Book Description :

Viruses: Molecular Biology, Host Interactions, and Applications to Biotechnology provides an up-to-date introduction to human, animal and plant viruses within the context of recent advances in high-throughput sequencing that have demonstrated that viruses are vastly greater and more diverse than previously recognized. It covers discoveries such as the Mimivirus and its virophage which have stimulated new discussions on the definition of viruses, their place in the current view, and their inherent and derived ‘interactomics’ as defined by the molecules and the processes by which virus gene products interact with themselves and their host’s cellular gene products. Further, the book includes perspectives on basic aspects of virology, including the structure of viruses, the organization of their genomes, and basic strategies in replication and expression, emphasizing the diversity and versatility of viruses, how they cause disease and how their hosts react to such disease, and exploring developments in the field of host-microbe interactions in recent years. The book is likely to appeal, and be useful, to a wide audience that includes students, academics and researchers studying the molecular biology and applications of viruses Provides key insights into recent technological advances, including high-throughput sequencing Presents viruses not only as formidable foes, but also as entities that can be beneficial to their hosts and humankind that are helping to shape the tree of life Features exposition on the diversity and versatility of viruses, how they cause disease, and an exploration of virus-host interactions

Book Description :

Virus-host interactions are complex and have been a driving force of the everlasting evolutionary progress of both virus and host. Ever since the first virus infection took place, it has been an arms race of defense and counter defense between virus and host. To further uncover the underpinnings of this arms race, plant RNA viruses were utilized to uncover the mechanisms of virus-host interactions. Three projects were chosen that focus on different aspects of the viral interaction. Specifically, three separate projects investigated viral-host relationships in suppression activities of the viral proteins, coat protein's trans effect on recombination, and co-encapsidation of host-RNA. The first project focused on the host effect on the virus through the RNA silencing system that can degrade viral RNA. Additionally, the possibility that virus-host interactions might provide an evolutionary advantage in favor of the host was investigated.

Book Description :

Plant RNA– and DNA-viruses have small genomes and with this limited coding capacity exhibit a strong dependency on host cellular processes and factors to complete their viral life cycle. Various interactions of viral proteins or nucleic acids with host components (proteins, nucleic acids, carbohydrates, lipids and metabolites) evolved, which are essential for a successful systemic spread of viruses within the plant. For example, in plants, transport of endogenous macromolecules like proteins and nucleic acids occurs in a highly selective and regulated manner and viruses exploit these specifically controlled trafficking pathways. Research on plant virus movement is located at the interface of molecular plant virology and plant cell biology. The proposed book project aims to give an overview on the current state of this research and to highlight novel insights into the dynamic interplay between plant viruses and host cells. The book is intended for researchers in plant biology and virology and especially written for those who aim to understand cell biology of virus-plant interactions. ​

Book Description :

Plant viruses cause many of the most important diseases threatening crops worldwide. Over the last quarter of a century, an increasing number of plant viruses have emerged in various parts of the world, especially in the tropics and subtropics. As is generally observed for plant viruses, most of the emerging viruses are transmitted horizontally by biological vectors, mainly insects. Reverse genetics using infectious clones-available for many plant viruses-has been used for identification of viral determinants involved in virus-host and virus-vector interactions. Although many studies have identified a number of factors involved in disease development and transmission, the precise mechanisms are unknown for most of the virus-plant-vector combinations. In most cases, the diverse outcomes resulting from virus-virus interactions are poorly understood. Although significant advances have been made towards understand the mechanisms involved in plant resistance to viruses, we are far from being able to apply this knowledge to protect cultivated plants from the all viral threats.The aim of this Special Issue was to provide a platform for researchers interested in plant virology to share their recent results. To achieve this, we invited the plant virology community to submit research articles, short communications and reviews related to the various aspects of plant virology: ecology, virus-plant host interactions, virus-vector interactions, virus-virus interactions, and control strategies. This issue contains some of the best current research in plant virology.

Book Description :

Mechanisms of resistance to plant viruses are diverse, and probably involve different types of recognition events. Often, a cascade of changes affecting broader aspects of defence and metabolism is switched on progressively after the initial recognition event. Virulence, i.e. resistence-breaking behaviour of the virus, involves a failure or alteration of recognition or subsequent signalling. Consequences of these recognition events are the ways in which the pathogenic effects on the host are exerted: formation of visible symptoms and control of plant growth. This volume offers a comprehensive coverage of the recognition and signalling events between plants and viruses whereby the particular attraction of viruses (and viroids) is that they can now be completely defined in molecular terms: they offer excellent opportunities for studying the molecular biology of signalling, and may even provide useful guidelines on how plants and cellular pathogens interact.

Book Description :

The time seems ripe for a critical compendium of that segment of the biological universe we call viruses. Virology, as a science, having passed only recently through its descriptive phase of naming and num bering, has probably reached that stage at which relatively few new truly new-viruses will be discovered. Triggered by the intellectual probes and techniques of molecular biology, genetics, biochemical cytology, and high resolution microscopy and spectroscopy, the field has experienced a genuine information explosion. Few serious attempts have been made to chronicle these events. This comprehensive series, which will comprise some 6000 pages in a total of about 18 volumes, represents a commitment by a large group of active investigators to analyze, digest, and expostulate on the great mass of data relating to viruses, much of which is now amorphous and disjointed, and scattered throughout a wide literature. In this way, we hope to place the entire field in perspective, and to develop an invalua ble reference and sourcebook for researchers and students at all levels. This series is designed as a continuum that can be entered anywhere, but which also provides a logical progression of developing facts and integrated concepts.

Book Description :

Two decades ago, recombinant DNA technology or genetic engineering ushered in a new era in the study of plant viruses. The major breakthrough came in the eighties, primarily due to the development of new methods for RNA reverse transcription and cDNA cloning, along with restriction enzyme mapping and rapid nucleotide sequencing. An information explosion in various molecular aspects of plant viruses was caused by these studies. Current research efforts investigate the study of viral genomes, genetic maps, genes and gene expression, gene products, and genetic basis of virus functions and biological properties. Molecular Biology of Plant Viruses analyzes, collates and reviews such published information. Additionally, it demonstrates the mechanisms of genetic variability; brings out the molecular basis of virus transport in plants and of virus transmission by vectors and of disease symptomatology; and discusses molecular biology of viroids and transgenic plants. It also treats the recently discovered genetic phenomenon of gene silencing and the gene-for-gene interactions between the hosts and plant viruses. Molecular Biology of Plant Viruses is an excellent reference, providing insight into the exciting research developments made in the field.

Book Description :

This book focuses on the evolution of plant viruses, their molecular classification, epidemics and management, covering topics relating to evolutionary mechanisms, viral ecology and emergence, appropriate analysis methods, and the role of evolution in taxonomy. The currently emerging virus species are increasingly becoming a threat to our way of life, both economically and physically. Plant viruses are particularly significant as they affect our food supply and are capable of rapidly spreading to new plant species. In basic research, plant viruses have become useful models to analyze the molecular biology of plant gene regulation and cell-cell communication. The small size of DNA genome of viruses possesses minimal coding capacity and replicates in the host cell nucleus with the help of host plant cellular machinery. Thus, studying virus cellular processes provides a good basis for explaining DNA replication, transcription, mRNA processing, protein expression and gene silencing in plants. A better understanding of these cellular processes will help us design antiviral strategies for plants. The book provides in-depth information on plant virus gene interactions with hosts, localization and expression and the latest advances in our understanding of plant virus evolution, their responses and crop improvement. Combining characterization of plant viruses and disease management and presenting them together makes it easy to compare all aspects of resistance, tolerance and management strategies. As such, it is a useful resource for molecular biologists and plant virologists alike.

Book Description :

Viruses are a huge threat to agriculture. In the past, viruses used to be controlled using conventional methods, such as crop rotation and destruction of the infected plants, but now there are more novel ways to control them. This volume focuses on topics that must be better understood in order to foster future developments in basic and applied plant virology. These range from virus epidemiology and virus/host co-evolution and the control of vector-mediated transmission through to systems biology investigations of virus-cell interactions. Other chapters cover the current status of signalling in natural resistance and the potential for a revival in the use of cross-protection, as well as future opportunities for the deployment of the under-utilized but highly effective crop protection strategy of pathogen-derived resistance.

Book Description :

The research seeks to understand the virus-host plant interactions for cassava brown streak disease (CBSD) caused by two viruses, Cassava brown streak virus (CBSV) and Ugandan Cassava brown streak virus (UCBSV) of the genus Ipomovirus, family Potyviridae. The diversity of six CBSD isolates from the endemic (Kenya, Malawi, Mozambique and Tanzania) and the recently developed epidemic areas (Uganda) of the disease in eastern Africa was studied. Five cassava varieties differing in virus resistance levels; Albert, Columbian, Ebwanateraka, TMS60444 (all susceptible) and Kiroba (tolerant) were graft-inoculated with the UCBSV and CBSV isolates. Based on a number of parameters, the isolates can be grouped into two main categories; severe and milder forms. Transmission of viruses using non-vector modes confirmed that CBSV was sap transmissible from cassava to cassava. Graft-inoculation of infected scions onto CBSD-free cassava plants was the most efficient mode of transmission which resulted in 80 and 100% rate for UCBSV and CBSV respectively. The two virus isolates were not transmitted through contaminated tools and hands. The effect of host-tolerance on virus was investigated in a long-term experiment where three cassava varieties Albert, Kiroba and Kaleso (field-resistant to CBSD) were graft-inoculated with UCBSV and CBSV. The three cassava varieties showed differences in virus movement, symptom development, severity and relative virus titres. The mechanisms of resistance to CBSD were investigated by making cuttings, from various parts of the plants, and a greater number of disease-free plants were generated from cuttings made from Kaleso than Kiroba and Albert. The fecundity of B. tabaci and its ability to transmit the virus were determined and results indicated no significant differences in the ability of the three cassava varieties to support whitefly development. Finally, thermal and chemical treatments of tissue cultured plants were conducted and the combinations of both treatments produced the greatest number of disease-free plants in all three varieties; Kaleso (50%), Kiroba (44%) and Albert (35%). The information generated in this thesis has greatly improved our understanding of the interactions between the three biotic factors; the host, virus and vector in the CBSD-pathosystem, which would be highly useful in designing effective disease management strategies.
