Book Description
This book provides in-depth information on all key aspects of geminivirus biology, e.g. the genetics and evolution, global diversity and spread of these plant pathogens, as well as the molecular mechanisms underlying their virulence. Geminiviridae is one of the largest viral families, comprising numerous plant-infecting viruses that cause diseases in crops and weeds. These diseases have been reported from nearly all continents, in particular Asia, Europe, Africa and America. The book summarizes the current state of knowledge on the interactions between plant host and virus. In addition, it discusses advances regarding the trans-replication of satellite molecules and its effect on geminiviral pathogenesis, as well as pest management strategies to combat these diseases in the field. Given its scope, the book is a must-read reference guide for all researchers and advanced students working in virology, agriculture and plant biotechnology..

Book Description
Concern about the environmental consequences of the widespread use of pesticides has increased, and evidence of pesticide-resistant virus vectors have continued to emerge. This volume presents a timely survey of the mechanisms of plant resistance and examines current developments in breeding for resistance, with particular emphasis on advances in genetic engineering which allow for the incorporation of viral genetic material into plants. Discusses the mechanisms of innate resistance in strains of tobacco, tomato, and cowpea; various aspects of induced resistance, including the characterization and roles of the pathogenesis-related proteins; antiviral substances and their comparison with interferon; and cross-protection between plant virus strains. Also presents several papers which evaluate the status of genetic engineering as it relates to breeding resistant plants. Among these are discussions of the potential use of plant viruses as gene vectors, gene coding for viral coat protein, satellite RNA, and antisense RNA, and practical issues such as the durability of resistant crop plants in the field.

Book Description
The book represents basic information about viral-caused and viral-like diseases in many weeds. Many scientific reports have demonstrated that weeds serve as a reservoir or alternative hosts for geminivirus genera (e.g., Begomovirus) for survival and spread in the absence of main crops. This book represents a tip of the iceberg of the diversity of begomoviruses in weeds. The recognition that geminivirus strains are capable of rapidly diverging through multiple mechanisms, underscores the need for accurate molecularly based methods that permit detection and tracking of biologically significant variants. Molecular approaches must combine knowledge of biology, ecology and the ability to monitor both conserved sequences and specific sites, most likely to undergo alteration with phylogenetic predictions to facilitate accurate identification and tracking of begomovirus variants and to also recognize new or resurgent viruses. Establishing databases of baseline sequences for extant viruses will permit future comparisons in establishing and interpreting disease patterns and associated trends for vector populations. With the development of reliable computational recombination detection tools and an increasing number of available genome sequences, many studies have reported evidence of recombination in a wide range of virus genera. The book also focuses on the first geminivirus database (GVDB) that contains biotic, molecular and in silico information which will permit rapid and accurate begomovirus identification and the selection of relevant viral species for the development of disease resistance/management strategy to the geminiviruses specific to individual crop production areas. To close, there is one chapter on the international and national status of geminivirus infection in various host weeds. Furthermore, the book's heart discusses the most recent cutting-edge of research that makes this book essential reading for everyone, from researchers to scholars to students, working with molecular and computational aspects of geminivirus research as well as scientists already familiar with the area.

Book Description
Begomoviruses are one of the most interesting plant viruses to study for basic and applied research as they cause huge economic losses to agriculture industries and farmers all over the world. They belong to family Geminiviridae and are emergent plant viral pathogens which cause diseases in various crops in the tropical and subtropical regions. They are transmitted by the whitefly (B. tabaci) and have either one (monopartite DNA-A) or two (bipartite DNA-A and DNA-B) genomic components. DNA-A and DNA-B are of ~2600 - 2800 nucleotides each. A number of serious diseases of cultivated crops of the Fabaceae, Malvaceae, Solanaceae and Cucurbitaceae families are caused by Begomoviruses which are considered as threat to their cultivation in many countries. Accurate diagnosis is important for successful diseases management, since plants infected by Begomovirus do not recover, suffer serious yield losses and act as further sources of inoculum, which is then picked up and spread by their vector whitefly (B. tabaci). Reports of occurrence of new viruses and re-emergence of several known viruses in new niches have become regular event. In such a dynamic system, growth of several crop species relies on an accurate diagnosis, management and better understanding of the biology of the casual virus. This is crucial to evolve appropriate control practices and to prevent the virus infection. Researchers have achieved considerable progress in characterization, detection and management of virus on different crop species in the last decade. This book covers latest information in diagnosis of begomoviruses in the present scenario and explores the new vistas in the field of genomics and proteomics. Chapters in Section 1 illustrates the occurrence, genome organisation, transmission and diagnostics of begomoviruses. It also details the diseases caused by begomoviruses on different crops, detection techniques and management strategies in support of research findings by presentation of data, graphics, figures and tables. Section 2 is a chapterwise collection of occurrence, diversity and status of begomoviruses in Asian Africa counties where the diseases are most prevalent. This book will provide wide opportunity to the readers to have complete information and status of begomovirus in Asia and Africa. This will be useful resource for researchers and extension workers involved in the begomvirus disease diagnosis and molecular biology. Expert detection, accurate diagnosis and timely management play a significant role in keeping plants free from pathogens. In this book expert researchers share their research knowledge and literature which are vital towards the diagnosis of begomoviruses, addressing traditional plant pathology techniques as well as advanced molecular diagnostic approach. The book deals with the economically important crops including fruits, vegetables along with challenges in crop protection against diseases caused by begomovirus. This will be resourceful and handy for researcher, practitioners and also students.
