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 volume gives an overview on mobile DNA and how such contradiction to the obligatory stability of genomes can be understood. Obviously, an understanding can only be achieved by cutting deeply into the evolutionary history of life.

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.”

Recent major advances in the field of comparative genomics and cytogenomics of plants, particularly associated with the completion of ambitious genome projects, have uncovered astonishing facets of the architecture and evolutionary history of plant genomes. The aim of this book was to review these recent developments as well as their implications in our understanding of the mechanisms which drive plant diversity. New insights into the evolution of gene functions, gene families and genome size are presented, with particular emphasis on the evolutionary impact of polyploidization and transposable elements. Knowledge on the structure and evolution of plant sex chromosomes, centromeres and microRNAs is reviewed and updated. Taken together, the contributions by internationally recognized experts present a panoramic overview of the structural features and evolutionary dynamics of plant genomes.This volume of Genome Dynamics will provide researchers, teachers and students in the fields of biology and agronomy with a valuable source of current knowledge on plant genomes.

In this timely new 2-volume treatise, experts from around the world have banded together to produce a first-of-its-kind synopsis of the exciting and fast moving field of plant evolutionary genomics. In Volume I of Plant Genome Diversity, an update is provided on what we have learned from plant genome sequencing projects. This is followed by more focused chapters on the various genomic “residents” of plant genomes, including transposable elements, centromeres, small RNAs, and the evolutionary dynamics of genes and non-coding sequences. Attention is drawn to advances in our understanding of plant mitochondrial and plastid genomes, as well as the significance of duplication in genic evolution and the non-independent evolution among sequences in plant genomes. Finally, Volume I provides an introduction to the vibrant new frontier of plant epigenomics, describing the current state of our knowledge and the evolutionary implications of the epigenomic landscape.

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.

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.

This text deals with the evolution of transposable elements (TE). Two main aspects are presented. First, after a description of the main types of elements, their life and death within a species, including regulation of transposition, and their distribution in natural populations and on chromosomes are discussed. Then, the impact of TEs on the host genomes, the putative relationship between environment and transposition rates lead to a discussion of the interaction (or coevolution) between TEs and their host. Second, these results introduce the analysis of the phylogenies of TEs and their interpretations, according to different models i.e. horizontal versus vertical transmission. Finally, the questions of the origin and of the general evolution of TEs is raised from the comparison of conserved regions like reverse transcriptase or transposase-integrase domains.
