The continuous growth of knowledege makes it very difficult for scientists to retrieve comprehensive and accurate data on viruses. The desired information is often dispersed in a variety of books, journals and online resources. This encyclopedia presents the latest facts about all known viruses in a standardized form created by hundreds of the world's leading virologists. Virus taxonomy represents the basic framework that allows an understanding of the complex evolutionary process that continuously takes place among viruses and their hosts. Each of the 300 taxonomically ordered chapters includes detailed information on individual genus members, historical events, the hosts they can affect (animal, man or plant), virion morphology, genome properties, replication strategy, properties of individual transcripts and proteins, sequence accession numbers, biological properties, diseases, recombinant vector constructs, vaccine strains, key references, as well as a high-resolution particle image and a drawing of the genome organization. Its high content of easily accessible detailed information makes this Encyclopedia an indispensable tool for both researchers and lecturers. The new edition includes the recent discoveries made in this field as well as new viruses which have been discovered.
Seeds provide an efficient means in disseminating plant virus and viroid diseases. The success of modern agriculture depends on pathogen free seed with high yielding character and in turn disease management. There is a serious scientific concern about the transmission of plant viruses sexually through seed and asexually through plant propagules. The present book provides the latest information along with the total list of seed transmitted virus and viroid diseases at global level including, the yield losses, diagnostic techniques, mechanism of seed transmission, epidemiology and virus disease management aspects. Additional information is also provided on the transmission of plant virus and virus-like diseases through vegetative propagules. It is also well known that seed transmitted viruses are introduced into new countries and continents during large-scale traffic movements through infected germplasm and plant propogules. The latest diagnostic molecular techniques in different virus-host combinations along with disease management measures have been included. The book shall be a good reference source and also a text book to the research scientists, teachers, students of plant pathology, agriculture, horticulture, life sciences, green house managers, professional entrepreneurs, persons involved in quarantines and seed companies. This book has several important features of seed transmitted virus diseases and is a good informative source and thus deserves a place in almost all university libraries, seed companies and research organizations.
This volume of the series The Plant Viruses is devoted to viruses with rod-shaped particles belonging to the following four groups: the toba moviruses (named after tobacco mosaic virus), the tobraviruses (after to bacco rattle), the hordeiviruses (after the latin hordeum in honor of the type member barley stripe mosaic virus), and the not yet officially rec ognized furoviruses (fungus-transmitted rod-shaped viruses, Shirako and Brakke, 1984). At present these clusters of plant viruses are called groups instead of genera or families as is customary in other areas of virology. This pe culiarity of plant viral taxonomy (Matthews, 1982) is due to the fact that the current Plant Virus Subcommittee of the International Committee of Taxonomy of Viruses is deeply split on what to call the categories or ranks used in virus classification. Some plant virologists believe that the species concept cannot be applied to viruses because this concept, according to them, necessarily involves sexual reproduction and genetic isolation (Milne, 1984; Murant, 1985). This belief no doubt stems from the fact that these authors restrict the use of the term species to biological species. According to them, a collection of similar viral isolates and strains does constitute an individ ual virus, i. e. , it is a taxonomy entity separate from other individual viruses.
Viral Diseases of Field and Horticultural Crops details the fundamental and applied aspects of the viral diseases of field and horticultural crops. The book opens with a historical introduction to plant virology, important plant virologists, and landmarks. It continues with systematic coverage of viral diseases, their economic significance, disease symptoms, host range, mode of transmission, diagnostic techniques, geographic distribution, epidemiology, yield losses, and control and management of the disease. Contributions from an international group of virologists with a wide range of academic, research, professional, and specialized backgrounds in plant virology makes Viral Diseases of Field and Horticultural Crops a comprehensive and must-have resource for those engaged in the study and research of plant virology, microbiology, and plant pathology particularly viral diseases and their impact on field and horticultural crops. - Provides virus characterization according to the disease pattern and symptoms they cause - Covers viral diseases of cereals, oil seeds, legumes, commercial crops, spices and condiments, medicinal and aromatic crops, forage crops, vegetable crops, fruit crops, tree nuts, among others - Discusses advances like applications in nanotechnology, molecular techniques for the detection and characterization of plant viruses, and the development of technologies for detecting plant viruses
Emerging and Reemerging Viral Pathogens: Applied Virology Approaches Related to Human, Animal and Environmental Pathogens, Volume Two presents new research information on viruses and their impact on the scientific community. It provides a reference book on certain viruses in humans, animals and vegetal, along with a comprehensive discussion on interspecies interactions. The book then looks at the drug, vaccine and bioinformatical strategies that can be used against these viruses, giving the reader a clear understanding of transmission. The book's end goal is to create awareness that the appearance of newly transmissible pathogens is a global risk that requires shared/adoptable policies for prevention and control. - Covers most emerging viral disease in humans, animals and plants - Provides the most advanced tools and techniques in molecular virology and the modeling of viruses - Creates awareness that the appearance of new transmissible pathogens is a global risk - Highlights the need to adopt shared policies for the prevention and control of infectious diseases
The Encyclopedia of Plant Viruses and Viroids provides an up-to-date information on the viruses and viroids infecting all types of cultivated and weed plants at global level; and is unique among plant virology texts as it is organized alphabetically by the genus name of the host plant infected. It allows the reader to readily determine all of the different viruses currently reported naturally infecting the plant genus and species. Information is provided for each virus and viroids on common synonyms, current taxonomic status, geographical distribution, symptoms induced, other known hosts, means of transmission and properties of both the virus particles and the genome. Where ever the same virus is known to infect multiple hosts, host-specific information, biological properties and genome characters are presented under each host affected. The index can be utilized to identify other crops infected by the same virus, showing which other crops might be at risk of infection in the event of introduction of a virus that has not previously reported in an area, or which might serve as potential virus reservoirs for infection of more sensitive or economically important crops than the host in which it is initially identified. The taxonomy and nomenclature of the viruses and viroids are followed based on the current guidelines of the 10th ICTV Report, covering up to 2018 and also about many new viruses and viroids that have been reported but not yet recognized as species by ICTV, have been included in this Encyclopedia. The uniqueness of this Encyclopedia is that all the known viruses and viroids affecting more than 1010 plant species at global level are described and the plant species are arranged in alphabetical order of the scientific name of the plant along the relevant information on 1518 viruses and viroids and is the ready-reckoner of the global plant species and their viruses and viroids for students, scientists, teachers of Plant Pathology& Virology; and also for the crop protection professionals, agricultural policymakers, seed companies and quarantine agencies.

The domestication of grapes dates back five thousand years ago and has spread to nearly all continents. In recent years, grape acreage has increased dramatically in new regions, including the United States of America, Chile, Asia (China and India), and Turkey. A major limiting factor to the sustained production of premium grapes and wines is infections by viruses. The advent of powerful molecular and metagenomics technologies, such as molecular cloning and next generation sequencing, allowed the discovery of new viruses from grapes. To date, grapevine is susceptible to 64 viruses that belong to highly diverse taxonomic groups. The most damaging diseases include: (1) infectious degeneration; (2) leafroll disease complex; and (3) rugose wood complex. Recently, two new disease syndromes have been recognized: Syrah decline and red blotch. Losses due to fanleaf degeneration are estimated at $1 billion annually in France alone. Other diseases including leafroll, rugose wood, Syrah de cline and red blotch can result in total crop loss several years post-infection. This situation is further exacerbated by mixed infections with multiple viruses and other biotic as well as adverse abiotic environmental conditions, such as drought and winter damage, causing even greater destruction. The book builds upon the last handbook (written over twenty years ago) on the part of diagnostics and extensively expands its scope by inclusion of molecular biology aspects of select viruses that are widespread and economically most important. This includes most current information on the biology, transmission, genome replication, transcription, subcellular localization, as well as virus-host interactions. It also touches on several novel areas of scientific inquiry. It also contains suggested directions for future research in the field of grapevine virology.
