted a 300kb mapping interval based on the observed bias in single nucleotide polymorphism ratios. This work demonstrates the feasibility of using forward genetics to study plant-specific aspects of membrane trafficking mechanisms and incorporates new technology to streamline the process of gene identification.

▼ To identify genes involved in auxin conjugate hydrolysis, we selected Arabidopsis thaliana mutants resistant to growth inhibition by IAA-phenylalanine (IAA-phe). Two IAA conjugate resistant mutants were isolated: icr1 and icr2. Neither of these strains appears to be a conjugate uptake mutant. Dose-response experiments have shown that the mutants are approximately 2- to 3-fold more resistant to IAA-phe and 3-fold more resistant to IAA-alanine than wild-type plants. Although IAA-aspartate is not a strong growth inhibitor of Arabidopsis, the mutants are ∼2-fold more resistant than wild-type plants at 250-1000 mM of IAA-aspartate. Conjugate hydrolysis experiments indicate that icr1 and icr2 hydrolyte at least as well as wild-types. The icr1 mutation is a homozygous, incompletely dominant trait and maps to the top of Chromosome V. The Arabidopsis strain carrying icr1 demonstrates two additional mutations: delayed germination and early flowering. Analysis of a backcross of icr1 to Ws showed that additional traits are not caused by icr2. The late germination trait demonstrates some genetic linkage to the icr1 locus. We have also used a microbial selection scheme as a separate approach to isolating the genes for conjugate hydrolysis. From an Arabidopsis cDNA library we selected a transformed yeast strain able to utilize IAA-phe as a source of phenylalanine. The 1800 bp cDNA from this transformed strain was found to be an exact match to Arabidopsis actin2. Plasmid loss was shown to be accompanied by an inability of the yeast to utilize IAA-phe. Furthermore, down-regulation of the yeast promoter driving actin expression resulted in an inability of the transformed yeast to grow on IAA-phe, indicating expression of the actin is required for growth on this conjugate. IAA-aspartate and IAA-valine also supported growth of the appropriate yeast strains transformed with Arabidopsis actin. Overexpression of yeast actin also allowed auxotrophs to survive on conjugate, indicating that the hydrolysis phenomenon is not limited to Arabidopsis actin. Conjugate hydrolysis assays using actin-transformed and-untransformed yeast demonstrated that although the IAA-bound amino acid was freed by the endogenous hydrolytic enzyme, the IAA is not released intact but is degraded in the process Advisors/Committee Members: Town, Christopher (Advisor).

▼ Protein phosphorylation is a key cellular regulatory mechanism. Phosphorylation can either activate or inhibit the function of a particular protein. Activation of protein kinases has been implicated in response to light, pathogen attack, growth regulators, stress and nutrient deficiency in plants. Most of the intracellular signaling pathways use protein phosphorylation to create signals and conduct them further. Identification of the physiological substrates for the protein kinase enables the understanding of how the signaling networks function and how they are disturbed under adverse conditions. Identification of the physiological substrates for the kinase is limited by the low stoichiometry of protein phosphorylation inside the cell. Although, recent advances in mass spectrometric techniques have increased the identification of phosphorylated protein in the cell, the precise connection between the kinase and identified phosphorylated protein is not established. Dual-specificity kinases that phosphorylate on serine, threonine and tyrosine residues have been identified and characterized in plants. However, the in vivo substrates for most of these kinases have not been identified. Recently a manganese-dependent dual-specificity STY protein kinase (STYK) has been identified from Arabidopsis thaliana which has been suggested to play a role in plant growth, development and in systemic acquired resistance. The identification of the physiological substrate for AtSTYK may help in understanding the signal transduction pathway the kinase in involved and how it is perturbed in different physiological condition.

▼ Forward genetic screen was performed in Arabidopsis thaliana to isolate novel genes involved in leaf development. The tarani (tni) mutant was selected for further study based on its unique cup-shaped lamina with +ve Gaussian curvature. We show that the larger size of tni leaves is due to rapid growth rate due to excess and prolonged cell division. We monitored the front of the receding cell division zone as a function of time and showed that the shape of the front is more concave compared to wild type, leading to positive curvature. Application of gibberellic acids (GA) synthesis inhibitor rescued the positive curvature of tni suggesting a role for GA in maintaining leaf flatness. Overexpression of cell cycle inhibitor KRP2 also flattened the leaf, confirming a role of cell division. The floral organs and seed are also larger in the tni mutant. Besides growth, tni trichomes are hyper-branched which usually happens when there is more endoreduplication. We found that the nuclei of tni trichomes are larger than wild type nuclei, suggesting increased DNA content. Genetic interaction studies showed that TNI works independent of other trichome branching genes such as with TRYPTICHON and FURCA1. Map-based cloning showed that tni is positioned on left arm of the 3rd chromosome. Using molecular markers, we narrowed down to interval to a 65 kb region, which codes for 19 genes. Sequencing several of them revealed a G→A transition at the 3rd intron - 4th exon junction of At3g20630 gene. RT-PCR analysis showed the presence of an additional full-length transcript with extra un-spliced 3rd intron. Overexpression of this un-spliced variant in wild type plants produced phenotypes like hyperbranched trichomes and cup-shaped leaves; plus additional phenotypes like organ fusion and organ polarity defects. Complementation and allelic tests confirmed that TNI codes for AtUBP14, an ubiquitin protease. The tni plants have longer stem and roots which grow at faster rate compared to wild type. Confocal microscopic analysis of mature embryos showed that both shoot (SAM) and root apical meristems (RAM) of tni plants are larger in size. In RAM, the numbers of quiescent center (QC) cells and stem cells have increased in tni plants. The tni inflorescence and flowers are bigger than wild type in size. Also the degree of axillary shoots has increased in the tni plants. Overexpression of the splice variant of TNI produced undifferentiated callus-like structures in the shoot apex and in hypocotyl. All these phenotypes show that TNI is involved in meristem proliferation. The tni siliques produced many un-fertilized ovules and shrunken and malformed seeds suggesting gametic and/or embryo lethality. We observed that tni embryos were mis-patterned at various stages of development. Following the cell division pattern shows that cells arising from the ‘basal cell’ of the embryo take apical cell fate in tni embryos. The topmost cell of the suspensor, which is also the precursor cell of RAM, is not specified as hypophysial cell in several tni embryos. In… Advisors/Committee Members: Nath, Utpal (advisor).

Thesis Ph. D. Michigan State University. Cell and Molecular Biology 2018

The light reactions of photosynthesis convert harvested light into chemical energy that can be utilized by cells for metabolism. Through the translocation of protons across the thylakoid membrane coupled to electron transfer reactions, the photosynthetic proton motive force (pmf) is used to drive the production of ATP synthesis. Detailed studies have characterized the molecular processes of pmf–mediated feedback regulation of photosynthesis via changes in luminal pH from the light-induced proton gradient (ΔpH). While it is now well established that the photosynthetic pmf in higher plants consists of both a ΔpH and an electric potential (Δψ), the impact that Δψ exerts on photosynthesis in vivo is mostly unstudied. The Δψ component, however, influences the relative free-energy between redox mediators of electron transfer within membrane complexes. We found that in plants, a large in vivo Δψ increases photoinhibition through photosystem II (PSII) damage. High Δψ levels were observed in mutants with high steady-state pmf levels, as well as in wild type plants during light fluctuations. The increase in photoinhibition is primarily due to increased yields of electron recombination in PSII, which generate reactive oxygen species (ROS). The yield of PSII recombination when Δψ is large is mediated by ΔpH-dependent photosynthetic downregulation to decrease the concentration of reduced electron acceptors in PSII (QA-) capable of recombining and generating ROS. The ability to regulate photosynthetic light capture and electron transfer via pH–dependent processes as well as the need for photosynthetic organisms to mitigate a large Δψ leads me to propose that the photosynthetic organisms have evolved regulatory processes to mediate the bioenergetic limitations imposed by the Δψ effect on electron transfer. In a population of natural Arabidopsis thaliana accessions, variation in the kinetics of activating and deactivating pH-dependent downregulation of photosynthesis allowed the genetic loci responsible for the kinetics within this population to be mapped. These results suggest that photosynthetic organisms have evolved multiple mechanisms to regulate how rapidly photosynthesis is regulated by the pmf. The partitioning of pmf between Δψ and ΔpH allows a plant to balance the induction and relaxation of photoprotective mechanisms at the detriment of light utilization, while minimizing the impact of Δψ-mediated PSII recombination and ROS production. The processes work in concert to minimize potential photodamage and loss of productivity that occurs due to biophysical alterations in electron transfer processes mediated by Δψ.

▼ Throughout this dissertation I approach the long-term aim of improving photosynthesis through the lens of natural genetic variation for photosynthesis. To date few studies have directly asked how photosynthetic variation might inform or provide the genetic material required to enhance photosynthesis, despite the clear utility of this strategy for other types of agronomic improvement. Of the many traits underling variation in photosynthesis, mesophyll conductance – the diffusional flux of CO2 through the leaf interior – has potential to improve both photosynthesis and water use efficiency. I assess genetic variation for photosynthesis among ecotypes of the model plant Arabidopsis thaliana and cultivars of soybean (Glycine max). In both species, and across both controlled and field environments in soybean, I find heritable genetic variation for mesophyll conductance that is positively correlated to variation in photosynthetic rate, indicating that selection to enhance mesophyll conductance will increase photosynthesis. Genetic variation in mesophyll conductance though was largely unrelated to variance in water use efficiency as a result of phenotypic correlation between stomatal and mesophyll conductance. If trait variation is to prove useful for crop breeding, that trait must not have already been improved in the varieties currently used by farmers. In soybean, photosynthesis has improved slightly with breeding for yield across a historical set of cultivars. Mesophyll conductance is not responsible for this increase in photosynthesis; it remains unchanged after 75 years of selection for yield. Stomatal conductance is greater in modern varieties and I show that this increase scales from the leaf to the canopy. Greater canopy conductance in modern soybeans resulted in lower canopy temperatures and reduced leaf heat-stress. Few leaf-level photosynthetic traits were improved across this historical set of soybean cultivars. Given that I observed heritable genetic variation for mesophyll conductance among a small sampling of available soybean germplasm, there is substantial opportunity to harness this variation for the improvement of photosynthetic efficiency.

▼ The efficiency of photosynthesis results from the composition and organization of the plant’s internal structural components as well as the capability of response to environmental fluctuations. This thesis aims at identifying the genetic loci that are regulating the (sub-) processes in photosynthetic acclimation to increased irradiance levels, in order to obtain the genetic information useful to breed for photosynthetic performance. It uses genome wide association studies (GWAS) to reveal which genetic loci are being exploited in nature for keeping good photosynthetic performances in natural conditions. Phenotypic variation among natural accessions in photosynthetic light use efficiency response to increased growth irradiance is related to its variation in genetics in order to identify the associated genetic loci. In Chapter 2 is described which light environment reveals most natural variation in photosynthetic performance and for which photosynthetic parameter this is. It shows different Arabidopsis accessions display different photosynthetic responses to various light environments, well relatable to genetic differences. A candidate gene list for the direct response to increased growth irradiance was revealed after performing genome wide association analysis. Chapter 3 elaborates on the genome wide association results by visualizing the dynamics of the associated genetic loci over the time course of the photosynthetic response to increased irradiance. It shows it is possible to simplify the complexity of photosynthetic physiology as well as the genetic analysis in such way to confirm the causal genes underlying the associated loci, by confirming this for the YELLOW SEEDLING 1 (YS1) gene, a gene encoding a Pentatrico-Peptide-Repeat (PPR) protein involved in RNA editing of plastid-encoded genes essential for photosystems I and II. Genetic variation for any trait can be on the transcriptional level or on the functional level. In Chapter 4, the gene regulation in three Arabidopsis accessions with contrasting photosynthesis efficiency responses to increased irradiance is studied. These differences in photosynthesis efficiency are associated to differences in activation extents of heat responsive genes as well as to differences in the presence of a gene activation pathway acting on membrane lipid remodelling, suggested to maintain balanced cellular phosphate concentrations. Chapter 5 confirms the significance of maintaining balanced cellular phosphate concentrations for photosynthesis efficiency responses to increased irradiance. It describes how genome wide association mapping and linkage mapping combine to reveal genetic epistatic interactions between PHOSPHATIDIC ACID PHOPSPHOHYDROLASE 2 (PAH2, phosphate metabolism gene) and ASPARAGINE SYNTHETASE 2 (ASN2, nitrogen metabolism gene), both acting in the delivery of orthophosphate in the chloroplast. In conclusion this thesis contributes new insights into the physiological and molecular pathways underlying photosynthesis responses to increased growth irradiances.

▼ The plant hormone ethylene is an important regulator of plant growth and development, including senescence, abcission, fruit ripening, and responses to biotic and abiotic stresses. To find new members of the ethylene signaling pathway, a genetic screen for suppressors of the ethylene-insensitive mutant etr1-2 was performed. One mutant identified in this screen, etr1-11, is an intragenic mutation within ETR1. etr1-11 is a unique missense mutation that appears to eliminate ETR1-2 signaling. Mutant analysis further revealed that etr1-11 is a partial loss-of-function allele. The rte3 (reversion to ethylene sensitivity3) mutant was another mutant isolated in a genetic screen for suppressors of etr1-2. After testing other ethylene responses, such as leaf senescence, and performing epistasis analysis with other ethylene signaling mutants, it was determined that RTE3 is unlikely to play a direct role in the ethylene signaling pathway. Instead, RTE3 appears to be responsible for promoting hypocotyl elongation in etiolated seedlings in the ethylene triple response assay. The RTE3 gene was identified by positional cloning, and is predicted to encode a protein with an annotated SAC3/GANP domain. SAC3/GANP domains are present in proteins that participate in large multi-peptide complexes, such as the 26S proteasome regulatory subunit and the eIF3 translation initiation complex. Similarities in protein composition between these two complexes and the COP9 signalosome (CSN) suggest that a SAC3/GANP domain-containing protein may interact with members of the CSN. Interestingly, yeast two-hybrid analysis reveals that RTE3 interacts with EER5 and EIN2, proteins that have been shown to interact with members of the CSN. In addition, rte3-1 ein2-1 seedlings show a synthetic phenotype of delayed growth. Protein localization using a GFP tag reveals that RTE3 and EER5 both localize to the nucleus. These interactions suggest that RTE3, EER5, EIN2, and the CSN form a protein complex that regulates seedling growth. Advisors/Committee Members: Chang, Caren (advisor).

▼ One of the most important developmental processes in the life-cycle of higher plants is the transition from a seed to a plant and from a generative to a vegetative developmental program. The major hallmark or end-point of the transition from seed to plant is the onset of photosynthesis and the concomitant shift from a heterotrophic to an autotrophic organism. It is advantageous for a species to keep the period of seedling establishment as short as possible since young seedlings are highly sensitive to biotic and abiotic stresses. This implies that the extreme stress tolerance of seeds to i.e. desiccation is lost upon germination. If the regulatory principles of the seed-to-seedling transition are better understood it may become feasible to maintain the seed’s stress tolerance well into the seedling stage. Despite the profound impact of seedling performance on crop establishment and yield, the seed-to-seedling transition has hardly been studied at the molecular level. This thesis aims at deciphering and understanding the molecular processes that govern this transition in Arabidopsis thaliana. A high-resolution study of the molecular events that occur during these successive transitional stages may provide clues as to the regulatory principles that drive this transition. It may also yield information about the factors that determine the (in)ability to revert to a developmental mode and which features are critical for the maintenance and loss of desiccation tolerance and other stress responses. In Chapter 1 important processes such as abscisic acid and their regulation are described and it is discussed in what way the seed-to-seedling transition may have links to a trait such as desiccation tolerance. An overview is presented of the current knowledge of the seed-to-seedling phase transition and the existence of a temporal developmental block that can be manipulated by osmotic treatment, the carbon/nitrogen balance and by abscisic acid which results in the re-establishment of desiccation tolerance. Chapter 2 focuses on comprehensive gene regulation by a detailed transcriptional analysis across seven developmental stages of the seed-to-seedling transition. It describes the inference of a gene co-expression network and several transcriptional modules. I show that such an approach highlights important molecular processes during seedling development, which would not likely be derived from comparative transcript profiling. Moreover, I show that a putative key regulator in one of the transcriptional modules affects late seedling establishment. In Chapter 3 it is shown how this phase transition is expressed in the primary metabolite profiles in correlation with gene expression. A metabolite-metabolite correlation analysis suggested two profiles, which point at the metabolic preparation of seed germination and of vigorous seedling establishment. Furthermore, a linear correlation between metabolite contents and transcript abundance… Advisors/Committee Members: Wageningen University, Harro Bouwmeester, Henk Hilhorst, Wilco Ligterink.

▼ The life cycle of most plants starts, and ends, at the seed stage. In most species mature seeds are shed and dispersed on the ground. At this stage of its life cycle the seed may be dormant and will, by definition, not germinate under favourable conditions (Bewley, 1997). Seasonal dormancy cycling is a characteristic found in plant seeds. Being able to cycle in and out of dormancy allows the seed to survive decades or even centuries, allowing germination to be spread over time, but only when optimal conditions are available, not only for germination but especially for seedling establishment. In this thesis we have attempted to further elucidate the mechanisms behind dormancy, germination and dormancy cycling. Sisymbrium officinale seeds need nitrate and light to start germination (Chapter 2, 3, 4, 6). Nitrate acts in part by reducing the abscisic acid (ABA) levels (a plant hormone that elevates dormancy levels). The action of light and nitrate can also be reached by applying gibberellins (GAs) to the seeds (Chapter 2, 3, 4, 6). GAs are capable of inducing enzymes that hydrolyze the ensdosperm walls (Debeaujon and Koornneef, 2000; Chen and Bradford, 2000; Nonogaki et al., 2000; Manz et al., 2005) In this way GAs could be involved in lowering the physical restrictions imposed by the resistance of the seed coat and the endosperm. On the other hand, GAs may also increase the embryo growth potential. For successful survival of the dormant seed, metabolic activity is reduced to avoid rapid depletion of reserves. The metabolic activity of the seed was measured using electron paramagnetic resonance (EPR), with TEMPONE as a spin probe, and the respiratory activity was measured with the Q2-test (Chapter 2).We showed that primary dormancy was accompanied by hardly any metabolic or respiratory activity, and this increased considerably when dormancy was broken by nitrate. However, when the light pulse was not given and the seeds had become secondary dormant the metabolic activity slowed down. Regulation of dormancy is tightly linked with abiotic stress factors from the environment. The regulation and survival of the seed under stress conditions is largely dependent on the composition of the cytoplasm. We tested this by EPR, using carboxyl-proxyl (CP) spin probe (Chapter 4). The primary dormant and sub-dormant seeds possessed a higher viscosity than the germinating seeds. The viscosity of secondary dormant seeds appeared intermediate; however, the ease at which the vitrified water melted was similar to that of primary dormant seeds. As a result of the differences in viscosity, the temperature of vitrified water melting differed between the different dormancy states. The changes in cytoplasmic viscosity and vitrified water melting may be linked to changes in metabolism and the content of high molecular weight compounds. As membranes are the primary target for temperature perception, they are often implicated in regulating dormancy. Therefore, Hilhorst (1998) put forward a… Advisors/Committee Members: Wageningen University, Linus van der Plas, Henk Hilhorst, P.E. Toorop.

However, in long-term responses to low VPD, adaptation processes occur which make stomata less sensitive to stimuli which usually induce stomatal closure (stomatal malfunctioning). Cellular mechanism(s) leading to occurrence of stomatal malfunctioning is (are) still unknown. The aim of this project was to elucidate the processes that are involved in the malfunctioning of stomata after long-term exposure to low VPD. To elucidate whether the problem of stomatal malfunctioning is due to alterations in stomatal morphology and leaf anatomy or in the ABA signalling pathway, fava bean plants were grown at low or moderate VPDs and some plants that developed their leaves at moderate VPD were then transferred for four days to low VPD. Leaf anatomical and stomatal morphological alterations due to low VPD were not the main reason of stomatal malfunctioning in response to ABA and desiccation. Within one day exposure to low VPD, the level of foliar ABA decreased to the same level as in low VPD-grown plants, while the level of ABA-glucose ester was not affected. Spraying ABA during a 4-day exposure to low VPD maintained closing ability of the stomata after 4-day low VPD-exposure. Therefore, alteration in the signalling pathways due to low foliar ABA level was recognized as the main reason for stomatal malfunctioning after long-term low VPD-exposure. Coincidence in changes of Ca2+, ABA receptors, and positive and negative regulators of ABA signalling are proposed as early steps for stomatal malfunctioning induced by low VPD-exposure. Transcriptional activators, transcriptional repressors as well as E3 ligases are proposed for long-term adaptation of cellular processes which consequently cause decreased stomatal response to closing stimuli afterwards. In order to find the molecular mechanism(s) of stomatal malfunctioning, possible variation in stomatal response to closing stimuli was studied among Arabidopsis thaliana accessions after a 4-day low VPD-exposure. Accessions could be grouped to very sensitive, moderately sensitive and less sensitive to closing stimuli using principle component analysis. A positive correlation was found between foliar ABA level (before desiccation) and stomatal closure response to ABA (but not to desiccation) after exposure to different VPDs. Stomatal response to desiccation was positively correlated with the foliar ABA level after desiccation. In order to elucidate the molecular network underlying stomatal malfunctioning in response to ABA due to long-term low VPD-exposure, two groups of Arabidopsis accessions were used… Advisors/Committee Members: Wageningen University, Ernst Woltering, Uulke van Meeteren.

▼ English summary Zinc is an important structural component and co-factor of proteins in all living organisms. The model plant species for genetic and molecular studies, Arabidopsis thaliana, expresses more than 2,000 proteins with one or more Zn binding domains. Low Zn availability in arable soils is a widespread problem around the world which results in agricultural losses and the production of grains with low Zn content. The long-term consumption of low-Zn-content food items leads to severe health problems in humans as a result of severe or mild dietary Zn deficiency. Hence the importance of studying Zn homeostasis in plants and mechanisms involved in Zn deficiency tolerance aiming to enhance Zn concentration in plants edible parts and to develop varieties with a higher tolerance to Zn deficiency. Plants are sessile organisms which trough evolution have developed specific traits in order to adapt to certain environmental conditions in their surroundings. As a result some plant genotypes are more tolerant to Zn deficiency and when exposed to low Zn conditions are able to perform better than others. To investigate the physiological mechanisms involved in Zn deficiency tolerance I examined natural variation present in a set of twenty diverse Arabidopsis thaliana accessions. In chapter 2, differences in shoot biomass production, Zn usage index (ZnUI), ionome (concentration of elements) and expression level of six key Zn deficiency responsive genes were studied. Accessions did not show large natural variation for shoot Zn concentration under Zn deficiency, while the decreases in shoot biomass and ZnUI were more variable. The conclusion from this is that accessions differ for the minimum Zn concentration required for growth which is associated with differences in Zn deficiency tolerance. We also found that the gene expression levels of three Zn transmembrane transporters (IRT3, ZIP3 and 4) in shoot were positively correlated with ZnUI and shoot biomass, but negatively correlated with shoot Zn concentration. This implies that a higher tolerance to Zn deficiency in A. thaliana is associated with an increased Zn translocation from root to shoot under low Zn. Furthermore, I used a logistic regression model to demonstrate that differences in the shoot ionome can be used as a biomarker to identify the plant Zn physiological state. Based on the changes in the concentrations of some elements in each of the Zn deficiency treatments it was possible to predict the Zn physiological state of the plants similarly to when Zn concentration is used alone. The adaptive response to Zn deficiency involves physiological changes in shoots, but also in roots which play a key role in the acquisition of nutrients. In chapter 3 I used the same twenty A. thaliana accessions as described in chapter 2 to identify root system architecture traits and changes in the root ionome involved in a higher tolerance to Zn deficiency in plants. Similar to shoots, all accessions showed a… Advisors/Committee Members: Wageningen University, Maarten Koornneef, Mark Aarts.

▼ Plant performance implies complex traits, controlled by a large set of genes and affected by the environment. In this thesis we have tried to take the first steps in unravelling the genes controlling plant performance using naturally occurring accessions (ecotypes) of the model plant Arabidopsis thaliana and QTL (quantitative trait locus) analysis.Traits associated with plant performance (mainly the gain, the allocation, and the storage of carbon) have been studied to investigate if there is a relationship between various growth parameters, and between growth and flowering-related traits. We found limited variation for photosynthetic performance (measured as chlorophyll fluorescence) with the exception of the Ely accession. The difference in the growth parameters and the photosynthetic traits observed between Ely and the standard accession Landsberg erecta was probably due to the fact that the D1 protein of Ely encoded by the psbA gene, was mutated, leading to atrazine-resistance.Based on the natural variation that we found within Arabidopsis accessions for different traits that relate to plant growth, carbohydrate content and flowering time,four new recombinant inbred line (RIL) populations(L er x An-1, L er x Kas-2, L er x Kond and L er x Sha)of Arabidopsiswere developed and genotyped.QTL analysis for flowering time revealed12 to 16 different QTLs segregating for flowering time in these four populations.QTL analysis, using the RILs derived from the cross between L er and Sha, revealedfive genomic regionswhere QTLs for growth traits (plant areas, dry weight and RGR) are located.QTL analysis, using the RILs derived from the cross between L er and Kond that were grown on hydroponics, also revealed QTLs for the different aspects of plant growth-related traits, sugars and starch contents and flowering-related traits. From the significant correlations and the co-locations of the QTLs for these aspects, we conclude that there is a complex relationship between plant growth-related traits, carbohydrate content and flowering-related traits.This study shows that Arabidopsis natural variation can successfully be used to study the genetic basis of these complex traits.

▼ Synthetic dyes are capable of producing the whole color spectrum on account of their structural diversity but this diversity poses challenges in the degradation of dyeing wastes. Laccases and peroxidases from bacterial or fungal sources and parts of plants in the presence of hydrogen peroxide (H₂O₂) plus a mediator have been exploited in the bioremediation of synthetic dyes. However, intact plants have not found much favor despite their phytoremediation potential. The goal of this research was to further clarify ways by which whole plants bring about decolorization of different types of synthetic dyes. Hydroponically cultivated plants from two dicot families namely Arabidopsis thaliana and sunflowers (Helianthus annuus) were exposed to representative dyes from several classes: monoazo (Methyl Red and Methyl Orange), disazo (Trypan Blue, Evans Blue and Chicago Blue 6B), and arylmethane (Brilliant Blue G, Bromocresol Green, Malachite Green and Phenol Red). Tests were done in presence or absence of externally added H₂O₂, with or without a free radical mediator, 1-hydroxybenzotriazole, using UV-Visible spectrophotometry. The initial rate of decolorization and the overall percentage decolorization was calculated for each dye in the different treatments. Decolorization of the dyes from different classes varied between plant species and depending on the treatment. Except for Methyl Red, all dyes required added H₂O₂ as well as mediator to achieve rapid decolorization. Added H₂O₂ was found to be the limiting factor since it was degraded by plants within a few hours. Both species were able to slowly decolorize dyes upon daily addition of fresh dye even in the absence of added H₂O₂ and mediator, provided that nutrients were supplied to the plants with the dye. A. thaliana was found to be more effective in dye decolorization per gram tissue than sunflower when treated under similar conditions. Analysis of the residual dye solution by ESI/MS did not reveal any potential by-products following the decolorization treatment with plants, suggesting that the plant roots might be trapping the by-products of dye decolorization and preventing their release into the solution. All these findings support the potential application of whole plants for larger scale remediation. Advisors/Committee Members: Lawrence C. Davis.
