This book was released on 2012-12-06 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant resistance to pathogens is one of the most important strategies of disease control. Knowledge of resistance mechanisms, and of how to exploit them, has made a significant contribution to agricultural productivity. However, the continuous evolution of new variants of pathogen, ana additional control problems posed by new crops and agricultural methods, creates a need for a corresponding increase in our understanding of resistance and ability to utilize it. The study of resistance mechanisms also has attractions from a purely academic point of view. First there is the breadth of the problem, which can be approached at the genetical, molecular, cellular, whole plant or population lev~ls. Often there is the possibility of productive exchange of ideas between different disciplines. Then there is the fact that despite recent advances, many of the mechanisms involved have still to be fully elucidated. Finally, and compared with workers in other areas of biology, the student of resistance is twice blessed in having as his subject the interaction of two or more organisms, with the intriguing problems of recognition, specificity and co-evolution which this raises.

This book was released on 2013-04-18 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Induced or acquired resistance to disease in plants has been known for many years, but the phenomenon was studied in only a few laboratories until about a decade ago. Since then, there has been an increasing interest in induced resistance as a new, environmentally safe means of disease control, as well as a model for the study of the genes involved in host defence and the signals that control them. This increased interest led the editors of Induced Resistance to Disease in Plants to collect and summarise much of the current and older literature on the topic in a single volume. Each chapter covers its topic as comprehensively as possible, thus serving as a solid introduction to the literature, as well as expressing its writer's own views on the state of research in the area and giving an indication of where future research may lead. Induced Resistance to Disease in Plants addresses the biology of induced resistance in legumes, solanaceae, cucurbits and monocots, since these are the families that have received the most attention, followed by a discussion of the molecular basis of induced resistance, its genetic and evolutionary significance, and practical applications in disease control. The book will provide a background for those commencing work in the area, as well as a source of information for established workers who wish to learn about other areas of induced resistance.

This book was released on 1994-07-27 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: An important aspect of successful agriculture is the control of plant diseases that reduce productivity, quality, and profitability. Application of exogenous chemicals and development of endogenous resistance are two general approaches to controlling plant diseases. As the former falls under continued attack and regulation, the latter fortunately becomes more achievable through biotechnology. Biotechnology and Plant Protection: Bacterial Pathogenesis and Disease Resistance explores the application of biotechnology to understanding bacterial pathogenesis and the nature of plant resistance to bacterial disease. More important, the information presented in this volume foreshadows the development of plants with increased native resistance to bacterial disease. Classical plant breeding has made great progress in developing resistant plants through largely empirical approaches, but a direct understanding of the genetic aspects of pathogenesis and resistance will accelerate the process.

Download or read book Disease Resistance in Plants written by J.E. Vanderplank and published by Elsevier. This book was released on 2012-12-02 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Disease Resistance in Plants, Second Edition, looks at genetic, epidemiologic, biochemical, and biometric principles for developing new cultivars possessing genetic resistance to diseases. It examines the nature of disease resistance and resistance genes, and it highlights the importance of stabilizing selection, sugar, biotrophy, and necrotrophy to obtain the greatest possible yields. Organized into 17 chapters, this volume begins with an overview of disease resistance in plants and the ways to develop disease-resistant variants. It then discusses unspecific resistance; the resistance gene paradox; susceptibility and resistance within narrow host taxa; phenotypic variation and gene numbers in host plants; discontinuous variation and cytoplasmic inheritance; and experimental difficulties in partitioning variance. The reader is also introduced to epistasis and the structure of virulence in pathogens; the notion of physiological race; how the pathogen adapts to the host; mutation in the pathogen from avirulence to virulence; horizontal and vertical resistance to disease and its epidemiological effects; and the link between protein polymorphism and vertical resistance. In addition, the book discusses genes for susceptibility in the host versus genes for avirulence (or virulence) in the pathogen; sink-induced loss of resistance; high-sugar disease processes and biotrophy; slow rusting of cereal crops; plant resistance against endemic disease; and the accumulation of resistance genes in heterogeneous host populations. This book will be useful to plant pathologists and plant breeders.
Download or read book Genetics of Plant Diseases written by Jess Bush & and published by Scientific e-Resources. This book was released on 2019-02-20 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant diseases are usually caused by fungi, bacteria and viruses. Also there are other diseases which are caused by adverse environmental conditions. Plant disease resistance protects plants from pathogens in two ways: by pre-formed structures and chemicals, and by infection-induced responses of the immune system. Relative to a susceptible plant, disease resistance is the reduction of pathogen growth on or in the plant, while the term disease tolerance describes plants that exhibit little disease damage despite substantial pathogen levels. Disease outcome is determined by the three-way interaction of the pathogen, the plant and the environmental conditions. Some of the earliest and most prominent uses of genetic modification technology in crops have related to disease management. The insertion of a Bacillus thuringiensis gene into crops such as corn resulted in protection against damage caused by certain insects, eliminating the need for pesticides against those particular pests is one example. Another example, the ability of crops to thrive despite the application of glyphosate, was brought about by modifying crops so that the pathway affected by the chemical to cause plant death is cycled more regularly, helping the crop to survive. The book provides thorough information about bacteria and bacterial plant diseases. It covers history, structure, classification, special DNA characteristics and special activities of bacteria. The book fulfil not only the need of the students to find literature on the diseases and other pathological conditions difficult to obtain and access, but also provide complete systematic treatment of the subject from their point of view.

Download or read book Recent Advances in the Diagnosis and Management of Plant Diseases written by L.P. Awasthi and published by Springer. This book was released on 2015-11-19 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of the most challenging and significant chapters on the diagnosis and management of important bacterial, fungal, viral, viroid, phytoplasma, non parasitic diseases and various physiological disorders, in various crops. The chapters have been contributed by eminent plant pathologists, having wide experience of teaching and research on various crops with different types of diseases, which cause great economic losses. The book would be very useful for students, teachers and researchers of plant pathology. This book highlights recent advances made in the development of new types of resistance in host plants and alternative strategies for managing plant diseases to improve food quality and reduce the negative public health impact associated with plant diseases. Having entered into 21st century advancements in the Diagnosis of Plant Pathogens and Plant Disease Management need to be closely examined and adequately applied, so that newer challenges facing plant pathology could be adequately addressed in attaining food security for the growing population. Substantial advancements have been made in terms of expanding knowledge base of the biology of plant-microbial interactions, disease management strategies and application and practice of Plant Pathology. Application of molecular biology in Plant Pathology has greatly improved our ability to detect plant pathogens and in increasing our understanding, their ecology and epidemiology. Similarly, new technologies and resources have been evolved for the development of sustainable crop protection systems by different control strategies against various pests and pathogens that are important components of the integrated pest management programme. Natural products and chemical compounds discovered as a result of basic research and molecular mechanisms of pathogenesis have led to the development of “biorational” pesticides. Biological control has been found to be the most significant approach to plant health management during the twentieth century and promises using modern biotechnology, to be even more significant in the twenty-first century.
Download or read book Genes Involved in Plant Defense written by Thomas Boller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many fungi and bacteria that associate with plants are potentially harmful and can cause disease, while others enter into mutually beneficial sym bioses. Co-evolution of plants with pathogenic and symbiotic microbes has lead to refined mechanisms of reciprocal recognition, defense and counter defense. Genes in both partners determine and regulate these mechanisms. A detailed understanding of these genes provides basic biological insights as well as a starting point for developing novel methods of crop protection against pathogens. This volume deals with defense-related genes of plants and their regulation as well as with the genes of microbes involved in their interaction with plants. Our discussion begins at the level of populations and addresses the complex interaction of plant and microbial genes in multigenic disease resistance and its significance for crop protection as compared to mono genic resistance (Chap. 1). Although monogenic disease resistance may have its problems in the practice of crop protection, it is appealing to the experimentalist: in the so-called gene-for-gene systems, single genes in the plant and in the pathogen specify the compatibility or incompatibility of an interaction providing an ideal experimental system for studying events at the molecular level (Chaps. 2 and 4). Good progress has been made in identifying viral, bacterial, and fungal genes important in virulence and host range (Chaps. 3-6). An important aspect of plant-microbe interactions is the exchange of chemical signals. Microbes can respond to chemical signals of plant origin.
