Download or read book The Dynamic Bacterial Genome written by Peter Mullany and published by Cambridge University Press. This book was released on 2005-09-26 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book provides an in-depth analysis of the mechanisms and biological consequences of genome rearrangements in bacteria. Each chapter examines the mechanisms involved in genome rearrangements and the direct biological consequences of these events. Because genome rearrangements are so important in evolution, at least one of the chapters views the phenomenon from an evolutionary angle. This book provides the reader with a holistic view of genome rearrangements (i.e., studies on both the biological consequences of genome rearrangement and the mechanisms underlying these processes are presented)." "The book is written by leading research workers in the field and is aimed at final-year undergraduates, postgraduate and postdoctoral workers, and established biologists."--BOOK JACKET.

Download or read book Horizontal Gene Pool written by Christopher M. Thomas and published by CRC Press. This book was released on 2003-09-02 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacteria are the most ubiquitous of all organisms. Responsible for a number of diseases and for many of the chemical cycles on which life depends, they are genetically adaptable. Vital to this adaptability is the existence of autonomous genetic elements-plasmids-which promote genetic exchange and recombination. The genes carried by any particular plasmid may be found in only a few individuals of any species but can also be shared with other species and thus constitute a horizontal gene pool. This book explains the various contributions that plasmids make to this pool: the replication, stable inheritance and transfer modules, the phenotypic markers they carry, the way they evolve, the ways they contribute to their host population and the approaches that we use to study and classify them. It also looks at what we know about their activity in natural communities and the way that they interact with other mobile elements to promote bacterial evolution.

Download or read book DNA Traffic in the Environment written by Hiromi Nishida and published by Springer. This book was released on 2019-02-21 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively discusses our current understanding of the role and biological mechanisms of horizontal transfer of genetic elements in the environment, which has been important in the evolution of prokaryotes (archaea and bacteria). Horizontal transfer of genetic elements generates variations of prokaryotes and their genomes. Comparative studies of genomes revealed that it frequently occurred during archaeal and bacterial evolution. The book introduces a variety of studies related to horizontal gene transfer, gene silencing, plasmids, phages, transposons, and the emergence of microbes that degrade man-made xenobiotics and have antimicrobial resistance. Written by leading researchers in DNA traffic, the book is a valuable guide to horizontal transfer for both young scientists and experts in the field.
Download or read book Microbial Megaplasmids written by Edward Schwartz and published by Springer Science & Business Media. This book was released on 2009-01-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Megaplasmids are extrachromosomal genetic elements in the size range of 100 kb and larger. They are found in physiologically and phylogenetically diverse groups of bacteria and archaea. By definition, megaplasmids are not essential for the viability of their hosts under all growth conditions, but paradoxically many megaplasmids carry the genetic information for the defining and characteristic traits of the organism in which they reside. Microbial Megaplasmids reviews our knowledge of the extensively studied representatives, such as the catabolic plasmids of the pseudomonads, the rhizobial Sym plasmids, the Ti plasmids of the genus Agrobacterium and the giant enterobacterial virulence plasmids. It also presents snapshots of more recently discovered megaplasmids. The contribution of megaplasmids to the biology of their hosts is described, highlighting the interactions between megaplasmid and chromosomal genes.

Download or read book Plant Transposons and Genome Dynamics in Evolution written by Nina V. Fedoroff and published by John Wiley & Sons. This book was released on 2013-01-16 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Antibiotic Resistance written by Derek J. Chadwick and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antibiotic Resistance: Origins, Evolution, Selection and Spread Chairman: Stuart B. Levy, 1997 Over the last 50 years, the rapid increase in the use of antibiotics, not only in people, but also in animal husbandry and agriculture, has delivered a selection unprecedented in the history of evolution. Consequently, society is facing one of its gravest public health problems-the emergence of infectious bacteria with resistance to many, and in some cases all, available antibiotics. This book brings together a multidisciplinary group of experts to discuss this problem. It begins by examining the origins of resistance and goes on to look at how the use of antibiotics in human medicine and farming/agriculture has selected for resistant bacteria. Separate chapters describe the evolution of resistance determinants and how these are spread both within and between bacterial species. Finally, the book contains discussions on strategies for countering the threat of antibiotic resistance. A major re-thinking of our approach to the treatment of infectious diseases is proposed-that antibiotic resistance should be seen as a problem created by the disruption of normal microbial ecology. To restore efficacy to earlier antibiotics, and to maintain the success of new antibiotics that are introduced, we need to use these drugs in a way that ensures an ecological balance that favours the predominance of susceptible bacteria.
Download or read book Microbial Biochemistry written by G. N. Cohen and published by Springer. This book was released on 2014-07-21 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial physiology, biochemistry and genetics allowed the formulation of concepts that turned out to be important in the study of higher organisms. In the first section, the principles of bacterial growth are given, as well as the description of the different layers that enclose the bacterial cytoplasm, and their role in obtaining nutrients from the outside media through different permeability mechanism described in detail. A chapter is devoted to allostery and is indispensable for the comprehension of many regulatory mechanisms described throughout the book. Another section analyses the mechanisms by which cells obtain the energy necessary for their growth, glycolysis, the pentose phosphate pathway, the tricarboxylic and the anaplerotic cycles. Two chapters are devoted to classes of microorganisms rarely dealt with in textbooks, namely the Archaea, mainly the methanogenic bacteria, and the methylotrophs. Eight chapters describe the principles of the regulations at the transcriptional level, with the necessary knowledge of the machineries of transcription and translation. The next fifteen chapters deal with the biosynthesis of the cell building blocks, amino acids, purine and pyrimidine nucleotides and deoxynucleotides, water-soluble vitamins and coenzymes, isoprene and tetrapyrrole derivatives and vitamin B12. The two last chapters are devoted to the study of protein-DNA interactions and to the evolution of biosynthetic pathways. The considerable advances made in the last thirty years in the field by the introduction of gene cloning and sequencing and by the exponential development of physical methods such as X-ray crystallography or nuclear magnetic resonance have helped presenting metabolism under a multidisciplinary attractive angle.
