The organization of genomes in higher organisms has been studied extensively in recent years. With current achievements in gene engineering, it seems quite realistic that they will be specifically modified in the nearest future to produce new, economi cally valuable forms of animals and plants. The success of these experiments will depend greatly on the level of our knowledge of the structural features of plant and animal DNAs. Comparative studies of DNA from different organisms began with discovery of its genetic significance in the late 1950's. A few years later it was found that nuclear DNA, the main storage of genetic information,~an consist of several fractions differ ing in some physical and chemical properties. Along with the "major" DNA, bearing the main load during the genotype functioning, the so-called satellite DNAs were discovered. T. G. Beridze, the author of this book, is one of the pioneers in the study of these extraordinary DNAs. The results of his experiments with plant satellite DNAs have essentially influenced the formation of our current ideas on their structure and prop erties.

This book gives a comprehensive overview of the unique roles that non-coding repetitive elements such as satellite DNAs play in different physiological and evolutionary processes. It presents the gene-regulatory aspect of satellite DNAs in different model systems including mammals, insects and plants. In addition, evolutionary aspects of activation of satellite DNAs in terms of transcription and proliferation are highlighted, revealing the role of satellite DNAs in the process of adaptation to changing environment and in the speciation process. Finally, the book discusses satellite DNA activation during pathological transformation and the mechanisms by which they affect disease progression. Namely, some satellite DNAs promote the oncogenic processes by affecting genome epigenetic regulation as well as genome integrity. Readers get a full overview of the latest research on satellite DNA.

The experimental data that have been generated using new molecular techniques associated with the completion of genome projects have changed our perception of the structural features, functional implications and evolutionary dynamics of repetitive DNA sequences. This volume of Genome Dynamics provides a valuable update on recent developments in research into multigene families, centromeres, telomeres, microsatellite DNA, satellite DNA, and transposable elements. Each chapter presents a review by distinguished experts and analyzes repetitive DNA diversity and abundance, as well as the impact on genome structure, function and evolution. This publication is targeted at scientists and scholars at every level, from students to faculty members, and, indeed, anyone involved or interested in genetics, molecular evolution, molecular biology as well as genomics will find it a valuable source of up-to-date information.

Repetitive DNA is ubiquitous in eukaryotic genomes, and, in many species, comprises the bulk of the genome. Repeats include transposable elements that can self-mobilize and disperse around the genome, and tandemly-repeated satellite DNAs that increase in copy number due to replication slippage and unequal crossing over. Despite their abundance, repetitive DNA is often ignored in genomic studies due to technical challenges in their identification, assembly, and quantification. New technologies and methods are now providing the unprecedented power to analyze repetitive DNAs across diverse taxa. Repetitive DNA is of particular interest because it can represent distinct modes of genome evolution. Some repetitive DNA forms essential genome structures, such as telomeres and centromeres, which are required for proper chromosome maintenance and segregation, whereas others form piRNA clusters that regulate transposable elements; thus, these elements are expected to evolve under purifying selection. In contrast, other repeats evolve selfishly and produce genetic conflicts with their host species that drive adaptive evolution of host defense systems. However, the majority of repeats likely accumulate in eukaryotes in the absence of selection due to mechanisms of transposition and unequal crossing over. Even these neutral repeats may indirectly influence genome evolution as they reach high abundance. In this Special Issue, the contributing authors explore these questions from a range of perspectives.
