This book assembles a comprehensive collection of plant virus electron micrographs of good quality, offers a consistent treatment, and backs the visual data with a consistent and comprehensive text. Although this book is primarily about the structure of virus particles and infected cells, the results of biochemical experiments are referred too when relevant, so that the virus particles described appear as part of a replicating complex. Similarly, infected cells are portrayed as active rather than static structures.

This book deals with the structure and replication of plant viruses, viroids, satellites of plant viruses, and spiroplasmas and neatly sums up the state of our knowledge about these aspects of these pathogens.Published information about single-stranded positive-sense RNA plant viruses is far greater than for any other group of plant pathogens.The book caters to the needs of students as well as researchers and is illustrated with micrographs, figures of postulated models, and genetic maps

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.

Authored by electron microscopists and leading members of the International Committee on Taxonomy of Viruses (ICTV), the Atlas of Virus Diagrams includes chapters on virus classification. The diagrams, selected for content and historic and aesthetic value, illustrate vertebrate, invertebrate, and plant bacterial viruses taken from English, French, and German language virological literature. The book presents this information in three sections: Overviews, including vertebrate and plant viruses Viruses with cubic and helical symmetry Viruses with binary symmetry (tailed bacteriophages).
