Download or read book Genetic Diversity in Plants written by Mahmut Caliskan and published by BoD – Books on Demand. This book was released on 2012-03-14 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic diversity is of fundamental importance in the continuity of a species as it provides the necessary adaptation to the prevailing biotic and abiotic environmental conditions, and enables change in the genetic composition to cope with changes in the environment. Genetic Diversity in Plants presents chapters revealing the magnitude of genetic variation existing in plant populations. The increasing availability of PCR-based molecular markers allows the detailed analyses and evaluation of genetic diversity in plants and also, the detection of genes influencing economically important traits. The purpose of the book is to provide a glimpse into the dynamic process of genetic variation by presenting the thoughts of scientists who are engaged in the generation of new ideas and techniques employed for the assessment of genetic diversity, often from very different perspectives. The book should prove useful to students, researchers, and experts in the area of conservation biology, genetic diversity, and molecular biology.

This book was released on 2001-11-30 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The lack of discussion of the life histories of modular organisms is the weakness of this book that I most regret. . . . Modular organisms are different. " S. C. Steams: The Evolution of Life Histories (1992) Life-history theory endeavours to increase our understanding of the processe,s whereby the broad features of the life cycles of organisms, such as the timing and magnitude of reproduction, have evolved. Although reproductive traits have dominated as study objects due to their immediate importance for evolutionary success, much work has also been conducted on patterns of development, growth and senescence, as well as on the shifts in resource allocation related to these processes. The basic axiom of life-history theory is that patterns of life histories, such as reproductive traits, are subject to evolutionary explanation. This idea can be traced back at least as far as Darwin's Origin of Species (1859). In his discussion of plant domestication, Darwin wrote: "I cannot doubt that the continued selection of slight variations, either in the leaves, the flowers, or the fruit, will produce races differing from each other chiefly in these characters". Darwin was impressed by the success of plant breeders in moulding the growth and reproductive parameters of cultivated plants, and believed that natural selection could have a similar impact in natural populations.
Download or read book Plant Variation and Evolution written by David Briggs and published by Cambridge University Press. This book was released on 2016-06-30 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are in the midst of a biological revolution. Molecular tools are now providing new means of critically testing hypotheses and models of microevolution in populations of wild, cultivated, weedy and feral plants. They are also offering the opportunity for significant progress in the investigation of long-term evolution of flowering plants, as part of molecular phylogenetic studies of the Tree of Life. This long-awaited fourth edition, fully revised by David Briggs, reflects new insights provided by molecular investigations and advances in computer science. Briggs considers the implications of these for our understanding of the evolution of flowering plants, as well as the potential for future advances. Numerous new sections on important topics such as the evolutionary impact of human activities, taxonomic challenges, gene flow and distribution, hybridisation, speciation and extinction, conservation and the molecular genetic basis of breeding systems will ensure that this remains a classic text for both undergraduate and graduate students in the field.

Book excerpt: This book describes the experimental and analytical methodologies available for the genetical analysis of qualitative, quasi-quantitative and quantitative traits and its applications in practical plant breeding and evolution. Models for studying quantitative genetic variation following Birmingham and Edinburgh notations are described. The statistics used is simple and systematic so that the reader will have no difficulty in solving problems in plant genetics. It describes the genetic principles and provides breeding procedures underlying various breeding methods for manipulating qualitative, quasi-quantitative and quantitative traits. It takes into account the latest developments in breeding methodologies including dihaiploidy and apomixis, applications of tissue culture for plant breeding use, genetic engineering for production of transgenics and hybrids, and molecular marker technologies in the analysis of quantitative trait loci, marker assisted selection, evolution and conservation of genetic resources. This book will be useful for undergraduates, postgraduates, teachers and researchers working in the field of genetics and plant breeding.

This book was released on 2000-05-04 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combining insights from observation, experimentation, and theory, The Origin, Expansion, and Demise of Plant Species offers a broad overview of species as dynamic entities that arise, have unique evolutionary histories, and ultimately go extinct. It begins with a review of species concepts and the exposition of a new concept; it then addresses plant speciation, the expansion of species from their narrow centers of origin, intraspecific differentiation, and contact zones between differentiated population systems. Special attention is given to the breakdown of cohesion among populations by reproductive and spatial barriers. Also, the ecological and genetic properties of small populations and fragmented population systems are discussed with a focus on the role of hybridization in the demise of species. It ends with an exploration of the longevity of species and the tempo of diversification, contrasting different groups of plants in these respects as well as in rates of chromosomal differentiation. This book provides a new synthesis of evolutionary biology and ecology. It examines species from their origins, then follows them through their expansion, differentiation and loss of cohesion, and decline and extinction. The stages in the lives of species are viewed through ecological and genetic theory, and topics typically addressed independently are woven into a continuous fabric. As the first synthetic treatment of the stages through which plant species pass, this book is very useful for botanists, evolutionary biologists, conservation biologists, as well as all curious students of the biological sciences.

Download or read book Plant Density Effects on Genetic Variation and Dispersal for Two Co occurring Persoonia Species written by Jessica Anne Stingemore and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] Genetic variation is spatially structured at different scales, such as population, subpopulation or among neighbouring individuals. This spatial genetic structure is typically a product of environmental influences and ecological factors affecting reproduction and dispersal are likely to be particularly important in determining genetic structure. Consequently, information about ecological factors such as plant density, pollen dispersal and seed dispersal represent important processes for conservation managers. In this thesis, molecular markers are applied to better understand patterns and processes effecting genetic variation in two co-occurring tree congeners, chosen because they have densities that are typically three orders of magnitude different, yet near identical life-history parameters. Persoonia longifolia occurs in the southwest jarrah (Eucalyptus marginata) forest of Western Australia in relatively high densities, while P. elliptica occurs largely at very low densities. To develop molecular markers for these two broadly distributed tree species, microsatellite markers developed for the southeast Australian P. mollis were initially screened for amplification in individuals of both P. elliptica and P. longifolia. This cross amplification of primers was unsuccessful for both study species. Therefore, microsatellite enriched libraries and 454 GS-FLX shotgun sequencing were employed to identify nine microsatellite loci for P. elliptica (one 454; eight cloning) and six loci for P. longifolia (three 454; three cloning). The microsatellites identified in this study enabled the examination of spatial structuring of genetic diversity and pollen and seed dispersal characteristics in P. elliptica and P. longifolia.
Download or read book Landscape Genetics written by Niko Balkenhol and published by John Wiley & Sons. This book was released on 2015-11-09 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: LANDSCAPE GENETICS: CONCEPTS, METHODS, APPLICATIONS LANDSCAPE GENETICS: CONCEPTS, METHODS, APPLICATIONS Edited by Niko Balkenhol, Samuel A. Cushman, Andrew T. Storfer, Lisette P. Waits Landscape genetics is an exciting and rapidly growing field, melding methods and theory from landscape ecology and population genetics to address some of the most challenging and urgent ecological and evolutionary topics of our time. Landscape genetic approaches now enable researchers to study in detail how environmental complexity in space and time affect gene flow, genetic drift, and local adaptation. However, learning about the concepts and methods underlying the field remains challenging due to the highly interdisciplinary nature of the field, which relies on topics that have traditionally been treated separately in classes and textbooks. In this edited volume, some of the leading experts in landscape genetics provide the first comprehensive introduction to underlying concepts, commonly used methods, and current and future applications of landscape genetics. Consistent with the interdisciplinary nature of the field, the book includes textbook-like chapters that synthesize fundamental concepts and methods underlying landscape genetics (Part 1), chapters on advanced topics that deserve a more in-depth treatment (Part 2), and chapters illustrating the use of concepts and methods in empirical applications (Part 3). Aimed at beginning landscape geneticists and experienced researchers alike, this book will be helpful for all scientists and practitioners interested in learning, teaching, and applying landscape genetics.
