This interesting handbook discusses 145 plant viruses in 27 groups and 31 unclassified viruses in naturally infected legumes. The viruses were observed in field infections of 281 species in 64 genera of the Leguminosae. The book presents information regarding resistance sources and resistance-breeding, vectors, seed transmission, and host ranges. Measurements of virus properties are organized in tabular form for particle dimensions, serological relationships, nucleic acid percentages, sedimentation coefficients of particles and nucleic acids, molecular weights of nucleic acids and coat proteins, optical density, and buoyant density. Handbook of Viruses Infecting Legumes is unique in that it relates inclusion cytology to plant virus detection, identification, and classification. Light and electron micrographs illustrate morphology, location, and staining reactions of inclusions. Of the 27 groups that contain viruses infecting legumes in nature, inclusions are diagnostic at the group level in 15 of these groups. Plant breeders, diagnosticians, plant virologists, and students of plant virology will find this an indispensable guide to legume viruses.

The original aim of this book was to cover different aspects of the tradi tionally "filamentous" potex-, carla-, poty-, clostero-, and capilloviruses. The title The Filamentous Plant Viruses seemed the only suitable one, but it has led us to discuss also the quite different filamentous viruses of the rice stripe group-recently officially named the tenuivirus group which otherwise, indeed, might not have been conveniently covered in any volume of this series. The question must be asked: What is there new that justifies the presentation of a book of this kind? An outline of the answer may be Among the traditional filamentous viruses, much pro given as follows. gress has been made in elucidating the physical structure of potexvirus particles, and this work serves as an excellent model for discussion of and future experiments on the poty-, carla-, clostero-, and capilloviruses, which have comparable structures, although they are more difficult to manipulate. Work on the structure and strategy of the genomes of poty viruses is, however, relatively advanced and at a very interesting stage. The helper component that assists the aphid transmission of potyviruses has also recently received considerable attention, although the more we know about that, the less seems clear about the aphid transmission of the carlaviruses and closteroviruses, which apparently neither possess nor require a helper component.

Viruses: Molecular Biology, Host Interactions, and Applications to Biotechnology provides an up-to-date introduction to human, animal and plant viruses within the context of recent advances in high-throughput sequencing that have demonstrated that viruses are vastly greater and more diverse than previously recognized. It covers discoveries such as the Mimivirus and its virophage which have stimulated new discussions on the definition of viruses, their place in the current view, and their inherent and derived 'interactomics' as defined by the molecules and the processes by which virus gene products interact with themselves and their host's cellular gene products. Further, the book includes perspectives on basic aspects of virology, including the structure of viruses, the organization of their genomes, and basic strategies in replication and expression, emphasizing the diversity and versatility of viruses, how they cause disease and how their hosts react to such disease, and exploring developments in the field of host-microbe interactions in recent years. The book is likely to appeal, and be useful, to a wide audience that includes students, academics and researchers studying the molecular biology and applications of viruses - Provides key insights into recent technological advances, including high-throughput sequencing - Presents viruses not only as formidable foes, but also as entities that can be beneficial to their hosts and humankind that are helping to shape the tree of life - Features exposition on the diversity and versatility of viruses, how they cause disease, and an exploration of virus-host interactions

Viruses are widely present in nature, and numerous viral species with a variety of unique characteristics have been identified so far. Even now, new emerging or re-emerging viruses are being found or re-found as novel viral classes or as quasi-species. Indeed, viruses are everywhere. Of note, viruses are pivotal as targets and tools of basic and applied sciences. On one hand, portions of the viruses are infectious for animals including humans, and cause various diseases in infected hosts by distinct mechanisms and at a different level of severity. While many of viruses are known to co-exist quietly with their hosts, pathogenic viruses certainly affect and threaten our society as well as individuals to provoke serious medical or economic attention. We should act against certain dreadful and highly infectious viruses as a global problem. Animal RNA viruses can readily mutate to adapt themselves in their hostile environments for their survival. Resultant viruses may sometimes show essentially altered phenotypes from the original parental strains. This fundamental and general property of animal RNA viruses represents major extensive issues of scientific, medical, and/or economic importance. In this Research Topic, we have focused on the high mutability of animal RNA viruses, and selected relevant articles on animal viruses of broad-ranges such as primate lentiviruses, influenza viruses, paramyxoviruses, flaviviruses, rabies virus, norovirus, picornaviruses, and picobirnavirus. Each article has taken up intriguing aspects of the subject viruses. We are sure that readers acquire important information on virus mutation, adaptation, diversification, and evolution, and hope that researchers in the field related to virology gain some solid hints from the reported articles for further virological and /or medical studies. Finally, we thank all the contributing researchers in this Research Topic, entitled “Highly Mutable Animal RNA Viruses: Adaptation and Evolution”, for their elegant and interesting works.

This volume contains seven chapters, based on papers presented at a Symposium on Insect Viruses, held in conjunction with the 67th Annual Meeting of the American Society for Microbiology in New York, N. Y. , on 30 April-4 May, 1967. The Symposium was organized to bring together outstanding workers interested in various areas of insect virology, and allow an opportunity for a discussion of problems, approaches, and methods that would lead to further progress in basic and applied research. One of the princi pal reasons for holding the Symposium at this time was the feeling that the divergent areas of research, up to now studied separately by entomologists, medical and public health workers, geneticists, and plant pathologists, would be brought together, crossing the artificial borders and finding new, exciting and inspiring vistas. Insect viruses provide a rare opportunity to get acquainted with the work and methods of investigators in such related and yet distant fields. Following the symposium, a decision was made to publish the papers in a single volume, extending the contents to provide a complete and scholarly review of each subject. Since viruses affecting insects have received little attention until recent years, it was felt that a fully documented presentation of diverse areas of insect virology merited publication. The invited authors, all recognized authorities in their respective fields, prepared their contri butions in such a way that each is a concise unit.

Baculoviruses are perhaps unique among viruses in the breadth of their biotechnological applications: these insect specific viruses are used not only for insect pest management purposes, but also as laboratory research tools for production of recombinant proteins and for protein display, and as potential vectors for human gene therapy. In addition to highlighting recent advances, this volume provides a comprehensive review of the biotechnological applications of these and other insect viruses in both the academic and private sectors.
