Download or read book Host-Pathogen Interactions in Plant Disease written by J. E. Vanderplank and published by Elsevier. This book was released on 2012-12-02 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the genetics, biochemistry, and epidemiology of host-pathogen interactions in plant disease, especially as they concern the breeding of crops for disease resistance. It analyzes a wealth of information that has not previously been recorded in other books or reviews. Some of it stems from basic surveys of disease in the field. The analysis of these surveys not only explains a great deal about host-pathogen interactions that was heretofore obscure, but also indicates directions for future research. Other data, from original papers, have now been coordinated for the first time and organized in a way that suggests new areas of research. The book contains more than fifty new tables that integrate data and relate them to general principles of host-pathogen interactions.For plant pathologists and plant breeders concerned with the control of plant disease, the book shows how to manipulate the host and, indirectly, the pathogen in order to control disease. It analyzes records of resistance against disease that time has shown to be stable in an effort to determine what has kept this resistance stable. It also analyzes the structure of virulence in populations of a pathogen, and demonstrates how virulence can be deliberately restricted. The author updates information on the gene-for-gene hypothesis and discusses the numerical and biological implications of the hypothesis. He analyzes the structure of epidemics based on three fundamental variables: the initial inoculum, the progeny/parent ratio of the pathogen, and the latent period. The author concentrates on the progeny/parent ratio - a subject not hitherto probed in detail in the literature - and shows how to determine the type of epidemic that can occur.

Available in PDF, EPUB and Kindle. Book excerpt: In light of the rapidity increasing incidence rate of bacterial and fungal infections with multi-resistant pathogens, the metabolic changes associated with host-pathogen interactions offer one of the most promising starting points for developing novel antibiotics. . Part one of this comprehensive guide describes the metabolic adaptation of pathogenic microbes in humans, while part two points to routes for the development of novel antibiotics. This is volume six of the book series on drug discovery in infectious diseases by Paul Selzer.

This book was released on 2012-12-06 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a significant surge of interest in the study of the physiology and biochemistry of plant host-parasite interactions in recent years, as evidenced by the number of research papers currently being published on the subject. The in creased interest is probably based on the evidence that effective management of many plant diseases is, for the most part, contingent upon a clear understanding of the nature of host-parasite interactions. This intensified research effort calls for a greater number of books, such as this one, designed to compile, synthesize, and evaluate widely scattered pieces of information on this subject. The study of host-parasite interactions concerns the struggle between plants and pathogens, which has been incessant throughout their coevolution. Such in teractions are often highly complex. Pathogens have developed sophisticated of fensive systems to parasitize plants, while plants have evolved diversified defen sive strategies to ward off potential pathogens. In certain cases, the outcome of a specific host-parasite interaction seems to depend upon the presence or efficacy of the plant's defense system. A plant may become diseased when a parasite manages to invade it, unhindered by preexisting defense systems and/or without eliciting the plant's induced resistance response(s). Absence of disease may re flect the inability of the invading pathogen to overcome the plant's defense sys tem(s).

Download or read book Molecular Aspects of Plant-Pathogen Interaction written by Archana Singh and published by Springer. This book was released on 2018-02-15 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book offers an integrated overview of plant–pathogen interactions. It discusses all the steps in the pathway, from the microbe–host-cell interface and the plant’s recognition of the microbe to the plant’s defense response and biochemical alterations to achieve tolerance / resistance. It also sheds light on the classes of pathogens (bacteria, fungus and viruses); effector molecules, such as PAMPs; receptor molecules like PRRs and NBS-LRR proteins; signaling components like MAPKs; regulatory molecules, such as phytohormones and miRNA; transcription factors, such as WRKY; defense-related proteins such as PR-proteins; and defensive metabolites like secondary metabolites. In addition, it examines the role of post-genomics, high-throughput technology (transcriptomics and proteomics) in studying pathogen outbreaks causing crop losses in a number of plants. Providing a comprehensive picture of plant-pathogen interaction, the updated information included in this book is valuable for all those involved in crop improvement.

Download or read book Mechanisms of Resistance to Plant Diseases written by R.S. Fraser and published by Springer Science & Business Media. 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.

Download or read book Plant-Fungal Pathogen Interaction written by Hermann H. Prell and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on the interactions of plants and phytopathogenic fungi has become one of the most interesting and rapidly moving fields in the plant sciences, the findings of which have contributed tremendously to the development of new strategies of plant protection. This book offers insight into the state of present knowledge. Special emphasis is placed on recognition phenomena between plants and fungi, parasitization strategies employed by the phytopathogenic fungi, the action of phytotoxins, the compatibility of pathogens with host plants and the basic resistance of non-host plants as well as cultivar-specific resistance of host plants. Special attention is paid to the gene-for-gene hypothesis for the determination of race-specific resistance, its molecular models and to the nature of race non-specific resistance as well as the population dynamics of plants and the evolution of their basic resistance.
