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.

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.

The diversity of life forms around us is astounding: a walk in the woods, or even down the street, shows us organisms of different morphologies: two legs, four legs, wings; different capacity of interaction with our environment: plants photosynthesizing while bacteria break down our garbage. How can life take on so many forms? While there is some increase of genes when comparing the most simple eukaryotes to the most complex ones it is clear that organism complexity is not the result of the number of genes. Therefore is has been postulated that the complexity of an organism arises from the complexity of its gene regulation, rather than the number of genes. This regulation must come then from the non-gene part of the genome. We now know that genes constitute but a small portion of genomes, (about 5% of the human genome). The advent of whole-genome sequencing has enabled us to get a more complete picture of what is in a genome, and with that has come the surprise that a significant part of all genomes characterized is constituted of transposable elements (TEs). Transposable elements are mobile genetic sequences, meaning that they have the capacity to change their position within the genome of a single cell. The goal of my dissertation has been to investigate the role of TEs in plants and their impact on gene and genome evolution. For this I have taken two approaches. The first is a study in the newly sequenced genome of Cucumis melo, an important crop plant in Spain. In the context of this project I have characterized the transposon landscape in the genome, and identified TE related polymorphisms between seven different varieties. This project has of interest the fact that this is an important plant for agriculture and domestication is a particularly relevant evolutionary context in which to study the impact of transposons, as the lines analyzed come from different geographic and selection backgrounds. In the context of this project I have developed a pipeline for genome annotation, and a software for detection of polymorphisms using next-generation paired-end sequencing data. This yielded insight into the dynamics of transposon evolution in this genome, and the selective forces that have shaped the transposon landscape. To our knowledge this is the first analysis that uses polymorphic TEs to investigate differential chromosomal distribution of recent and old transposons, and thus revealing at an intra-species scale the timeline of selection. The results obtained are promising for studying the contribution of mobile elements to the evolution of two genetically similar yet phenotypically different cultivated varieties. In order to study the impact of transposition on gene regulation, I investigated MITE families which have amplified a transciption factor binding site (TF BS) in the model plant Arabidopsis thaliana. This project focuses on the potential impact on gene regulation networks of the redistribution of this TFBS, a phenomenon that has been described for various master TF in animals but not yet to my knowledge in plants. This study combines in silico analysis with molecular data such as microarrays and ChIP, and is a striking example of one of the many manners in which TEs can impact gene regulation. The work in this dissertation highlights the contradictory nature of transposable elements: on one hand, they are invasive, and on the other, are the source of essential innovations. Here we provide insight as to the functions they play in plant 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.

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.
