Retrotransposable elements are major constituents of genomes. These mobile DNA sequences can disrupt genes, induce genomic rearrangements, influence gene expression and mobilize various types of non-autonomous sequences. Their genomic status is still controversial and an object of intense debate in the scientific community. On the one hand, retrotransposable elements are frequently considered as genome parasites or as 'junk DNA' causing genetic diseases and evolving as retroviruses. On the other hand, mobile DNA and transposition are driving forces of genome evolution. Many regulatory and coding sequences contain parts of transposable elements that are required for proper expression and function of resident genes and proteins. Some mobile sequences have been domesticated by the host and play important cellular roles. Valuable reading for researchers and teachers involved in genetics, genome structure and evolution, this publication updates the current knowledge on retrotransposition and retrotransposable elements and their impact on gene function and genome evolution.

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.

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.

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.”

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.

This Research Topic is part of the Mobile Elements and Plant Genome Evolution, Comparative Analyses and Computational Tools series: Mobile Elements and Plant Genome Evolution, Comparative Analyses and Computational Tools Transposable elements are very common mobile genetic elements that are composed of several classes and make up the majority of eukaryotic genomes. The movement and accumulation of mobile genetic elements have been a major force in the formation of the genes and genomes of nearly all organisms. As dispersed and ubiquitous mobile elements, their life cycle of replicative transposition leads to genome rearrangements affecting cellular function. Transposable elements are important drivers of species diversity, and they exhibit great variety in structure, size, and mechanisms of transposition, making them important putative actors in genome evolution.

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, which are 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. Providing a systematic interpretation of protocols designed to characterize TEs and their biotechnological roles, the volume explores TEs in plant development, their architecture, their epigenetic regulation, their use in DNA repair, their evolution and speciation, while also highlighting their importance in the approaching epoch of climate change. The volume begins with introduction of transposable elements, covering their classification and transposition. It delves into protocols designed to characterize TEs and their biotechnological applications. The book includes 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.

In the summer of 1992 a distinguished group of molecular, population and evolutionary geneticists assembled on the campus of the University of Georgia in Athens, USA to discuss the relevance of their research to the role played by transposable elements (TEs) in evolution. The meeting consisted of a series of informal discussions of issues brought up in papers written by the participants and distributed among them prior to the meeting. These papers and the transcripts of the ensuing discussions are presented in this volume.
