This book was released on 2023-12-27 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genome of a living being is composed of DNA sequences with diverse origins. Beyond single-copy genes, whose product has a biological function that can be inferred by experimentation, certain DNA sequences, present in a large number of copies, escape the most refined approaches aimed at elucidating their precise role. The existence of what 20th century geneticists had already perceived (and wrongly described as "junk DNA"!) was confirmed by the sequencing of the first complex genomes, including that of Homo sapiens. A large part of what defines a living thing is not unique, but repeated, sometimes a very large number of times, increasing in complexity with successive duplications and multiplication. Understanding and defining the many functions of this myriad of repeated sequences, as well as their evolution through natural selection, has become one of the major challenges for 21st century genomics.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Science, like the biological sciences in general, has undergone seismic shifts in the last thirty or so years. Of course science is always changing and metamorphosing, but these shifts have meant that modern plant science has moved away from its previous more agricultural and botanical context, to become a core biological discipline in its own right. However the sheer amount of information that is accumulating about plant science, and the difficulty of grasping it all, understanding it and evaluating it intelligently, has never been harder for the new generation of plant scientists or, for that matter, established scientists. And that is precisely why this Handbook of Plant Science has been put together. Discover modern, molecular plant sciences as they link traditional disciplines! Derived from the acclaimed Encyclopedia of Life Sciences! Thorough reference of up-to-the minute, reliable, self-contained, peer-reviewed articles – cross-referenced throughout! Contains 255 articles and 48 full-colour pages, written by top scientists in each field! The Handbook of Plant Science is an authoritative source of up-to-date, practical information for all teachers, students and researchers working in the field of plant science, botany, plant biotechnology, agriculture and horticulture.

Book excerpt: This volume contains the presentations of the principal speakers at the NATO Advanced Study Institute held at Porto Portese, Italy,23 August - 2 September, 1982. This meeting was the third in a series devoted to the molecular biology of plants. The initial meeting was held in Strasbourg, France in 1976 (J. Weil and L. Bogorad, organizers), and the second in Edinburgh, Scotland in 1979 (C. Leaver, organizer). As in these previous meetings, we have attempted to cover the major topics of plant molecular biology so as to promote the integration of information emerging at an accelerating rate from the various sub-disciplines of the field. In addition, we have introduced several topics, unique to higher plants, that have not yet been approached with the tools of molec ular biology, but that should present new and important aspects of plants amenable to study in terms of DNA -+ RNA -+ Protein. This meeting also served to inaugerate the new International Society for Plant Molecular Biology. The need for this society is, like the NATO meetings themselves, an indication of the growth, vitalitv and momentum of this field of research.

Available in PDF, EPUB and Kindle. Book excerpt: The genomes of humans, as well as many other species, are interspersed with hundreds of thousands of tandem repeats of DNA sequences. Those tandem repeats located as codons within open reading frames encode amino acid runs, such as polyglutamine and polyalanine. Tandem repeats have not only been implicated in biological evolution, development and function but also in a large collection of human disorders. In Tandem Repeats in Genes, Proteins, and Disease: Methods and Protocols, expert researchers in the field detail many methods covering the analysis of tandem repeats in DNA, RNA and protein, in healthy and diseased states. This will include molecular genetics, molecular biology, biochemistry, proteomics, biophysics, cell biology, and molecular and cellular approaches to animal models of tandem repeat disorders. Written in the highly successful Methods in Molecular BiologyTM 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 avoiding known pitfalls. Authoratative and Practical, Tandem Repeats in Genes, Proteins, and Disease: Methods and Protocols aids scientists in continuing to study the unique methodological challenges that come from repetitive DNA and poly-amino acid sequences.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
