Book Description
This is an essential bench book that describes the molecular biology, structure, detection, purification, and pathogenesis of viroids and satellites. The volume begins with an overview of the current status of the field, followed by four chapters describing details of methodology, nucleic acid probes, purification, sequence variation, complementary RNA probes, polyacrylamide gel electrophoresis and mutational analysis of viroid movement and pathogenicity. Remaining chapters discuss such topics as viroids that cause apple scar disease in China, the cadang-cadang disease of palms in the Pacific area, viroid-like satellite RNAs, and a comparison of plant viroids with the human-pathogenic delta agent. The book will be a major reference work on viroids for years to come and an essential resource for virologists, molecular biologists, microbiologists, geneticists, biochemists, biomedical investigators, plant pathologists, and agricultural researchers.

Book Description
The practical need to partition the world of viruses into distinguishable, universally agreed upon entities is the ultimate justification for developing a virus classification system. Since 1971, the International Committee on Taxonomy of Viruses (ICTV) operating on behalf of the world community of virologists has taken on the task of developing a single, universal taxonomic scheme for all viruses infecting animals (vertebrate, invertebrates, and protozoa), plants (higher plants and algae), fungi, bacteria, and archaea. The current report builds on the accumulated taxonomic construction of the eight previous reports dating back to 1971 and records the proceedings of the Committee since publication of the last report in 2005. Representing the work of more than 500 virologists worldwide, this report is the authoritative reference for virus organization, distinction, and structure.

Book Description
The seminal text Plant Virology is now in its fifth edition. It has been 10 years since the publication of the fourth edition, during which there has been an explosion of conceptual and factual advances. The fifth edition of Plant Virology updates and revises many details of the previous edition while retaining the important earlier results that constitute the field's conceptual foundation. Revamped art, along with fully updated references and increased focus on molecular biology, transgenic resistance, aphid transmission, and new, cutting-edge topics, bring the volume up to date and maintain its value as an essential reference for researchers and students in the field. Thumbnail sketches of each genera and family groups Genome maps of all genera for which they are known Genetic engineered resistance strategies for virus disease control Latest understanding of virus interactions with plants, including gene silencing Interactions between viruses and insect, fungal, and nematode vectors Contains over 300 full-color illustrations

Book Description
More than seven years have passed since the first monograph on viroids was published. At that time, the existence of viroids as a novel type of pathogen far smaller than viruses had been amply demonstrated and some of their unusual molecular properties had been elucidated, but the entry of molecular biology into viroid research was still in its infancy. Since that time, our knowledge of the molecular properties of viroids has increased exponentially and viroids have become even more fasci nating than was the case seven years ago. Today, aside from transfer RNA, viroids are probably the best known type of RNA-at least from a struc tural standpoint. Much less is known of the mechanisms of viroid func tion, such as the exact pathway and enzymology of viroid replication and the biochemistry of viroid pathogenesis. Recently, however, emphasis in viroid research has shifted from structural to functional themes and im portant beginnings have been made in the elucidation of viroid struc ture-function relationships. With the discovery of viroidlike RNAs within the capsids of certain plant viruses and the finding of surprising structural similarities between viroids and plant satellite RNAs, the conceptual gap between viroids and conventional viruses has significantly narrowed. Even beyond virology, connecting links with cellular RNAs have come to light and the long isolation of viroids land "viroidologists"J has come to an end.

Book Description
“Weird indeed, and not a little wonderful.”—Nature In the 1980s and 1990s, in places where no one thought it possible, scientists found organisms they called extremophiles: lovers of extremes. There were bacteria in volcanic hydrothermal vents on the ocean floor, single-celled algae in Antarctic ice floes, and fungi in the cooling pools of nuclear reactors. But might there be life stranger than the most extreme extremophile? Might there be, somewhere, another kind of life entirely? In fact, scientists have hypothesized life that uses ammonia instead of water, life based not in carbon but in silicon, life driven by nuclear chemistry, and life whose very atoms are unlike those in life we know. In recent years some scientists have begun to look for the tamer versions of such life on rock surfaces in the American Southwest, in a “shadow biosphere” that might impinge on the known biosphere, and even deep within human tissue. They have also hypothesized more radical versions that might survive in Martian permafrost, in the cold ethylene lakes on Saturn’s moon Titan, and in the hydrogen-rich atmospheres of giant planets in other solar systems. And they have imagined it in places off those worlds: the exotic ices in comets, the vast spaces between the stars, and—strangest of all—parallel universes. Distilling complex science in clear and lively prose, David Toomey illuminates the research of the biological avant-garde and describes the workings of weird organisms in riveting detail. His chapters feature an unforgettable cast of brilliant scientists and cover everything from problems with our definitions of life to the possibility of intelligent weird life. With wit and understanding that will delight scientists and lay readers alike, Toomey reveals how our current knowledge of life forms may account for only a tiny fraction of what’s really out there.

Book Description
Completely revised and updated, the new edition of this groundbreaking text integrates basic virology with pathophysiological conditions to examine the connection between virology and human disease. Most virology textbooks focus on the molecular biology involved without adequate reference to physiology. This text focuses on viruses that infect humans, domestic animals and vertebrates and is based on extensive course notes from James Strauss’ virology class at the California Institute of Technology taught for over 30 years. Expertly depicting in color the molecular structure and replication of each virus, it provides an excellent overview for students and professionals interested in viruses as agents of human disease. Includes over 30% new material - virtually all of the figures and tables have been redrawn to include the latest information and the text has been extensively rewritten to include the most up-to-date information Includes a new chapter on emerging and reemerging viral diseases such as avian flu, SARS, the spread of West Nile virus across America, and the continuing spread of Nipah virus in Southeast Asia Further reading sections at the end of each chapter make it easy find key references World maps depicting the current distribution of existing and newly emerging viruses are also incorporated into the text
