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.
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.

Available in PDF, EPUB and Kindle. Book excerpt: Tropical climates, which occur between 23°30'N and S latitude (Jacob 1988), encompass a wide variety of plant communities (Hartshorn 1983, 1988), many of which are diverse in their woody floras. Within this geographic region, temperature and the amount and seasonality of rainfall define habitat types (UNESCO 1978). The F AO has estimated that there 1 are about 19 million km of potentially forested area in the global tropics, of which 58% were estimated to still be in closed forest in the mid-1970s (Sommers 1976; UNESCO 1978). Of this potentially forested region, 42% is categorized as dry forest lifezone, 33% is tropical moist forest, and 25% is wet or rain forest (Lugo 1988). The species diversity of these tropical habitats is very high. Raven (1976, in Mooney 1988) estimated that 65% of the 250,000 or more plant species of the earth are found in tropical regions. Of this floristic assemblage, a large fraction are woody species. In the well-collected tropical moist forest of Barro Colorado Island, Panama, 39. 7% (481 of 1212 species) of the native phanerogams are woody, arborescent species (Croat 1978). Another 21. 9% are woody vines and lianas. Southeast Asian Dipterocarp forests may contain 120-200 species of trees per hectare (Whitmore 1984), and recent surveys in upper Amazonia re corded from 89 to 283 woody species ~ 10 cm dbh per hectare (Gentry 1988). Tropical communities thus represent a global woody flora of significant scope.

This book was released on 2017-12-12 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 500 species distributed all around the Northern Hemisphere, the genus Quercus L. is a dominant element of a wide variety of habitats including temperate, tropical, subtropical and mediterranean forests and woodlands. As the fossil record reflects, oaks were usual from the Oligocene onwards, showing the high ability of the genus to colonize new and different habitats. Such diversity and ecological amplitude makes genus Quercus an excellent framework for comparative ecophysiological studies, allowing the analysis of many mechanisms that are found in different oaks at different level (leaf or stem). The combination of several morphological and physiological attributes defines the existence of different functional types within the genus, which are characteristic of specific phytoclimates. From a landscape perspective, oak forests and woodlands are threatened by many factors that can compromise their future: a limited regeneration, massive decline processes, mostly triggered by adverse climatic events or the competence with other broad-leaved trees and conifer species. The knowledge of all these facts can allow for a better management of the oak forests in the future.
Download or read book Low Intensity Breeding of Native Forest Trees in Argentina written by Mario J. Pastorino and published by Springer Nature. This book was released on 2020-11-18 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global climate change requires the development of programs that consider the active restoration of degraded forests and the use of native trees in afforestation to preserve the natural environment. International commitments like the UN REDD program, the Montréal Process and the Convention on Biological Diversity call for the breeding of species rarely contemplated by large industrial companies. Low-intensity breeding is the most rational strategy for those species: simple but robust, and not dependent on continuously increasing funding, and therefore effective even with a relatively small budget. It commonly focuses on high genetic diversity rather than improving economic traits and adaptability rather than productivity. Controlled crosses with full pedigrees typical of high-intensity breeding are replaced by open pollination. This book presents state-of-the-art breeding strategies from the last two decades for several forest tree species of prime importance in the natural forests of Argentina. They are distributed in the three main forestry ecoregions of the country: the subtropical dry forest (Chaco), the subtropical rain forests (Yungas and Alto Paraná rainforests) and the temperate forests of Patagonia. The book also discusses the genetic patterns of the selected species defined using genetic markers together with the analysis of the variation in quantitative traits. Further, it examines the crucial features of their reproductive biology, such as the mating system and gene flow and describes the current breeding programs. Lastly, it presents the latest developments in genetic resources and their emerging applications, concluding with some reflections and perspectives related to the conditioning imposed by climate change.
