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.

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.

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.

The centromere is an essential structure on all eukaryotic chromosomes that allows the equipartition of chromosomes during mitotic and meiotic cell divisions. Since its cytogenetic recognition as a constructed part of a chromosome many decades ago, great advances have been made in ourunderstanding of this intriguing structure, especially at the molecular level. This book brings together all available information on the centromere. It covers in details the DNA and protein components of this structure, and their individual functions, in species as diverse as budding and fissionyeasts, nematodes, Drosophila, mice, and humans; newly discovered roles of the centromere in marshalling "passenger" proteins; important emerging concepts such as latent centromeres and epigenetic factors; cytogenetic problems associated with centromere abnormalities; and practical application ofcentromere studies, such as in the construction of human artificial chromosomes for gene therapy. Supported by ample illustrations, the book is written with sufficient simplicity and detail to suit both specialist and non-specialist scholars. It is the first book on the subject

Many fundamental discoveries concerning epigenetics and the elucidation of mechanisms of epigenetic regulation have developed from studies performed in plants. In Plant Epigenetics and Epigenomics: Methods and Protocols, leading scientists in the epigenetics field describe comprehensive techniques that have been developed to understand the plant epigenetic landscape. These include recently developed methods and techniques for analysis of epigenetically regulated traits, such as flowering time, transposon activation, genomic imprinting and genome dosage effects. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoidance of known pitfalls. Authoritative and practical, Plant Epigenetics and Epigenomics: Methods and Protocols seek to aid scientists in the further study of plant epigenetic phenomena using advanced contemporary methods.

This book discusses advances in our understanding of the structure and function of the maize genome since publication of the original B73 reference genome in 2009, and the progress in translating this knowledge into basic biology and trait improvement. Maize is an extremely important crop, providing a large proportion of the world’s human caloric intake and animal feed, and serving as a model species for basic and applied research. The exceptionally high level of genetic diversity within maize presents opportunities and challenges in all aspects of maize genetics, from sequencing and genotyping to linking genotypes to phenotypes. Topics covered in this timely book range from (i) genome sequencing and genotyping techniques, (ii) genome features such as centromeres and epigenetic regulation, (iii) tools and resources available for trait genomics, to (iv) applications of allele mining and genomics-assisted breeding. This book is a valuable resource for researchers and students interested in maize genetics and genomics.
