Book Description
The possession of plasmids was for a long time recognized only in the bacteria. It is now evident that plasmids, or replicative forms of DNA structurally and experimentally comparable to bacterial plasmids, exist in eukaryotic organisms as well. Such plasmids are in fact common among fungi and higher plants. The present review is undertaken to provide a comprehensive account of the data available on plasmids found in eukaryotic organisms. This review will not consider plasmids of prokaryotic origin, even though certain bacterial plasmids, such as the tumor-inducing (Ti) plasmids of Agrobacterium tumefaciens, may be intimately associated with transformation of the eukaryotic host. This book, moreover, does not consider transformation experiments in eukaryotic hosts involving viral DNA as vectors, although indeed such vectors have been developed for use in plant and animal systems. After a general introduction, providing historical perspective on the nature and role of plasmids, a list of eukaryotic plasmids will be presented according to their origin. This is followed by a detailed discussion of known structure and function. In subsequent chapters the practical implications of eukaryotic plasmids for molecular cloning and biotechnology will be discussed. This latter part traces the development of interest'in biotechnical genetics and gives special consideration to the use of eukaryotic systems for gene cloning. The terminology biotechni cal genetics is introduced to the reader and is used in a general sense as equivalent to genetic engineering. Biotechnical genetics includes, but is not limited to, gene cloning through recombinant DNA technology.

Book Description
This book opens with an essay on the historical perspective of the study of plasmids, reviewing important events and discoveries that have propelled the field forward. The remaining chapters are divided into six sections, detailing basic biological processes such as replication and inheritance functions, specific plasmid systems, plasmid evolution, and use of plasmids as genetic tools. Chapters include use of genomic approaches for the study of plasmid biology, and a review of plasmids from bacteria, archaea, and eukaryotes is presented. In-depth treatment is given to diversity of plasmid systems in the natural environment, and the development of plasmid use in the laboratory is also covered.

Book Description
A book that constitutes the first attempt to comprehensively assemble current knowledge of different types of such elements, highlight recent developments in the field, and challenge the distinction between viruses and linear plasmids. Linear plasmids of microbes represent a heterogenous group of extrachromosomal genetic elements initially assumed to be rare and peculiar. However, we now know that they are fairly frequently occurring plasmids in bacterial and eukaryotic species. Viral strategies to avoid shortening of the linear molecules during replication imply a common ancestry.

Book Description
This book includes the proceedings of a NATO Advanced Study Institute held at Washington State University, Pullman, Washington from July 26 until August 6, 1982. Although genetic engineering in eukaryotes is best developed in yeast and mammalian cells, the reader will find that some emphasis has been put on plant systems. Indeed, it was our position that the development of plant cell genetic transformation would benefit from the interactions between a comparatively smaller number of fungal and animal cell experts and a larger number of plant cell specialists representing various aspects of plant molecular genetic research. On the other hand, it is clear that the ultimate achievements of plant genetic engineering will have a tremendous ~pact on, among other things, food production without generating the problems of ethics encountered when one contempla-tes the genetic modification of human beings. Therefore, this slight bias in favor of the plant kingdom simply reflects our belief that a "second green revolution" will benefit mankind to a greater extent than any other kind of genetic engine ering. The keynote lecture of the Institute was delivered by Dr. John Slaughter, Director of the National Science Foundation, whom we deeply thank for his words of encouragement and commitment to the genetic manipulation of plants.

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
Prokaryotes are profoundly original, highly efficient microorganisms that have played a decisive role in the evolution of life on Earth. Although disjunct, taken together their cells form one global superorganism or biological system. One of the results of their non-Darwinian evolution has been the development of enormous diversity and bio-energetic variety. Prokaryotic cells possess standardized mechanisms for easy gene exchanges (lateral gene transfer) and they can behave like receiving and broadcasting stations for genetic material. Ultimately, the result is a global communication system based on the prokaryotic hereditary patrimony, by analogy, a two-billion-year-old world wide web for their benefit. Eukaryotes have evolved from the association of at least three complementary prokaryotic cells, and their subsequent development has been enriched and accelerated by symbioses with other prokaryotes. One of these symbioses was responsible for the origin of vascular plants which transformed vast sections of the continental surface of the Earth from deserts to areas with luxuriant, life-supporting vegetation. All forms of life on our planet are directly or indirectly sustained and enriched by the positive contribution of prokaryotes. Sorin Sonea and L�o G. Mathieu have been professors at the Department of Microbiology and Immunology (Faculty of Medicine) at the Universit� de Montr�al. They have long been advocates of the ideas presented in this book.

Book Description
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.
