Book Description
Advances in molecular biology have enabled leaps forward in the determination of virus phylogenetic history. This detailed 1995 book results from the invitation to foremost experts to give essays on aspects of virus biology. Initial chapters cover impacts of viruses and their control. Further chapters detail genetic variation of viruses and the molecular basis of interrelations with hosts. This leads to discussions of interactions with the host at the population level, and their molecular basis and evolution. Seventeen chapters follow, by specialists on particular groups of viruses describing their impact, genetic origins, sources of variation, population genetics and interactions with hosts. Practical virologists will find the chapters on phylogenetic analysis techniques very useful. The adaptive nature of viruses makes this work highly relevant to evolutionists.

Book Description
New viral diseases are emerging continuously. Viruses adapt to new environments at astounding rates. Genetic variability of viruses jeopardizes vaccine efficacy. For many viruses mutants resistant to antiviral agents or host immune responses arise readily, for example, with HIV and influenza. These variations are all of utmost importance for human and animal health as they have prevented us from controlling these epidemic pathogens. This book focuses on the mechanisms that viruses use to evolve, survive and cause disease in their hosts. Covering human, animal, plant and bacterial viruses, it provides both the basic foundations for the evolutionary dynamics of viruses and specific examples of emerging diseases. NEW - methods to establish relationships among viruses and the mechanisms that affect virus evolution UNIQUE - combines theoretical concepts in evolution with detailed analyses of the evolution of important virus groups SPECIFIC - Bacterial, plant, animal and human viruses are compared regarding their interation with their hosts

Book Description
Virus as Composition, Complexity, Quasispecies, Dynamics, and Biological Implications, Second Edition, explains the fundamental concepts surrounding viruses as complex populations during replication in infected hosts. Fundamental phenomena in virus behavior, such as adaptation to changing environments, capacity to produce disease, and the probability to be transmitted or respond to treatment all depend on virus population numbers. Concepts such as quasispecies dynamics, mutations rates, viral fitness, the effect of bottleneck events, population numbers in virus transmission and disease emergence, and new antiviral strategies are included. The book's main concepts are framed by recent observations on general virus diversity derived from metagenomic studies and current views on the origin and role of viruses in the evolution of the biosphere. Features current views on key steps in the origin of life and origins of viruses Includes examples relating ancestral features of viruses with their current adaptive capacity Explains complex phenomena in an organized and coherent fashion that is easy to comprehend and enjoyable to read Considers quasispecies as a framework to understand virus adaptability and disease processes

Book Description
Virology is in a sense both one of the most important precursors and one of the most significant beneficiaries of structural and cellular molecular biology. Numerous breakthroughs in our understanding of the molecular interactions of viruses with host cells are ready for translation into medically important applications such as the prevention and treatment of viral infections. This book collects a wide variety of examples of frontline research into molecular aspects of viral infections from virological, immunological, cell- and molecular-biological, structural, and theoretical perspectives. Contributors are world leaders in their fields of study and represent prestigious academic and research institutions Review articles vary vastly in scope: some focus on a narrowly defined scientific problem of one particular virus with careful introduction for the non-specialist; others are essays in general and comparative virology with forays into specific viral species or molecules The different perspectives complement each other and collectively the contributions provide an impression of the fast-moving frontlines of virology while showing how the problems have evolved Structural data are presented through high-quality illustrations

Book Description
the discovery of the "splicing" of the gene transcripts, the list would include the whole molecular genetics of the lambda bacteriophage, the notions of "promotor," "repressor," and "integration," the discovery of the reverse flow of genetic information, the very existence of oncogenes, the S'-terminal "cap" struc ture of eukaryotic mRNAs, ... Electronmicroscopy, ultracentrifugation and tissue culture were the landmarks on the way of the young science. During the past few years, however, a major (and not so silent) revolution took place: recombinant DNA technology with all its might entered in our laboratories, and restriction mapping of cloned genomes and sequencing gels have replaced plaque counting and sucrose gradients. The new techniques have made it possible to "dissect" the entire genome of a virus at the molecular level, and studies that would have been dreamt of just in the mid-seventies became the everyday experiments of our days. With new insight into the structure of viral genomes, and a deeper understanding of the mechanisms that regulate their expression, our view of viruses was bound to change: this volume bears witness to this impressive advance.

Book Description
This book contemplates the structure, dynamics and physics of virus particles: From the moment they come into existence by self-assembly from viral components produced in the infected cell, through their extracellular stage, until they recognise and infect a new host cell and cease to exist by losing their physical integrity to start a new infectious cycle. (Bio)physical techniques used to study the structure of virus particles and components, and some applications of structure-based studies of viruses are also contemplated. This book is aimed first at M.Sc. students, Ph.D. students and postdoctoral researchers with a university degree in biology, chemistry, physics or related scientific disciplines who share an interest or are actually working on viruses. We have aimed also at providing an updated account of many important concepts, techniques, studies and applications in structural and physical virology for established scientists working on viruses, irrespective of their physical, chemical or biological background and their field of expertise. We have not attempted to provide a collection of for-experts-only reviews focused mainly on the latest research in specific topics; we have not generally assumed that the reader knows all of the jargon and all but the most recent and advanced results in each topic dealt with in this book. In short, we have attempted to write a book basic enough to be useful to M.Sc and Ph.D. students, as well as advanced and current enough to be useful to senior scientists with an interest in Structural and/or Physical Virology.

Book Description
Two decades ago, recombinant DNA technology or genetic engineering ushered in a new era in the study of plant viruses. The major breakthrough came in the eighties, primarily due to the development of new methods for RNA reverse transcription and cDNA cloning, along with restriction enzyme mapping and rapid nucleotide sequencing. An information explosion in various molecular aspects of plant viruses was caused by these studies. Current research efforts investigate the study of viral genomes, genetic maps, genes and gene expression, gene products, and genetic basis of virus functions and biological properties. Molecular Biology of Plant Viruses analyzes, collates and reviews such published information. Additionally, it demonstrates the mechanisms of genetic variability; brings out the molecular basis of virus transport in plants and of virus transmission by vectors and of disease symptomatology; and discusses molecular biology of viroids and transgenic plants. It also treats the recently discovered genetic phenomenon of gene silencing and the gene-for-gene interactions between the hosts and plant viruses. Molecular Biology of Plant Viruses is an excellent reference, providing insight into the exciting research developments made in the field.
