Download or read book Quercus Genetics written by Mary V Ashley and published by Mdpi AG. This book was released on 2022-01-14 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genus Quercus (Quercus, Fagaceae) comprises more than 400 species distributed throughout the northern hemisphere. While the highest oak diversity occurs in American and Asia, European species are also widespread. Oaks are ecological dominants of many temperate forests, and evergreen species are major components of Mediterranean and subtropical woodlands. They provide important ecosystem services and valuable timber. Oak species exhibit high genetic diversity, and this diversity has provided a wealth of information regarding oak ecology and evolution. Recent genetic and genomic studies of oaks have unraveled their evolutionary origins, history, and past radiations. Genetic approaches have also been applied to learn about more recent events, such as range expansions and contractions occurring at northern latitudes.

This book was released on 2006-08-29 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study is the first documentation on genetic variation and hybridization within such a complex natural community of oak species (Quercus spp.). It is also the first report of the use of microsatellite analysis in Q. frainetto, a relatively widespread species in the Balkan region and in southern Italy. Multiple morphological characters as well as three types of genetic markers were used to discriminate between species and their hybrids. In addition, paternity analysis was performed to retrace the patterns of contemporary gene flow and hybridization within this species-rich oak community. Both chloroplast and nuclear genetic markers discriminated clearly between Q. cerris and the group consisting of the four other white oak species, which is consistent with the taxonomical scheme. In contrast, within the white oak group, the species shared the most common chloroplast haplotypes which might be interpreted as an evidence for interspecific gene flow in a relatively recent past. Both categories of nuclear markers, isozymes and microsatellites, have revealed high levels of genetic variation within species. The amount of genetic differentiation estimated across all loci using nuclear markers was always significant (P

This book was released on 2011-08-27 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild crop relatives are now playing a significant part in the elucidation and improvement of the genomes of their cultivated counterparts. This work includes comprehensive examinations of the status, origin, distribution, morphology, cytology, genetic diversity and available genetic and genomic resources of numerous wild crop relatives, as well as of their evolution and phylogenetic relationship. Further topics include their role as model plants, genetic erosion and conservation efforts, and their domestication for the purposes of bioenergy, phytomedicines, nutraceuticals and phytoremediation. Wild Crop Relatives: Genomic and Breeding Resources comprises 10 volumes on Cereals, Millets and Grasses, Oilseeds, Legume Crops and Forages, Vegetables, Temperate Fruits, Tropical and Subtropical Fruits, Industrial Crops, Plantation and Ornamental Crops, and Forest Trees. It contains 125 chapters written by nearly 400 well-known authors from about 40 countries.

This book was released on 2013-04-17 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Holm oak (Quercus ilex L.) forests and woodlands have been considered as a paradigm for Mediterranean terrestrial ecosystems. In the western part of the Mediterranean Basin, these forests and woodlands occupy large areas and thus play a very important role in the landscape. A number of research projects from the Centre d'Ecologie Fonctionnelle et Evolutive (CEFE), the Centre de Recerca Ecológica i Aplicacions Forestals (CREAF), and from many other laboratories are currently focusing on Q. ilex ecosystems, and a number of problems have appeared concerning not only basic knowledge but also management aspects. For this reason, the CEFE and the CREAF decided to jointly organize the workshop on Quercus ilex L. Ecosystems, which was held in Montpellier and Barcelona in September 1990. The present volume consists of a selection of papers presented during the workshop and other papers contributed after the workshop. The papers are divided into five sections: Biogeography and History; Structure, Productivity and Dynamics; Water Relationships; Nutrient Cycling; and Management.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characterizing the genomic basis of climate adaptation is essential both for understanding the process of evolution and for conserving populations under climate change. Here, I use several methods to investigate the genomic basis of adaptation across oak species and populations. In Chapter 1, we compared the gene expression response to a simulated drought stress across six oak species, two species from each of the three taxonomic sections of Quercus in California, which varied in their drought tolerance. We found that drought tolerant species had a less plastic response to leaf drying, suggesting that phenotypic traits and non-plastic patterns of gene expression contribute to their drought tolerance more than plasticity. We also found that the two deciduous trees, which were the most drought sensitive species, responded to drying with 22% of the same genes, indicating these responses had evolved in parallel across distantly related clades. In Chapter 2, we used whole-genome sequencing to characterize the rangewide genetic structure of a rare island endemic oak species, Quercus tomentella, from the California Channel Islands and Guadalupe Island in Mexico. We found evidence for widespread hybridization with a related oak species, isolation of the Guadalupe Island trees, and some gene flow among the California islands that is likely mediated by wind pollination. We also identified putatively adaptive SNPs that were associated with climate variables, compared the spatial patterns of neutral SNPs and candidate SNPs, and used this information to make recommendations for choosing seed sources for restoration projects in the light of climate change. In Chapter 3, we characterized the heat stress response across species and populations. We performed a heat wave experiment and compared the gene expression responses among three oak species and two populations within each species, one from a southern, warmer site and one from a northern, cooler site. We found shared responses to heat stress among all species and populations, including the responses of individual genes as well as genes with related functions. We found limited evidence of differences in stress response among populations, suggesting a lack of local adaptation in the plastic heat stress response.
