Book Description
Once considered merely `selfish' or `parasitic' DNA, transposable elements are today recognized as being of major biological significance. Not only are these elements a major source of mutation, they have contributed both directly and indirectly to the evolution of genome structure and function. On October 8-10, 1999, 100 molecular biologists and evolutionists representing 11 countries met on the campus of The University of Georgia in Athens for the inaugural Georgia Genetics Symposium. The topics of presentations ranged from how the elements themselves have evolved to the impact transposable elements have had on the evolution of their host genomes. The papers in this volume therefore represent state-of-the-art thinking, by leading world experts in the field, on the evolutionary significance of transposable elements.

Pages : 366

Book Description
During the last 50 years, the perception oftransposable elements (TEs) has changed considerably from selfish DNA to sequences that may contribute significantly to genome function and evolution. The recent increased interest in TEs is based on the realization that they are a major genetic component (at least 10--20%) of all organisms and a major contributor to the mutation process. It is currently estimated that 70--80% of spontaneous mutations are the result of TE-mediated insertions, deletions, or chromosomal rearrangements. Thus, it seems at least plausible that TEs may playa significant role in the adaptation and evolution of natural populations and species. The ubiquity of TEs suggests that they are an old component of genomes which have been vertically transmitted through generations over evolutionary time. However, detailed analyses carried out over the last 20 years have revealed several unusual features of TE evolution: (i) TEs can be horizontally transferred between species; (ii) TE evolutionary rates can be dramatically increased by specific inactivation processes, such as the RIP (Repeat Induced Point mutation) mechanism in fungi; (iii) TEs can influence the regulation of other TEs by insertion or deletion; (iv) different classes of TEs in even distantly related species can be remarkably similar in both structure and function.

Mobile Genetic Elements

Languages : en
Pages : 295

Book Description
Leading experts describe in step-by-step detail their most productive transposon-based methods and strategies for studying genome structure, function, and evolution. These readily reproducible techniques cover a wide range, including mutagenesis, transgenesis, gene silencing, and molecular systematics. Among the highlights are a series of DNA hybridization methods for analyzing the distribution and dynamics of mobile DNA at the hosts' genomic level, techniques for studying LTR retrotransposons in heterologous host systems, and mutagenesis protocols for investigating gene functions in a broad range of organisms. These cutting-edge methods offer investigators powerful genetic tools for dissecting the function of a specific gene, elaborating on the mechanisms leading to genetic change and diversity, and studying the evolutionary impact of mobile DNA on the biology and evolution of organisms.

Plant Transposable Elements

Publisher: Springer Science & Business Media
ISBN: 3642318428
Category : Science
Languages : en
Pages : 338

Book Description
Transposable elements are short lengths of DNA with the capacity to move between different points within a genome. This process can affect the function of genes at or near the insertion site. The present book gives an overview of the impact of transposable elements on plant genomes and explains how to recognize and study transposable elements, e.g. by using state-of-the-art strategies like “new generation sequencing.” Moreover, the impact of transposable elements on plant genome structure and function is reviewed in detail, and also illustrated in examples and case studies. The book is intended both for readers familiar with the field and for newcomers. With large-scale sequencing becoming increasingly available, more and more people will come across transposable element sequences in their data, and this volume will hopefully help to convince them that they are not just “junk DNA.”

Plant Transposons and Genome Dynamics in Evolution

Plant Transposons and Genome Dynamics in Evolution PDF Author: Nina V. Fedoroff
Publisher: John Wiley & Sons
ISBN: 1118500105
Category : Science
Languages : en
Pages : 240

Book Description
The transposable genetic elements, or transposons, as they are now known, have had a tumultuous history. Discovered in the mid-20th century by Barbara McClintock, they were initially received with puzzlement. When their genomic abundance began to be apparent, they were categorized as "junk DNA" and acquired the label of parasites. Expanding understanding of gene and genome organization has revealed the profound extent of their impact on both. Plant Transposons and Genome Dynamics in Evolution captures and distills the voluminous research literature on plant transposable elements and seeks to assemble the big picture of how transposons shape gene structure and regulation, as well as how they sculpt genomes in evolution. Individual chapters provide concise overviews of the many flavors of plant transposons and of their roles in gene creation, gene regulation, development, genome evolution, and organismal speciation, as well as of their epigenetic regulation. This volume is essential reading for anyone working in plant genetics, epigenetics, or evolutionary biology.

Book Description
"This new volume provides an up-to-date understanding of the numerous classes of plant transposable elements, the mobile units of DNA that comprise large portions of plant genomes, an important contributor for gene and genome evolution. Transposable elements (TEs) are major components of large plant genomes and main drivers of genome evolution, known to produce a wide variety of changes in plant gene expression and function. This book, Plant Transposable Elements: Biology and Biotechnology, provides a systematic interpretation of protocols designed to characterize TEs and their biotechnological roles. The chapters explore the role of TEs in plant development, their architecture, their epigenetic regulation, their use in DNA repair, their evolution and speciation, while highlighting their importance in the approaching epoch of climate change. It discusses the applications of the transposons in genome editing and their biology, classification, structure, functions, and evolution. The volume begins with introduction of transposable elements (TEs), covering their introduction, classification, and transposition. It delves into protocols designed to characterize TEs and their biotechnological applications. This section looks at computational approaches for prediction and analysis, retro-transposon capture sequencing, and more. The section on transposon biology focuses on its role in plant development and as natural genetic engineers of genome mutation, evolution, and speciation. The book looks further into transposon applications in genome editing, exploring tagging and mutagenesis, genome engineering, and more. The last chapter uses the example of Oryza sativa to elucidate on the classification, structure, function, and evolution of transposable elements. This comprehensive volume is a valuable comprehensive resource for researchers, faculty, and students in biology, biotechnology, genetics, and botany and plant science."--
