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 Bacterial Plasmids written by Geoffrey Guy Meynell and published by MIT Press (MA). This book was released on 1973 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a sound, scholarly, yet very readable book that organizes the pertinent material on a relatively popular topic in bacterial genetics. In a complicated area where articles are scattered throughout the literature, it should prove an excellent reference source for researchers in microbial genetics and general microbiology, as well as in certain aspects of clinical medicine and in nutrition. Drug-resistance factors are accessory chromosomes, independent of the bacterial chromosome proper, which are of increasing practical concern as they cause a large portion of the antibiotic resistance that is prevalent in medicine and in veterinary practice. Yet these factors are only part of a much larger class of accessory chromosomes known as &"plasmids&" which have played a prominent role in the development of bacterial genetics of molecular biology as a whole. Two other well-known classes are the sex factors, which enable bacteria to transfer their genes to recipients by conjugation, and the bacterial phages&-viruses that grow in bacteria. Despite the great differences in their overt properties, all plasmids exhibit strong fundamental similarities, and it is these general properties rather than their individual peculiarities which are emphasized here. The book first notes how plasmids were discovered. It then discusses the physical structure of their chromosomes, their manner of replication, how they act to bring about conjugation, and other processes they determine. Although the treatment is primarily biological, the book supplies references to laboratory techniques and to the implications of the subject for human and for animal medicine.
Download or read book Bacterial Conjugation written by D.B. Clewell and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Brenner s Encyclopedia of Genetics written by Stanley Maloy and published by Academic Press. This book was released on 2013-03-03 with total page 4360 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
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.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive collection of perspectives by experts in mycobacterial molecular biology Mycobacterium tuberculosis causes one in four avoidable deaths in the developing world and kills more adults than malaria, AIDS, and all tropical diseases combined. Tuberculosis was named a global health emergency by the World Health Organization, a distinction no other disease has received. Although the study of mycobacterial genetics has expanded dramatically, with new investigations into mycobacterial growth, replication, metabolism, physiology, drug susceptibility, and virulence, most of the problems in tuberculosis control that existed in 2000 remain today. Advances in our understanding of mycobacterial genetics have been reflected in exciting recent developments. New diagnostic approaches can identify drug resistance within a few hours, promising new drugs are progressing through the pipeline and into the clinic, and a range of newly developed vaccines are being evaluated. It is an exciting time as the fruits of 30 years of intensive genetic investigation are finally beginning to emerge. Written by leading experts in the field, Molecular Genetics of Mycobacteria, Second Edition, Discusses key areas of current research in mycobacterial genetics Explains the genetics of the physiology, metabolism, and drug sensitivities of M. tuberculosis Presents genetic approaches for manipulating M. tuberculosis This book is an invaluable resource for anyone interested in the molecular genetics and molecular biology of mycobacteria.

Book excerpt: This selected collection of contributions focuses on the modification of organisms through genetic manipulation. Scientists from various disciplines assess the quality of our knowledge on which risk assessment of gene technology methods is currently based. Molecular biology and ecology, but also aspects of evolutionary and population genetics, human genetics and genetically modified food are among the topics covered. The book analyzes the impetus behind, and progress in, research methods which have been introduced into gene-technology risk assessment procedures over the last three years, and, in so doing, reveals gaps in our understanding of evolutionary processes. The history of risk assessment and ethical implications with respect to the deliberate release of GMOs are considered. Finally, the transfer of knowledge from the laboratory to the public, and the role of the media in this process are discussed. This monograph will be of great interest to all those concerned with the risk assessment of genetechnology methods.
