It has been ten years since the publication of the third edition of this seminal text on plant virology, during which there has been an explosion of conceptual and factual advances. The fourth edition updates and revises many details of the previous edition, while retaining the important older results that constitute the field's conceptual foundation.Key features of the fourth edition include:* 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

This compilation of articles elaborates on plant virus diseases that are among the most recent epidemiological concerns. The chapters explore several paradigms in plant virus epidemiology, outbreaks, epidemics, and pandemics paralleling zoonotic viruses and that can be consequential to global food security. There is evidence that the local, regional, national, and global trade of agricultural products has aided the global dispersal of plant virus diseases. Expanding farmlands into pristine natural areas has created opportunities for viruses in native landscapes to invade crops, while the movement of food and food products disseminates viruses, creating epidemics or pandemics. Moreover, plant virus outbreaks not only directly impact food supply, but also incidentally affect human health.

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.

Plants possess a rather complex and efficient immune system. During their evolutionary history, plants have developed various defense strategies in order to recognize and distinguishing between self and non-self, and face pathogens and animal pests. Accordingly, to study the plant innate immunity represents a new frontier in the plant pathology and crop protection fields. This book is structured in 6 sections. The first part introduces some basic and general aspects of the plant innate immunity and crop protection. Sections 2–5 focus on fungal and oomycete diseases (section 2), bacterial and phytoplasma diseases (section 3), virus diseases (section 4), and insect pests (section 5), with a number of case studies and plant–pathogen/pest interactions. The last section deals with plant disease detection and control. The book aims to highlight new trends in these relevant areas of plant sciences, providing a global perspective that is useful for future and innovative ideas.

Many of the world's most important food crops are grown in the tropics and the majority of them are affected with one or another virus or viroid diseases.  Plant virus and sub-viral agents are one of the factors that affect productivity and cause vast economic losses to staple crops across the tropics.  Sustained efforts are being made in universities and research institutions of both state and central facilities, and have resulted in dramatic success in managing some of the most devastating virus diseases.  However, emergence of new viruses and strains of existing viruses, along with changing contexts due to agricultural intensification and climate change resulted in creating new challenges and demanding even greater effort to overcome hurdles to increase agricultural productivity, food availability and economic development. Methods for the detection and identification of viruses and virus-like diseases in plants and vectors play a critical role in plant virus epidemiology and in turn plant virus management.  Advancements in serological and molecular techniques have greatly improved the speed and accuracy of virus and sub-viral pathogen identification.  To keep up with the constant threat of emerging and re-emerging plant viruses, it is necessary to identify, predict and monitor sources of outbreaks at the worldwide level to minimize small infection proportions from becoming devastating pandemics.  Diagnosis of plant virus and sub-viral agents and their  prevention / management is an integral part of agricultural production systems and regulatory frame works that exist in almost all tropical countries.  Plant virus epidemiology provides powerful tools to investigate key factors that contribute to virus epidemics in agricultural crops.  These epidemiological approaches help to guide decisions regarding plant protection strategies.  The dynamics of a particular virus disease epidemic depends on the number of vectors and their activity, sources of virus and vectors, climatic conditions and a complex series of virus - plant - vector interactions.  The importance of epidemiology needs to be realized for the management of virus diseases in an integrated disease management program (IPM) and also for generating information on pest / disease-free areas and for pest risk analysis, which is an obligation for our international trade.  Even though there are number of virus and virus-like disease management measures, whenever individually are used alone, the benefits received are very small and may become infective with time.  On other hand, in an integrated approach, when different ways of virus management measures are combined and used together, there would be effective overall reduction or control of virus and sub-viral diseases.  Integrated virus management strategies are to be comprehensive, effective and should protect farmers from economic hardships due to crop losses because of virus and virus-like diseases.  The virus management strategies developed must be robust and involve minimum extra expenditure.  This book is an excellent latest source of information for those interested in plant virus teaching, research and virus management.  It is also invaluable resource for research workers, educators, students of plant virology, plant pathology, plant breeding, biotechnology, molecular biology.
