Book Description
Bacterial plasmids originating in a wide range of genera are being studied from a variety of perspectives in hundreds of laboratories around the globe. These elements are well known for carrying "special" genes that confer important survival properties, frequently neces sary under atypical conditions. Classic examples of plasmid-borne genes are those provid ing bacterial resistance to toxic substances such as antibiotics, metal ions, and bacte riophage. Often included are those determining bacteriocins, which may give the bacterium an advantage in a highly competitive environment. Genes offering metabolic alternatives to the cell under nutritionally stressed conditions are also commonly found on plasmids, as are determinants important to colonization and pathogenesis. It is likely that in many, if not most, cases plasmids and their passenger determinants represent DNA acquired recently by their bacterial hosts, and it is the characteristic mobility of these elements that enables their efficient establishment in new bacterial cells by the process known as conjugation. Whereas many plasmids are fully capable of promoting their own conjugal transfer, others move only with help from coresident elements. The ability of a plasmid to establish itself in a variety of different species is com mon, and recent studies have shown that transfer can in some cases occur from bacterial cells to eukaryotes such as yeast.

Book Description
This timely volume reviews the molecular mechanisms and regulation aspects of conjugation in a variety of bacterial systems. An international group of contributors examine the movement of plasmids and conjugative transposons across species and kingdom barriers, and discuss the significance of the transfer phenomenon from clinical, environmental, and industrial perspectives.

Book Description
"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.

Book Description
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.

Book Description
Bacterial genetics has become one of the cornerstones of basic and applied microbiology and has contributed key knowledge for many of the fundamental advances of modern biology. The second edition of this comprehensive yet concise text, first published in 1981, has been thoroughly updated and redesigned to account for new developments in this rapidly expanding field. All of the major topics in modern bacterial and bacteriophage genetics are presented, among them mutations and mutagenesis, genetics of T4 bacteriophage and other intemperate and temperate phages, transduction, transformation, conjugation and plasmids, recombination and repair, probability laws for prokaryote cultures, as well as applied bacterial genetics.

Book Description
In accordance with its predecessor, the completely revised and expanded Second Edition of Modern Microbial Genetics focuses on how bacteria and bacteriophage arrange and rearrange their genetic material through mutation, evolution, and genetic exchange to take optimal advantage of their environment. The text is divided into three sections: DNA Metabolism, Genetic Response, and Genetic Exchange. The first addresses how DNA replicates, repairs itself, and recombines, as well as how it may be manipulated. The second section is devoted to how microorganisms interact with their environment, including chapters on sporulation and stress shock, and the final section contains the latest information on classic exchange mechanisms such as transformation and conjugation. Chapters include: * Gene Expression and Its Regulation * Single-Stranded DNA Phages * Genetic Tools for Dissecting Motility and Development of Myxococcus xanthus * Molecular Mechanism of Quorum Sensing * Transduction in Gram-Negative Bacteria * Genetic Approaches in Bacteria with No Natural Genetic Systems The editors also cultivate an attention to global regulatory systems throughout the book, elucidating how certain genes and operons in bacteria, defined as regulons, network and cooperate to suit the needs of the bacterial cell. With clear appreciation for the impact of molecular genomics, this completely revised and updated edition proves that Modern Microbial Genetics remains the benchmark text in its field.

Book Description
The explosion of the field of genetics over the last decade, with the new technologies that have stimulated research, suggests that a new sort of reference work is needed to keep pace with such a fast-moving and interdisciplinary field. Brenner's Encyclopedia of Genetics, Second Edition, Seven Volume Set, builds on the foundation of the first edition by addressing many of the key subfields of genetics that were just in their infancy when the first edition was published. The currency and accessibility of this foundational content will be unrivalled, making this work useful for scientists and non-scientists alike. Featuring relatively short entries on genetics topics written by experts in that topic, Brenner's Encyclopedia of Genetics, Second Edition, Seven Volume Set provides an effective way to quickly learn about any aspect of genetics, from Abortive Transduction to Zygotes. Adding to its utility, the work provides short entries that briefly define key terms, and a guide to additional reading and relevant websites for further study. Many of the entries include figures to explain difficult concepts. Key terms in related areas such as biochemistry, cell, and molecular biology are also included, and there are entries that describe historical figures in genetics, providing insights into their careers and discoveries. This 7-volume set represents a 25% expansion from the first edition, with over 1600 articles encompassing this burgeoning field Thoroughly up-to-date, with many new topics and subfields covered that were in their infancy or not inexistence at the time of the first edition. Timely coverage of emergent areas such as epigenetics, personalized genomic medicine, pharmacogenetics, and genetic enhancement technologies Interdisciplinary and global in its outlook, as befits the field of genetics Brief articles, written by experts in the field, which not only discuss, define, and explain key elements of the field, but also provide definition of key terms, suggestions for further reading, and biographical sketches of the key people in the history of genetics

Book Description
Forty years ago, three medical researchers--Oswald Avery, Colin MacLeod, and Maclyn McCarty--made the discovery that DNA is the genetic material. With this finding was born the modern era of molecular biology and genetics.
