▼ Information on genetic variability and stability of yield and yield components of sunflower in Zambia is lacking. The study was undertaken to determine the magnitude of yield; determine the relationships between yield and it's components; and estimate the heritability and stability of important traits in sunflower. Twenty five genotypes representing a random sample of the breeding populations in an on going sunflower improvement programme were grown in a 5 X 5 triple lattice design in 5 locations in the 1993/94 growing season. Data on kernel yield, kernel yield/head, oil content, oil yield, head diameter, stem diameter, plant population, plant height, average number of leaves/plant, number of days to 50% flowering, 1000 kernel weight and kernel % were collected and/or derived. The magnitude of yield was determined at harvesting. The relationship between yield and it's components was determined by path coefficient analysis. Presence of genetic variability was indicated by significant genetic variance. Heritability was estimated from variance components. Stability analysis was also done. The magnitude of kernel yield was found to be comparable with world averages though the average kernel yield of 1163 Kg/ha was below the country range of 1500 to 2000 Kg/ha) due to poor rains. High correlations between kernel yield and plant height (r = 0.420**), stem diameter (r = 0.589**) and kernel yield/head (r = 0.658**) were observed but their direct effects on kernel yield were very small (-0.216, -0.154 and -0.189 respectively). However, their indirect effects were more positive mostly through head diameter (0.127, 0.174 and 0.141 respectively). Head diameter showed large direct effects on both kernel yield (0.311) and oil content (0.581). The direct effect of 1000 kernel weight on oil yield (0.173) was large relative to overall correlation (r = 0.195**). The genetic variances for kernel yield, oil content, oil yield, head diameter, plant height, kernel yield/head and 1000 kernel weight were significant (P < 0.05). The broad sense heritability estimates for kernel yield ranged from 5.42% in Golden Valley to 33.01% in Monze; overall the estimate was 7.12%. For oil content the estimates ranged from 14.95%) in Mt Makulu to 52.35% in Monze with an overall estimate of 11.43%i. Similarly those of oil yield, plant height, stem diameter and 1000 kernel weight ranged from 8.36% in Golden Valley, 9.36% in Monze, 5.77% in Mt Makulu and 5.54% in Mt Makulu respectively to 26.78%) in Monze, 61.96%) in MRS, 27.27%o in Mt Makulu and 37.66%) in Monze respectively with the overall estimate being 20.37%, 10.20%), 0.23%), and 2.51% respectively. For head diameter the estimate was 17.33%) in Mt Makulu and 2.97% overall. Genotype X location interaction effects were significant for kernel yield, oil yield, 1000 kernel weight, stem diameter and plant height. Sunflower with respect to kernel and oil yield showed average ability to be consistent across locations. Overall the magnitude of yield was found to fall within an acceptable range with genetic…

▼ In the present study, a total of twenty (20) tomato genotypes were evaluated simultaneously under greenhouse and field conditions in order to determine genetic variability present in the agronomic and fruit quality traits. The experiments were laid out in a Randomized Complete Block Design (RCBD) with three (3) replications. Both individual and combined analyses of variance were employed. The individual analysis of variance showed a significant (P < 0.01) variability among the genotypes for almost all characters studied. The components of variance estimated on individual location basis indicated a moderate to high GCV, high broad sense heritability as well as high genetic gain for almost all traits. However, stem diameter, pH and gallic acid recorded low estimated GCV under greenhouse conditions while plant height, stem diameter, chlorophyll content, number of days to 50 % flowering, fruit set percentage, number of days to fruit maturity and pH recorded lower estimates for GCV under field conditions. The combined analysis of variance (ANOVA) showed significant (P < 0.01) difference among the genotypes, locations and their interactions. The component of variance based on a two-factor analysis of variance revealed considerable effect of location and Genotype x Location interaction on the expression of traits especially, fruit phytochemical composition traits. Relative performance of the genotypes differed with location. Among the genotypes evaluated, MONGAL F1, PLATINUM F1, NKANSAH HT, WOSOWOSO, ROMA and SUMO F1 displayed superior performance for fruit yield across all locations. Large variation was observed among the genotypes for all fruit quality traits studied. Genotypes produced under greenhouse conditions recorded higher amounts of flavonoid composition while phenolic acids content were higher among field-produced tomato genotypes. Number of trusses per plant, number of fruits per plant as well as total fruit weight per plant showed a positive significant association with fruit yield under both greenhouse and field conditions. Consistency of correlation across the two locations was observed. However the correlation coefficients differed due to the effects of G x L interaction. Advisors/Committee Members: Blay, E.

▼ An understanding of the genomic diversity of plant pathogenic viruses is essential for devising control strategies. Over the last two decades, improved sequencing technologies and the discovery of RNA silencing have profoundly impacted our ability to understand the diversity of virus populations and develop resistant plants. In Chapter 1 of this dissertation, I critically evaluate the literature regarding materials providing resistance against viruses and vectors in Vitis species and discuss their availability for disease management. This review indicates little or no useful resistance toward most virus diseases, and the critical need to develop resistant materials. In Chapter 2, in order to gain insights into the evolutionary mechanisms of Grapevine fanleaf virus (GFLV), sequence information was obtained from fourteen isolates collected in naturally infected vineyards in California. My results indicated that some isolates result from interspecies recombination between GFLV and Arabis mosaic virus, and suggest that recombination and purifying selection are important evolutionary mechanisms in the genetic diversification of GFLV. In Chapter 3, I designed various resistance constructs derived from GFLV based upon an analysis of sequence variability. These constructs were tested for resistance to GFLV using a transient expression system. Results indicated that some of these constructs are capable of reducing virus titers in GFLV-infected plants. In Chapter 4, I reviewed the literature regarding environmental and human safety issues related to virus-resistant transgenic horticultural crops. My analysis suggests that the use of virus-resistant transgenic plants is a safe and effective way to control viral diseases. In Chapter 5, I present the results of a survey for Prunus necrotic ringspot virus in an orchard of sour and sweet cherry trees. Sequence analysis of the viral coat protein gene from various isolates indicated one predominant and several minor molecular variants. Results revealed a higher rate of infection among sour cherry vs. sweet cherry trees, and also suggested that this virus may have been transferred from a single infected sour cherry tree into the orchard by pollen transfer. In Chapter 6, I present conclusions regarding the implications of my research and suggest future directions of the work presented in the preceding five chapters.

▼ Bacterial brown spot (BBS) disease is a major disease in dry beans in South Africa causing yield losses of up to 55%. The overall goal of the research was to improve dry bean production through identifying high yielding and stable cultivars, with resistance to the BBS disease, classifying or detecting mega environments for dry bean production and to conduct prebreeding trials that will provide information that will contribute to BBS disease breeding in South Africa. Four hundred and twenty three Andean Diversity Panel (ADP) dry bean genotypes were screened for grain yield and BBS disease resistance in three regions. The plants were inoculated with three isolates of BBS strains or inoculum at 21, 28 and 36 days after planting. Disease severity was rated at 7, 14 and 21 days after the first infection and the relative area under disease progress curve (RAUDPC) was calculated. The analysis of variance revealed significant differences (P<0.001) in grain yield and BBS severity for genotype, environment and genotype by environment interaction (GEI). Genotypes were classified as resistant, moderate resistant and susceptible based on BBS severity and RAUPDC. The study identified 21.0% of the genotypes as resistant and 41.6% as moderately resistant to BBS disease. The RAUDPC was significantly (P<0.001) negatively associated with grain yield (r= -0.55). The small seeded genotypes showed lower RAUDPC than the medium and the large seeded, and genotypes with an indeterminate growth habit showed lower RAUDPC than those with a determinate growth habit. Genotypes ADP-0592, ADP-0790, ADP-0120 and ADP-0008 were selected for both resistance to BBS disease resistance and high seed yield across three environments. The best genotypes had grain yield above 1.45 t ha-1 across sites, and above1.85 t ha-1 at individual sites, and had grain yield above the grand mean (0.87 t ha-1) and the best performing cultivar (1.13 t ha-1), and mean BBS severity below the grand mean (39.85) and the best performing cultivar (31.67). These genotypes can be useful sources of genetic resistance for future dry bean improvement. Advisors/Committee Members: Melis, Robertus Johannes Maria. (advisor).

▼ The success of any breeding programme depends to a large extent on the amount of genetic variability present in the working population at the disposal of the breeder(s). An experiment was set out to assess the genetic variability among 79 accessions of natural dura oil palm collected in Ghana and conserved at OPRI by evaluating 18 agro-morphological traits, 11 years after field planting. The 79 dura oil palms accessions were laid out in an augmented design with two checks on each block. Data were collected on vegetative, yield and yield related characters (bunch and fruit characters). Collected data were analysed using R-statistical software. Results revealed significant variation among the 79 dura oil palm accessions for all traits except total fronds, average bunch weight, percent fruit to bunch and percent kernel to fruit. Heritability (h2), ranged from 0 to 85.27 %, genetic coefficient of variation (GCV) from 0 to 68.74%, phenotypic coefficient of variation (PCV), from 7.74 to 95.76% and genetic advance (GA), from 0 to 12.72 %. Fresh fruit bunch and bunch weight exhibited high values for h2, GCV and moderate GA suggesting a high potential for improvement through selection and better response to selection. Five axes were identified using the principal components (PCs) with Eigen values greater than one explaining 74.82% of the total variance. The first to fifth components accounted for 34.25%, 15.10%, 11.86%, 7.47% and 6.13% of the variation respectively. Accessions GHA 217/02, GHA 221/02, GHA 225/03, GHA 212/02, GHA 203/02, GHA 201/01, GHA 202/01, GHA 221/04, GHA 209/02, GHA 202/02 and GHA 211/02 were phenotypically distant (more diverse) and could be selected for the improvement of the oil palm. Cluster analysis also resolved the accessions into two main clusters based on the 18 agro-morphological traits at 98 % dissimilarity index. Six pairs of accessions were identified as potential duplicates. There was no correlation between clustering and location of collection. Generally, significant positive correlations were found among the vegetative and yield characters while negative correlations were found between vegetative and yield traits on one hand and bunch and fruit characters on the other hand. There was a perfect association between the fresh fruit bunch and bunch weight. Potential accessions were identified and have been recommended for utilization in future improvement of the crop. The results suggests potential for effective utilisation of the dura collections in the OPRI’s oil palm breeding programmes and the possibility of establishing a core collections of dura oil palm from the germplasm collection evaluated in this work.

▼ Bones have a large intrinsic capacity for repair and regeneration following an injury, however, an estimated 5-10% of nearly 8 million fractures that occur every year in the United States lead to nonunions. The process of bone regeneration is a complex trait that brings together different complements of molecular and cellular interactions to carry out its necessary mechanical functions. These interactions may be attributable to the effects of genetic variations that contribute to differences in bone morphology and fracture healing. This study was undertaken to determine how genetic variability that controls phenotypic qualities of bone affect rates and patterns of fracture healing. Three inbred strains of mice (A/J (AJ), C57BL/6J (B6), and C3H/HeJ (C3)) with known structural and biomechanical differences resulting from fetal bone development were examined. Transverse fractures were generated in the femur and healing traits were evaluated using quantitative real-time polymerase chain reaction (qRT-PCR), micro-computed tomography (μCT), biomechanical torsional testing, and cartilage contrast-enhanced micro-computed tomography (CECT). The temporal analysis of gene expression revealed that B6 had the longest duration of chondrocyte maturation and the greatest relative expression of osteogenic genes relative to either C3 or AJ. While AJ and C3 exhibited similar patterns of chondrogenesis, AJ initiated osteogenesis earlier than C3. These results suggest that compared to either AJ or B6, the C3 strain exhibited the least temporal coordination between the chondrogenic and osteogenic stages. Consistent with the relative patterns of RNA expression, μCT evaluations at day 21 post fracture showed that B6 had higher callus mineralization than AJ and C3. μCT, cartilage CECT, and biomechanical testing revealed less tissue mineralization and more cartilage near the fracture gap, which indicated a less developed bony bridge in C3 calluses at day 21 post fracture. The lack of large amounts of cartilage in calluses of all strains by day 21 indicated that all strains had initiated osteogenesis by this time. Taken together, these results showed that mice with different genetic backgrounds express different patterns of mobilization and renewal of skeletal stem cells with differing temporal progressions of chondrogenic and osteogenic differentiation. These data further show that these variations affect the phenotypic properties of fracture calluses during the process of fracture healing.

Dobijeni rezultati su dali potpuniju sliku o nivou i tipu genetičke varijabilnosti selekcionisanih populacija livadskog vijuka, što omogućava izbor najpogodnijeg metoda oplemenjivanja ove travne vrste u narednom periodu. Početni materijal u ovim istraživanjima predstavljale su dve selekcionisane populacije livadskog vijuka, poreklom od prve domaće selekcionisane sorte livadskog vijuka Kruševački 21 (K-21) i švajcarske sorte Pradel. Potomstvo za ispitivanje genetičke varijabilnosti dobijeno je tokom 2008. godine kontrolisanim oprašivanjem slučajno odabranih biljaka iz obe populacije, po proceduri koju su za stranooplodne biljke predložili Comstok i Robinson (1948). U cilju ispitivanja dobijenog potomstva ogled je postavljen po NC I modelu ukrštanja sa setovima u okviru ponavljanja. Kod populacije K-21 je proučavano 20 half-sib potomstava, odnosno 60 full-sib potomstava. Kod populacije Pradel proučavano je 13 half-sib potomstava, odnosno 39 full-sib potomstava. U okviru svakog full-sib potomstva proučavano je po 30 biljaka. Tokom izvođenja ogleda praćene su sledeće osobine: vreme metličenja, odnosno stasavanja, visina biljaka, dužina, širina i broj listova, dužina metlice, broj vegetativnih i generativnih izdanaka, prinos zelene mase i suve materije po biljci u prvom otkosu i ukupan prinos zelene mase i suve materije po biljci. Od osobina hemijskog sastava suve materije proučavana je varijabilnost sadržaja sirovih proteina (gkg-1), ADF-a (gkg-1) i NDF-a (gkg-1). Za sve proučavane osobine kod obe proučavane populacije tokom obe godine istraživanja utvrđene su srednje vrednosti kao i vrednosti odgovarajućih standardnih grešaka. Takođe je kod obe populacije u obe godine zabeležen širok interval variranja, odnosno razlika između minimalnih i maksimalnih vrednosti, za sve proučavane osobine. Sve ovo govori o prisutnoj visokoj unutarpopulacijskoj varijabilnosti pručavanih selekcionisanih populacija livadskog vijuka...

Ekologija - Ekologija, biogeografija i zaštita životne sredine / Ecology - Ecology, biogeography and enviromental protection

Kompleks Campanula pyramidalis čine blisko srodni i morfološki slični taksoni široko rasprostranjeni na Balkanskom polustrvu, sa malim delom areala na jugu Apenina. Pored tipične vrste C. pyramidalis, koja je morfološki i molekularno jasno izdiferencirana i izdvojena u grupu "Pyramidalis", prema rezultatima najnovije filogenetske studije u ovaj kompleks spadaju i vrste C. austroadriatica, C. secundiflora i C. versicolor, koje su objedinjene u grupu "Versicolor". Kako odnos populacija iz kontinentalnog dela Crne Gore sa populacijama vrsta C. austroadriatica i C. secundiflora nije prethodnim studijama razrešen, kao i činjenica da se u vezu sa C. versicolor dovodi 19 taksona, ukazaje na potrebu detaljnijeg istraživanja grupe "Versicolor". Genetička i morfološka varijabilnost je analizirana na osnovu velikog broja sakupljenih populacija sa čitavog areala grupe "Versicolor". Horološki i ekološki podaci su prikupljeni obradom literaturnih podataka, revizijom herbarskog materijala i terenskim istraživanjima. Rezultati ove sveobuhvatne studije su pokazali jasnu morfološku, genetičku i fitogeografsku diferencijaciju unutar grupe "Versicolor". Molekularne analize (SSR) su pokazale visok stepen izdiferenciranosti analiziranih vrsta C. austroadriatica, C. secundiflora i C. versicolor unutar koje su izdvojene dve podvrste C. versicolor subsp. plasonii i C. versicolor subsp. tenorei, dok su populacije iz kontinentalnog dela Crne Gore izdvojene u novu vrstu C. montenegrina. Ovo je podržano morfometrijskim i fitogeografskim analizama. Na osnovu dobijenih rezultata predložen je novi preliminarni taksonomski koncept čitavog kompleksa C. pyramidalis, sa ključem za identifikaciju i opisima taksona, podacima o tipskim primercima, rasprostranjenju i staništima svih analiziranih taksona.

Existem poucas informações relacionadas com a comparação de populações de soja derivadas de cruzamentos com diferentes níveis de divergência genética (DG). Os objetivos deste trabalho foram comparar o desempenho de duas populações de soja derivadas de genitores com baixa e alta DG. Foram realizados dois cruzamentos com genitores diferindo quanto à divergência genética baseada em marcadores moleculares AFLP: baixa DG (IAC-12 x IAC-100) e alta DG (EMBRAPA-60 x EMGOPA-315). Para cada cruzamento foram obtidas 100 progênies F2:3, que foram avaliadas experimentalmente em três ambientes e, posteriormente, selecionadas as 25 progênies mais produtivas. Em seguida foram obtidas 10 linhas puras F5:7 de cada uma das 25 progênies, originando aproximadamente 250 linha puras de cada cruzamento. No ano agrícola 2012/13 foram conduzidos os experimentos de avaliação, utilizando um delineamento em parcelas subdivididas, onde as progênies foram alocadas nas parcelas e as linhas puras dentro de progênies nas subparcelas, e as parcelas arranjadas em um látice balanceado 5x5 (seis repetições). As subparcelas foram constituídas de linhas de 2 m, espaçadas de 0,5 m, contendo 30 plantas após o desbaste. Os caracteres avaliados foram: número de dias para a maturação (DM), altura das plantas na maturação (AM), acamamento (AC) e produção de grãos (PG). A partir da análise de variância foram estimados os seguintes parâmetros para cada cruzamento: média geral, amplitude de variação das médias das linhas puras dentro de progênies, variância genética entre linhas puras dentro de progênies (?^2l/p ), variância fenotípica entre médias de linhas puras dentro de progênies (?²/ F (l/p) ), coeficiente de herdabilidade entre médias de linhas puras (h ²/X(l/p) ) e resposta esperada com seleção (Rs). Para todos os caracteres, as médias gerais foram maiores para o cruzamento de maior DG. Para PG, AM e DM as estimativas das variâncias genéticas entre linhas puras dentro de progênies F5:7 foram maiores no cruzamento de maior DG, bem como as amplitudes de variação das médias das linhas puras. Consequentemente, a resposta esperada com seleção entre médias de linhas puras dentro de progênies para PG foi 47,6% maior, em média, bem como a proporção de linhas puras de alta produção, para o cruzamento de maior DG. Os resultados deste trabalho indicam que o uso das medidas de divergência baseada em marcadores moleculares AFLP na escolha de genitores para cruzamentos pode ser uma ferramenta útil para reduzir o número de cruzamentos e, consequentemente, aumentar a eficiência da seleção para produção de grãos em soja.

There is limited information in relation to comparison of populations derived from crosses with different levels of genetic divergence (DG) in soybeans. This work was carried out to compare the performance of two soybean populations derived from parents with low and high DG. From two two-way crosses of soybeans with different levels of AFLP molecular marker genetic divergence (DG): low DG (IAC-12 x IAC-100) and high DG (EMBRAPA-60 x EMGOPA-315), one…

A ampla variabilidade existente em milho deve-se às inúmeras variedades crioulas, genótipos importantes para o melhoramento, pois constituem fonte de variabilidade genética na prospecção de novos genes de interesse econômico. Os objetivos deste trabalho foram analisar a diversidade genética existente entre acessos de milho crioulo oriundos do Rio Grande do Sul e do Paraná a partir da análise do polimorfismo gerado pelos marcadores RAPD, microssatélite (SSR) e AFLP; realizar o agrupamento destes genótipos através das estimativas da similaridade genética e estabelecer possíveis relações entre a similaridade genética e os locais de coleta das variedades crioulas. As reações de PCR para cada marcador foram otimizadas através de protocolos específicos, sendo utilizados: 30 primers RAPD, 47 pares de primers SSR e 25 combinações de primers EcoRI + MseI para o marcador AFLP. Os fragmentos amplificados (RAPD e SSR) foram visualizados em gel de agarose a 2 e 3 %, respectivamente, através de corrida eletroforética horizontal por aproximadamente 4 h a 80 V. Os produtos da amplificação do AFLP foram resolvidos em gel de poliacrilamida (6 %) submetidos à corrida eletroforética vertical por 3 h e 30 minutos a 80 W (1500 V). A genotipagem das variedades de milho com o marcador RAPD amplificou 409 fragmentos com índice médio de polimorfismo de 81,9 %. O SSR gerou 134 fragmentos com 78,3 % de polimorfismo. Por outro lado, o AFLP amplificou 1889 fragmentos com índice médio de polimorfismo de apenas 40,3 %. Os fragmentos polimórficos foram submetidos às análises de similaridade genética através do coeficiente de Jaccard e de agrupamento pelo método UPGMA individualmente e conjuntamente para os marcadores. O coeficiente médio de similaridade foi de 57 % para o RAPD; 56 % para o SSR; 74 % para o AFLP e 69 % para a análise conjunta. Os dendogramas obtidos a partir do RAPD e SSR mostraram 8 grupos distintos, enquanto que o dendograma obtido a partir do AFLP e da análise conjunta formaram 6 e 7 grupos, respectivamente. De maneira geral, as correlações entre as matrizes de similaridade foram baixas, porém entre o AFLP e a análise conjunta foi de 96 %. Os resultados revelaram ampla variabilidade genética entre os acessos de milho crioulo. Os marcadores RAPD e SSR apresentaram os maiores índices médios de polimorfismo e o AFLP demonstrou maiores índices de similaridade genética entre os acessos crioulos. De maneira geral, os marcadores utilizados foram ferramentas eficientes para amostrar a diversidade genética e agrupar as variedades de acordo com os locais de coleta, embora possuam capacidade diferencial de revelar polimorfismo bem como para agrupar os acessos crioulos de milho.

The wide variability in corn is due to the numerous landraces, important genotypes for breeding programs, because they constitute a source of genetic variability in the exploration of new genes of economic interest. The objectives were to analyze the genetic diversity between landraces from Rio Grande do Sul and Paraná through the analysis of polymorphism generated…

▼ In this study, hypervariable region I (HVRI) of the mitochondrial DNA (mtDNA) control region, and five microsatellite loci were used to assess genetic variability and the extent of hybridization between the two fur seals (Arctocephalus tropicalis and A. gazella), that occur on Sub-Antarctic Marion Island. Both species were harvested during the 18th and 19th centuries, leading to a reduction in population size and the extinction of A. gazella at some localities. Whilst both species have recovered and are increasing in size, it is not clear to what extent sealing has affected genetic variation, although a more pronounced effect would be expected for A. gazella, given the more intensive harvesting of this species. The current study confirmed this hypothesis and revealed that A. gazella had a nucleotide diversity of 2.9 % whilst for A. tropicalis it was 4.2 %, across the HRVI mtDNA region sequenced. For microsatellite DNA, genetic variation in A. tropicalis was higher than in A. gazella in terms of the total number of alleles detected and the level of heterozygosity (HE=0.875, HO=0.845, mean number of alleles=13.6 and HE=0.799, HO=0.781, mean number of alleles=13, respectively). Diversity in both species is among the highest recorded in pinnipeds to date, and suggests that sealing did not overly affect the levels of genetic variation in these species. In terms of population structure, A. tropicalis show a high level of population structure, as indicated by the ΦST of 0.32 between Marion and Gough Island. Furthermore, the A. tropicalis haplotype tree comprising individuals from Marion, Iles Crozet, Gough, and Amsterdam islands, recovered three divergent evolutionary lineages with bootstrap values of 86% and 98%, for two of these lineages, indicating strong genetic structure and independent evolution. Shared haplotypes between Marion and other islands confirmed genetic exchanges, whilst the grouping of Marion and Gough Islands together is indicative of regular migration between these two islands. For A. gazella, the haplotype tree recovered numerous instances of grouping of individuals from Marion and Bouvetøya Islands confirming the hypothesis Bouvetøya is likely source of immigrants to Marion Island. This was further confirmed by low population differentiation between these two islands (FST = 0.062 and ΦST of 0.08). The level of hybridization between these species was low at Marion Island with only one hybrid being detected among the 134 animals for which mtDNA data were generated, corresponding to 0.75%. The same individual was identified as a hybrid, following microsatellite profiling of 146 animals, corresponding to a hybridization estimate of 0.68 %. This hybrid individual was classified phenotypically as A. gazella and genotypically was shown to have A. tropicalis ancestry. This level of hybridization is low compared to the other islands where the two species co-occur. However as the samples used in this study were primarily collected from species-specific sites, this may be an underestimate, and the studies… Advisors/Committee Members: Bastos, Armanda D.S (advisor), Bester, Marthan Nieuwoudt (advisor).

Um dos grandes desafios atuais da pesquisa agrÃcola Ã a produÃÃo de cultivares melhorada de mamoneira, com estabilidade genÃtica, alta qualidade e potencial produtivo. A divergÃncia genÃtica Ã um dos mais importantes parÃmetros avaliados por melhoristas de plantas na fase inicial de um programa de melhoramento genÃtico. Em decorrer disso, o objetivo do presente trabalho foi determinar a diversidade genÃtica atravÃs da caracterizaÃÃo e estimaÃÃo das correlaÃÃes genotÃpica, fenotÃpica e de ambiente entre caracteres de acessos de mamona. O experimento em delineamento em blocos ao acaso, com quinze tratamentos e trÃs repetiÃÃes, foi implantado em Lavras, MG. Os dados foram submetidos Ã anÃlise de variÃncia, obtendo-se as distÃncias genÃticas entre os acessos e com base nessas distÃncias, realizou-se anÃlise de agrupamento e correlaÃÃes entre esses acessos para determinaÃÃo da divergÃncia genÃtica. De acordo com o agrupamento utilizando o mÃtodo de Tocher, houve a formaÃÃo de trÃs grupos distintos para os dados qualitativos. Em relaÃÃo ao agrupamento pelo mÃtodo HierÃrquico do âVizinho Mais PrÃximoâ, houve a formaÃÃo de quatro grupos, recomendando-se os cruzamentos entre acessos superiores pertencentes a grupos diferentes. JÃ em relaÃÃo aos dados quantitativos, houve formaÃÃo de quatro grupos, tanto no mÃtodo de Tocher, quanto no mÃtodo hierÃrquico do âVizinho mais prÃximoâ. Para correlaÃÃes, observou-se que houve correlaÃÃo fenotÃpica e ambiental positiva entre as variÃveis, fornecendo importantes informaÃÃes para o estabelecimento de um plano de melhoramento genÃtico da mamona a partir dos acessos avaliados.

One of the great current challenges of the agricultural research is the production of improved castor bean cultivars with genetic stability, high quality and high-yielding potential. The genetic divergence is one of the most important parameters evaluated by plant breeders in the early phase of a genetic improvement program. Owing to this, the objective of the present work was to determine the genetic diversity through the characterization and estimation of the genotypic, phenotypic and environmental correlation among traits of castor bean accessions. The experiment in a randomized blocks design, with fifteen treatments and three replicates, was established in Lavras, MG, Brazil. The data were submitted to the variance analysis, the genetic distances being obtained among the accessions and on the basis of these distances, clustering analysis and correlations among these accessions for determination of the genetic divergence were performed. According to the clustering by utilizing Tocherâs methods, there was the formation of three distinct clusters for the qualitative data. In relation to the clustering for the hierarchic method of nearest neighbor, there was the formation of four clusters, the crosses among superior accessions belonging to different clusters being recommended. But in relation to the quantitative data, there was the formation of four groups, that is, both in TocherÂs method and in the hierarchical…

A variabilidade genética de 66 colônias de Partamona helleri coletadas em cinco localidades do Estado de Minas Gerais foi estimada utilizando dez locos microssatélites. Baixos níveis de polimorfismos foram detectados, obtendo-se 40% de locos polimórficos e 1,5 alelos/loco. A heterozigosidade média esperada para todas as colônias analisadas foi 0,180 e a heterozigosidade média observada foi de 0,107. As subpopulações analisadas apresentaram forte estruturação, com significativa diferenciação genética (FST = 0,552). A análise de variância molecular (AMOVA) revelou que 81,23% da variabilidade genética total é explicada pela variação existente entre as populações, o que confirma a forte estruturação detectada. A análise de agrupamento de todas as colônias em conjunto, não revelou a formação de grupos correspondentes à origem geográfica das mesmas. Porém, ao agrupar as colônias por localidade, verificou-se que a população de Viçosa mostrou-se mais geneticamente diferente das demais, e que as populações de São Miguel do Anta, Teixeiras e Porto Firme mostraram-se geneticamente mais próximas daquela coletada em Rio Vermelho, do que da população de Viçosa, apesar de ser geograficamente mais distante. Estudos mais detalhados, analisando um maior número de colônias e utilizando primers microssatélites específicos para P. helleri, devem ser realizados a fim de fornecerem dados mais conclusivos sobre a variabilidade genética destas abelhas.

The genetic variability of 66 colonies of Partamona helleri collected in five locations of Minas Gerais state was estimated using ten microsatellites loci. Low levels of polymorphism were detected, getting 40% of polymorphic loci and 1,5 alleles/Iocus. The expected average heterozygosity for all the analyzed colonies was 0.180 and the observed average heterozygosity was 0.107. The analyzed subpopulations were well structured, with significant genetic variation (FST = 0.552). The analysis of molecular variance (AMOVA) revealed that 81.23% of the total genetic variability is explained by variation among populations, what confirms the structure observed. The grouping analysis of the colonies, did not reveal the formation of groups corresponding to their geographic origin. However, when grouping colonies according to localities, it was verified that the population of Viçosa was more genetically different from the others, and that populations of São Miguel do Anta, Teixeiras and Porto Firme were closer to that collected in Rio Vermelho, than to population of Viçosa, although Rio Vermelho was geographically more distant. More detailed studies, analyzing a larger number of colonies and using microsatellites primers specific for P. helleri, must be carried out in order to supply more conclusive information about the genetic variability of these bees.

Melipona rufiventris, Lepeletier, 1836 e M. mondury, Smith, 1863 (Hymenoptera, Apidae) são espécies geneticamente similares, popularmente conhecidas como uruçu amarela. Estudos recentes, utilizando marcadores moleculares mostraram que as populações de uruçu amarela em Minas Gerais formam grupos distintos, sendo M. mondury pertencente à região de Mata Atlântica, M. rufiventris e uma terceira espécie, ainda não identificada aqui denominada de Melipona sp., pertencentes à região do Cerrado. O objetivo deste trabalho foi estudar as relações genéticas entre as populações de uruçu amarela no Estado de Minas Gerais, utilizando-se marcadores moleculares ISSR. Foram utilizadas 79 colônias oriundas de 10 localidades diferentes. Para cada colônia, extraiu-se DNA de um indivíduo e utilizouse nove primers ISSR na amplificação. Para a estimativa da diferenciação genética foram realizadas as seguintes análises: (i) Percentual de locos polimórficos (P) e a estimativa da diversidade genética (He); (ii) Dissimilaridade genética utilizando-se o índice de Dice e o método UPGMA; (iii) Análise de variância molecular e φst. Os resultados obtidos mostraram um elevado polimorfismo em nível molecular entre as colônias estudadas. A análise de agrupamento resultou na formação de três grupos distintos representados pelas populações de M. mondury, M. rufiventris e Melipona sp.. No grupo formado pelas populações de Melipona sp. destacam-se as colônias oriundas de Urucuia - MG por apresentarem maior divergência genética em relação às demais localidades.

Melipona rufiventris, Lepeletier, 1836 and M. mondury, Smith, 1863 (Hymenoptera, Apidae) are species genetically close popularly known as "uruçu amarela". Recent studies, using molecular markers showed that the population of "uruçu amarela" in Minas Gerais form distinct groups. M. mondury comes from the Atlantic Forest region, whereas M. rufiventris and a third species, known as Melipona sp. but not yet identified comes from the biome "Cerrado". The goal of this work was to study the genetic relationships between the population of "uruçu amarela" in the State of Minas Gerais using the ISSR molecular markers. 79 colonies from 10 different locations were used. The extracted DNA was amplified using nine ISSR primers and for the analysis one individual per colony was used. For the estimation of genetic differentiation the following analysis were done: (i) Percentage of polymorphic loci (P) and genetic diversity (ii) Genetic dissimilarity using the index of Dice and the method UPGMA (iii) Analysis of molecular variance (AMOVA) and φst. The findings showed a high polymorphism in molecular level among the colonies studied. In the grouping analysis the formation of three distinct groups, composed by M. mondury, M. rufiventris, Melipona sp.. We observed Melipona sp. the population of Urucuia showed significant genetic divergence in relation to the other samples.

Espécies do complexo Ceratocystis fimbriata sensu lato (s.l.) são importantes patógenos de um grande número de plantas arbóreas e herbáceas, com destaque para a cultura do eucalipto. A doença causada por C. fimbriata, denominada murcha-de-ceratocystis, é considerada emergente e de difícil controle por se tratar de um patógeno vascular e com ampla gama de hospedeiros. A principal forma de controle da doença é feita pelo plantio de material resistente, mas a possível variabilidade na população do patógeno pode comprometer a seleção de genótipos resistentes. Neste trabalho, avaliou-se a variabilidade patogênica de isolados de C. fimbriata obtidos de plantas de Eucalyptus spp. no Brasil. Foram inoculados dez isolados do fungo em dez clones comercias de Eucalyptus spp. O experimento foi realizado em delineamento inteiramente casualizado, em esquema fatorial composto de dois fatores (clone X isolado), com quatro repetições. Aos 60 dias após a inoculação, avaliou-se o comprimento de lesão no lenho em relação a altura da planta (% de tecido doente). Os isolados apresentaram variabilidade patogênica, diferenciando em vários níveis de agressividade. Os isolados ANG1 e PT15 foram os menos agressivos, causando infecções em apenas um clone. Os isolados RM35 e PT12 foram os mais agressivos, sendo que o primeiro foi capaz de infectar oito dos dez clones inoculados. Os demais isolados tiveram valores intermediários e variaram a agressividade de acordo com o clone avaliado. Os clones 386 e A06 foram os mais resistentes, enquanto 1172 e 1288 os mais suscetíveis. Esses clones altamente resistentes e altamente suscetíveis podem ser utilizados como comparadores nos experimentos de inoculação controlada e no campo. O resultado do presente trabalho permite concluir que existe variabilidade patogênica na população de C. fimbriata de Eucalyptus spp. e que os isolados mais agressivos são recomendados para as inoculações artificiais visando a seleção de genótipos resistentes à doença.

Species of the complex Ceratocystis fimbriata sensu lato (sl) are important pathogens of a large number of woody plants and herbs, especially the cultivation of eucalyptus. The disease caused by C. fimbriata, called Ceratocystis wilt, is considered an emerging disease and difficult to control because it is a vascular pathogen with wide host range. The main way for disease control is done by planting resistant material, but the possible variability in the pathogen population may affect the selection of resistant genotypes. In this study, we evaluated the agressivity of isolates of C. fimbriata obtained from Eucalyptus spp. in Brazil. Ten isolates were inoculated in ten commercial clones of Eucalyptus spp. The experiment was conducted in a randomized design in factorial composed of two factors (clone X isolate) with four replications. At 60 days after inoculation, we evaluated the length of lesion in the wood in relation to height (% of diseased tissue). The isolates presented pathogenic variability, differing at various levels of aggressiveness. The ANG1 and…

▼ Since 2000, field soybean plants in the states of Bahia, Goiás, Maranhão, Mato Grosso, Minas Gerais, Paraná and Tocantins have been described with symptoms of soybean stem necrosis disease. The symptoms are varied, some milder other severe. The disease has been associated with Cowpea mild mottle virus (CPMMV, family Betaflexiviridae, genus Carlavirus). This study is aimed at the biological characterization and molecular and genetic analyses of genetic variability of isolates of CPMMV that cause symptoms of stem necrosis in soybean fields of different producing Brazil states. The study was conducted with samples collected in the states of Bahia, Goiás, Maranhão, Mato Grosso, Minas Gerais and Pará. The isolates caused a variety of symptoms in soybean cv. CD206, and mild and severe isolates were observed. The complete genomes of six isolates were sequenced and additionally the partial sequence of another 12 isolates was also determined (ORF2- 3 end). No Brazilian CPMMV isolate, from any host, had been entirely sequenced until now. Biological and molecular characterization showed that the six Brazilian isolates, whose genomes have been completely determined, belong to a new CPMMV strain distinct from that which belongs to the only isolated CPMMV previously sequenced from Ghana in Africa. The ORF1 (RdRp) of these six Brazilian isolates showed values of sequence identity (60-61% to 58-69% for nt and aa), less than that set by the International Committee on Taxonomy of Viruses (ICTV), when they were compared with a Ghanaian CPMMV isolate. ORF5 (CP), however, showed identity values (79% to 95-96% for nt and aa) greater than those established by the ICTV when they were compared with the Ghanaian isolate. Both proteins are used to classify isolates of the genus Carlavirus in the same species. Pairwise comparisons and phylogenetic analysis showed that Brazilian isolates are highly related to each other and distinct from isolates of other species of the genus Carlavirus. The phylogenetic trees constructed with partial sequences of the genomes did not show groupings based on geographic region or collection year, but groupings based on symptoms were observed for trees constructed with partial sequences (ORF2-3 end), ORF2 (TGB1), ORF5 (CP) and ORF6 (NABP). Besides the relationship between isolates CPMMV demonstrated by partial sequencing, there are variations between the Brazilian isolates. Evidence of two possible CPMMV strains were found in Brazil with biological and molecular variations between isolates of both strains. Recombination events were identified in genome of the isolates, and they occurred mainly in the ORF1 region of the polymerase, less frequently in other regions of the genome. With this study it was found that the taxonomic criteria, which define the genus Carlavirus may fail in cases where only a partial sequence is determined: if only the ORF1 had been determined during the study we could propose that our isolates belong to a new species of the genus Carlavirus. In addition, there is clearly the need to… Advisors/Committee Members: Claudine Márcia Carvalho, Gloria Patricia Castillo Urquiza, Poliane Alfenas Zerbini, Fábio Nascimento da Silva, Francisco Murilo Zerbini Júnior.

The genus Begomovirus (family Geminiviridae) contains viral species with ssDNA genomes, affecting dicotyledonous plants and transmitted by the whitefly Bemisia tabaci. Viral diseases caused by begomoviruses are of economic importance due to their adverse effects on the production of tropical and subtropical crops. In Ecuador, despite reports of significant infestations of Bemisia tabaci in the late 1990 s, only very recently has a begomovirus, Tomato leaf deformation virus (ToLDeV, also present in Peru), been reported in tomato. ToLDeV is the first monopartite begomovirus originated in the Americas, and its presence in Ecuador highlights the need for a wider survey of tomatoinfecting begomoviruses in this country. The study of ToLDeV populations may provide insights into the evolution of this monopartite virus and its ongoing adaptation to a new host. Tomato and weed samples were collected in 2010 and 2011 in six provinces of Ecuador, and begomovirus genomes were cloned and sequenced using a rolling-circle amplification-based approach. No begomovirus-positive samples were detected in the provinces of Chimborazo and Galapagos. Most begomovirus-positive tomato samples from the provinces of Guayas, Loja, Manabi and Santa Elena were infected with ToLDeV. One sample from Manabí had a triple infection with ToLDeV, Rhynchosia golden mosaic Yucatan virus (RhGMYuV) and a recombinant isolate between the two. A new begomovirus species was detected in another tomato sample from Manabí. Samples of Rhynchosia sp. from the provinces of Guayas and Manabi were infected by RhGMYuV. Sequences of 67 ToLDeV isolates from tomato were used to identify haplotypes and infer genetic relationships with Peruvian isolates. Two ToLDeV subpopulations (Ecuador and Peru) were well structured and presented minor allelic migration. The lowest haplotype diversity was displayed by the C4 gene for both subpopulations. Genetic variability indices were generally much higher for the Peruvian subpopulation in comparison with the Ecuadorian subpopulation. The C4 gene had the highest mutation frequency in both subpopulations. There was evidence of negative or purifying selection acting on each of the viral genes, thus preserving protein function. Tests of neutrality were significant and negative for the CP, Rep, TrAP and C4 genes of the subpopulation from Ecuador, indicating that it is undergoing expansion. All isolates from Ecuador and one isolate from Peru showed a recombination event encompassing the Rep, TrAP and REn genes and the intergenic region. Together, the results indicate a founder effect acting upon the Ecuadorian ToLDeV subpopulation, which is undergoing rapid expansion and differentiation.

(Genetic structure of Tibouchina papyrus (Pohl) Toledo (pau-papel) in natural areas of Cerrado rupestrian fields). This paper has the aim describe the genetic of variability of Tibouchina papyrus (Pohl) Toledo local populations, from the regions of Serra Dourada and Serra de Pirineus, in Goiás State, Central Brazil. The six RAPD primers generated a total of 147 loci, varying from 23 to 26 per primer. The hierarchical evaluation of genetic variability, performed using an Analysis of Molecular Variance (AMOVA) considering the local populations within the two regions (i.e., Serra dos Pirineus and Serra Dourada), showed an estimate of overall diversity among populations equal to ST=0,3439. The value of divergence between regions ( CT) was equal to 18,96%, so that the variation among local populations within regions was equal to 15,43%. Estimates of gene flow indicates a small number of migrants among local populations per generation. Multivariate analyses (UPGMA and NMDS) indicated that a relationship between genetic and geographical distances exists, which was confirmed by a spatial pattern analysis using Mantel test (r = 0.71; P <0.015 with 1000 random permutations). Thus, this structure was originated from a stochastic neutral model of population differentiation, in which drift within populations is counteracted by short distance gene flow. Despite strong levels of population structure (i.e., high divergence among populations within regions), the diversity observed support the hypothesis that Tibouchina papyrus is a facultative xenogamous species. For conservation ends of germplasm with base in the preliminary results, it can be suggested the collection of seeds of the most possible number of populations, and in the two appraised areas, because each one contains a singular component of the total genetic variation.

O presente trabalho teve como objetivo conhecer a variabilidade genética de populações de Tibouchina papyrus (Pohl) Toledo, provenientes da região de Serra Dourada e Serra dos Pirineus, no Estado de Goiás. Os seis iniciadores RAPD produziram um total de 147 locos, variando entre 23 e 26 por iniciador. A avaliação hierárquica da estruturação da variabilidade genética, realizada pela a AMOVA, considerando a existência de duas regiões (Serra dos Pirineus e Serra Dourada) apresentou uma estimativa de ST=0,3439. O valor do componente entre regiões ( CT) foi igual a 18,96% e a variação entre populações dentro de regiões igual a 15,43%. As estimativas de fluxo gênico indicam a existência de uma baixa proporção de migrantes entre populações. As análises multivariadas (UPGMA e NMDS) indicam que existe uma relação entre distância genética e espaço geográfico, hipótese esta que foi confirmada por uma análise de padrão espacial utilizando o teste de Mantel (r = 0,71; P = 0,015 com 1000 permutações aleatórias).

▼ Cowpea (Vigna unguiculata (L.) Walp.) is an important legume crop commonly used for grains and for fodder in some parts of the world. It is grown in over 65 countries worldwide. In the United States, it is primarily grown in the southern states, with major production areas in Texas and California. A systematic breeding program was initiated at Texas A&M University to identify genetic variability for heat tolerance in cowpea germplasm, and the variability was utilized to develop a RIL (recombinant inbred line) mapping population by crossing a heat-tolerant (GEC) and a heat-susceptible (IT98K- 476-8) parent. The RILs were planted in three field environments – College Station in 2014, and Corpus Christi and Weslaco, Texas in 2015, and in a hot greenhouse to screen for heat tolerance, days to flowering, plant height, and other agronomic traits. The RILs were also genotyped using SNPs markers, and QTLs (quantitative trait loci) were mapped for the phenotypic traits measured. Significant phenotypic variability was identified in cowpea germplasm. Both the selected parents utilized to develop RILs were significantly different for all the measured traits, and transgressive segregation was detected in the RIL population. A genetic linkage map was constructed having 11 linkage groups using genotypic data, and one significant QTL was detected on linkage group 3 (LOD of 2.78 and explained 7.66% of variation) for heat-tolerance visual ratings in Corpus Christi, and another on linkage group 10 (LOD of 3.86 and explained 10.64% of variation) for ratings in the greenhouse. For seed weight per plant (SWT), we have detected two QTLs, one on linkage group 3 (LOD of 7.86 and explained 17.05% of variation) and another on 10 (LOD of 5.07 and explained 11.37% of variation). For number of pods per plant (PODN), three QTLs were detected, one on linkage group 3 (LOD of 11.43 and explained 22.93% of variation) and two on linkage group 10 (first – LOD of 3.34 and explained 5.93% of variation; second – LOD of 4.04 and explained 7.62% of variation) using BLUPs (best linear unbiased predictions).

▼ In this study, hypervariable region I (HVRI) of the mitochondrial DNA (mtDNA) control region, and five microsatellite loci were used to assess genetic variability and the extent of hybridization between the two fur seals (Arctocephalus tropicalis and A. gazella), that occur on Sub-Antarctic Marion Island. Both species were harvested during the 18th and 19th centuries, leading to a reduction in population size and the extinction of A. gazella at some localities. Whilst both species have recovered and are increasing in size, it is not clear to what extent sealing has affected genetic variation, although a more pronounced effect would be expected for A. gazella, given the more intensive harvesting of this species. The current study confirmed this hypothesis and revealed that A. gazella had a nucleotide diversity of 2.9 % whilst for A. tropicalis it was 4.2 %, across the HRVI mtDNA region sequenced. For microsatellite DNA, genetic variation in A. tropicalis was higher than in A. gazella in terms of the total number of alleles detected and the level of heterozygosity (HE=0.875, HO=0.845, mean number of alleles=13.6 and HE=0.799, HO=0.781, mean number of alleles=13, respectively). Diversity in both species is among the highest recorded in pinnipeds to date, and suggests that sealing did not overly affect the levels of genetic variation in these species. In terms of population structure, A. tropicalis show a high level of population structure, as indicated by the ΦST of 0.32 between Marion and Gough Island. Furthermore, the A. tropicalis haplotype tree comprising individuals from Marion, Iles Crozet, Gough, and Amsterdam islands, recovered three divergent evolutionary lineages with bootstrap values of 86% and 98%, for two of these lineages, indicating strong genetic structure and independent evolution. Shared haplotypes between Marion and other islands confirmed genetic exchanges, whilst the grouping of Marion and Gough Islands together is indicative of regular migration between these two islands. For A. gazella, the haplotype tree recovered numerous instances of grouping of individuals from Marion and Bouvetøya Islands confirming the hypothesis Bouvetøya is likely source of immigrants to Marion Island. This was further confirmed by low population differentiation between these two islands (FST = 0.062 and ΦST of 0.08). The level of hybridization between these species was low at Marion Island with only one hybrid being detected among the 134 animals for which mtDNA data were generated, corresponding to 0.75%. The same individual was identified as a hybrid, following microsatellite profiling of 146 animals, corresponding to a hybridization estimate of 0.68 %. This hybrid individual was classified phenotypically as A. gazella and genotypically was shown to have A. tropicalis ancestry. This level of hybridization is low compared to the other islands where the two species co-occur. However as the samples used in this study were primarily collected from species-specific sites, this may be an underestimate, and the studies… Advisors/Committee Members: Bastos, Armanda D.S.

▼ Parathyroid hormone is a vital mediator of bone metabolism and studies have shown that exogenous treatment can enhance the fracture repair process in murine models. Bone remodeling is a complex process that necessitates multiple molecular and cellular interactions that are affected by genetic variations. These differences contribute to both histological and whole organ level differences of fracture healing. This study was performed to determine the effect of genetic variability of fracture healing in mice treated with parathyroid hormone during two time windows. The first window was the first 14-day period post fracture associated with chondrogensis and the second was the day 15 to day 28 post fracture, which is associated with osteogenesis. Three inbred strains of mice A/J (AJ), C57BL/6J (B6), and C3H/HeJ (C3) that have material and structural differences in bone quality were given Femoral shaft fractures and healing was evaluated at different time points post fracture using quantitative real-time polymerase chain reaction (qRT-PCR) and qualitative radiographic analysis. Chondrogenic genes Sox9, ColIIa, aggrecan, and ColXa and osteogenic genes ostrix, osteocalcin, BSP, and DMP1 were examined. The temporal analysis of mRNA expression revealed that PTH treatment given in the first 14 days post fracture enhanced osteogenic and chondrogenic expression in B6 mice, but hindered expression in AJ mice. Treatment with PTH from post fracture day 14 to day 28 greatly affected the osteogenic expression of B6 mice, but had little affect on other animals. Radiographic analysis showed that each strain presents callus formation at approximately day 7 and reaches maximum size at day 21 post fracture. Additionally B6 mice appear with the largest callus and AJ the smallest. Taken together, these results are consistent with past studies in showing that different strains of mice express a unique temporal and mRNA expression pattern of chondrogenic and osteogenic differentiation. Furthermore, these variations affect the biomechanical properties of the fracture callus during bone remodeling.

▼ Groundnut (Arachis hypogaea L,) is one of the major sources of food and income for smallholder farmers in Malawi. It is a valuable food security crop that supplies fats and proteins to the predominantly maize–based Malawian diet. Although, groundnut production is a profitable venture for smallholder farmers in Malawi, its productivity is low averaging 250 – 800 kg/ha as compared to a yield of about 4.0 t/ha obtained at research stations. The decline in productivity of groundnuts is due to several abiotic and biotic constraints that smallholder farmers encounter, among them drought due to inadequate and highly variable rainfall in the country. Information on response of different genotypes to drought stress and the explanation of these variabilities is an important requirement in breeding for drought tolerance improvement in groundnut. The main objectives of the study were: (i) to determine the effect of drought stress on the growth performance of groundnut genotypes with respect to morpho-physiological traits,(ii) to identify the relevant traits related to drought tolerance and their relationship to seed yield under drought stress conditions, (iii) to estimate the relative importance of additive and non-additive gene action in controlling the inheritance of drought tolerance traits under moisture stressed conditions and (iv) to investigate the genetic variation existing among genotypes in relation to morpho-physiological traits related to drought tolerance. Twenty-five genotypes from the International Crops Research Institute for Semi-Arid Tropics (ICRISAT) Malawi were evaluated during 2016/17 under rainfed field condition at the drought-testing site of Ngabu Agricultural Research Station. The results indicated high genotypic coefficient of variation (GCV) coupled with high genetic advance (GA), genetic advance as percent of mean (GAM) and heritability estimates for days to maturity (DM), seed yield (SY), relative water content (RWC), biomass (BM), number of filled pods (FP) and pod yield (PY). Seed yield was highly significant and positively correlated with shelling percentage (SHP), hundred seed weight (HSW), SPAD chlorophyll meter reading (SCMR), days to maturity (DM), biomass (BM), relative water content (RWC) and harvest index (HI). Furthermore, path analysis showed that harvest index, biomass, pod yield, shelling percentage, SPAD chlorophyll meter reading, relative water content and days to maturity had the highest direct and indirect effects on seed yield. General combining ability effects were significant for almost all studied traits indicating the importance of additive gene action. Specific combining ability effects were also significant for days to maturity, seed yield, biomass, harvest index, number of field pod and pod yield indicating importance of non-additive gene action controlling the inheritance of these traits. This suggests that both additive and non-additive gene action were important in controlling the majority of the traits. However, additive gene action was more predominant for all traits… Advisors/Committee Members: Sibiya, Julia. (advisor), Odindo, Alfred Oduor. (advisor).

Mestrado em Engenharia Florestal e dos Recursos Naturais - Instituto Superior de Agronomia

The present work aims at presenting a first assessment of the plant survival on three arboreta, which were installed in Lisbon (Tapada da Ajuda), Sintra (Parque Natural de Sintra-Cascais) and Vila Real (Quinta dos Prados - Universidade de Trás-os-Montes e Alto Douro), as well as the survival analysis and the growth of plants from two provenance trials, one of Quercus robur L., located at Vale de Cavalos – Viseu, and another of Quercus ilex L., located at Herdade do Esporão - Reguengos de Monsaraz. The three arboreta belong to a study with 38 arboreta distributed from Scotland until Portugal (from latitude 37º until longitude 57º north). The arboreta were installed under the project REINFFORCE, with the aim to evaluate how the climate changes affect the Atlantic forest. The arboreta, represented by 35 species, interspecific level, and the provenance trials, intraspecific level, allow us to estimate the behaviour of these genetic materials in different environmental situations and to evaluate their potential use in future reforestation. The results obtained in the provenance trial Quercus robur L. at Vale de Cavalos – Viseu presented a survival rate above 70%. In terms of growth, we only observed one provenance with lower growth compared with other provenances. The results obtained in the provenance trial Quercus ilex L. at Herdade do Esporão - Reguengos de Monsaraz presented a survival rate of 48%. In terms of growth, the provenances from the Iberian Peninsula (Portugal and Spain) presented the lower growth rate. The obtained results are very preliminary. The information about arboreta concerns to the setting up phase (first year) and the information about the provenance trials was obtained only two years after the planting. Nevertheless, our results show variability among the different analysed provenances regarding the studied characteristics.

▼ Coral reef ecosystems worldwide are in decline as a result of climate change and other anthropogenic impacts. Prolonged exposure to extreme temperatures are predicted to occur more frequently in the future, resulting in coral bleaching and/or mortality. Different coral colonies within a species often show variation in both bleaching and mortality when exposed to temperature stress, but whether this is a result of genetic differences in the coral host, or its algal symbiont communities, is not clear. To distinguish these influences, the effect of different temperatures (20, 26, 30 and 32ºC) on four different genotypes of Pocillopora damicornis (identified using microsatellites) containing different Symbiodinium communities (identified using quantitative PCR), was investigated. Corals grew most rapidly at control temperatures (26ºC, p<0.001), but this effect varied in strength across genotypes. Extreme temperatures had a negative effect on growth in three of the four genotypes (p<0.016). There was differential mortality in the highest temperature (32ºC), with genotypes 1 and 3 showing the earliest mortality on day 52, while genotypes 2 and 4 experienced total mortality by day 66. In the 30ºC treatment, mortality occurred on day 80, with genotype 4 having the highest mortality (100%), followed by genotype 2 (67%), 1 (44%) and 3 (7%). Genotype 3 was the only coral to show mortality at the cold temperature (20ºC), with 7% of colonies having total mortality and 78% of colonies having at least some partial mortality. Quantitative PCR analysis of the algal symbionts (Symbiodinium spp.) in these corals revealed genotypes 1, 2 and 4 were initially dominated by Symbiodinium C1b-c, while genotype 3 was dominated by Symbiodinium D1. However, when exposed to 30ºC, all genotypes became dominated by D1 by day 72. All corals experienced a decrease in symbionts at 30ºC. However, the density of C1b-c symbionts decreased by an average of 98% across genotypes 1, 2 and 4 when the temperature was raised to 30ºC, suggesting that the shift to D-dominance is most likely due to the expulsion of C1b-c, with D1 symbionts in genotype 3 decreasing by an average of 61% at this temperature. Exposure to cold temperatures resulted in a large increase in densities of clade C symbionts, with genotype 4 having a 350% increase in the number of symbionts per host cell. Conversely, cold temperatures caused an 80% decrease in D1 symbionts in genotype 3, compared to initial levels. Photochemical efficiency of symbionts also varied across temperatures and coral host genotype. Fv/Fm values for the clade C-hosting genotypes were similar at all temperatures except at 20ºC, where genotype 1 values were significantly lower than those of genotypes 2 and 4 at 20ºC and 26ºC. Genotypes 2 and 4 showed no photochemical response to cold temperatures relative to the control. Clade C symbionts had a strong negative response to high temperatures, with Fv/Fm values significantly lower compared to controls. Fv/Fm values recovered at 30ºC for C1b-c symbionts… Advisors/Committee Members: Andrew C. Baker, Christopher Langdon, Thomas Capo, Daniel J. DiResta.

Кечига (Acipenser ruthenus L., 1758) представља потамодромну јесетарску врсту, која насељава реке у сливовима Црног, Азовског, Каспијског, Балтичког, Белог, Баренцовог и Кара мора. Значајан пад бројности услед излова током XX века довео је до потребе за бољом заштитом, па је на IUCN Црвеној листи угрожених врста, кечига сврстана међу рањиве врсте (VU). Ради испитивања морфолошке и генетичке диференцијације кечиге у средњем и доњем току Дунава, узорковано је 95 јединки из три популације, од којих две из Србије (Нови Кнежевац на Тиси и Бачка Паланка на Дунаву) и једна популација из Румуније (Гринду на Дунаву). Међупопулациона варијабилност спољашње морфологије (промене величине и облика тела и главеног региона) анализирана је применом метода геометријске морфометрије. Уни- и мултиваријатном анализом варијансе утврђено је постојање статистички значајних разлика у величини и облику анализираних морфолошких целина између јединки са различитих локалитета. Канонијска дискриминантна анализа (CVA) укупне варијабилности облика, код латералног и вентралног приказа тела и латералног приказа главеног региона, показала је да се по првој оси раздваја популација из Румуније од популација из Србије. На нивоу вентралне перспективе тела, као и на нивоу обе перспективе главе утврђен је статистички значајан ефекат алометрије на укупну варијабилност облика. На основу CVA неалометријске компоненте варијабилности облика тела (вентрална перспектива) и главеног региона (латерална и вентрална перспектива) утврђено је да по првој оси постоји раздвајање јединки из Румуније у односу на јединке из Србије. Такође, CVA неалометријске компоненте варијабилности облика главеног региона у обе перспективе указује на могућност да кечиге из Србије (нарочито оне из Тисе) одговарају краткорилој, док кечиге из Румуније одговарају дугорилој форми. Употребом митохондријске ДНК и микросателита као молекуларно-генетичких маркера, детектован је значајан ниво диверзитета (13 хаплотипова, просечан број алела по локусу и популацији 4.3 – 4.9 и добијена хетерозиготност 0.577 – 0.648) али не и јасна диференцијација између популација...
