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

Plant viruses are of considerable interest to the science of biology, and their study has contributed significantly to the elucidation of several mysteries of traditional and molecular biology.

The media coverage of natural disasters (hurricanes, fires, floods, ice storms, etc.) indicates the prevalence of natural disasters in most, if not all, ecosystems. In order for scientists to study, understand, and ultimately predict how these disturbances affect ecosystems, it is necessary for them to know more about the physical processes involved in these disturbances and to learn how to couple these processes to the ecological systems. Essential for all ecologists, forest researchers, ...
