Book Physiology and Biochemistry of Plant Pathogen Interactions

Download or read book Physiology and Biochemistry of Plant Pathogen Interactions written by I. J. Misaghi and published by Springer Science & Business Media. 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).

Book Specificity in Plant Diseases

Download or read book Specificity in Plant Diseases written by R. K. S. Wood and published by Springer. This book was released on 1976-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: A NATO Advanced Study Institute on "Phytotoxins in Plant Diseases" was held in Pugnochiuso (Italy) in June 1970. It was concerned mainly with the chemistry and mode of action of substances toxic to higher plants which are produced by pathogenic bacteria and fungi. The role of such substances in specificity was consider ed but largely in relation to host-specific toxins. In 1973, in light of the success of the 1970 Institute, we decided to plan for another in 1975 and after discussion with col leagues during the Second International Congress of Plant Pathology, we selected "Specificity in Plant Diseases" as the theme for the 1975 Institute. Our chief reasons for the choice were that specificity is un doubtedly the dominant problem in plant pathology and that with the rapid increase during the last decade or so in the diversity and sophistication of biochemical techniques, we should now expect during the next few years much more research on specificity and major ad vances in our understanding of the mechanisms that control it. It seemed to us that a residential meeting with the advantages and status of a NATO Advanced Study Institute would do much to stimulate interest and research in this most important field. The theme also had the merit of continuity with that of the 1970 Institute.

Book Genes Involved in Microbe Plant Interactions

Download or read book Genes Involved in Microbe Plant Interactions written by D.P.S. Verma and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interdependence between species is a law of nature. The degree of this interdependence is vividly evident in the plant-microbial world. Indeed, there is no axenic plant in nature and one finds various forms of interac tions between these two kingdoms ranging from completely innocuous to obligate parasitic. Most of these interactions are poorly understood at the molecular and physiological levels. Only those few cases for which a molecular picture is emerging are discussed in this volume. With the advent of recombinant DNA technology and the realization that some of these interactions are very beneficial to the host plant, a spate of activity to understand and manipulate these processes is occurring. Microbes interact with plants for nutrition. In spite of the large number of plant-microbe interactions, those microbes that cause harm to the plants (i. e. , cause disease) are very few. It is thus obvious that plants have evolved various defense mechanisms to deal with the microbial world. The mecha nisms for protection are highly diverse and poorly understood. Some pathogens have developed very sophisticated mechanisms to parasitize plants, an excellent example for this being crown gall caused by a soil bac terium, Agrobacterium tumefaciens. A remarkable ingenuity is exhibited by this bacterium to manipulate its host to provide nitrogenous compounds which only this bacterium can catabolize. This is carried out by a direct gene transfer mechanism from bacteria to plants.

Book Plant Disease  An Advanced Treatise

Download or read book Plant Disease An Advanced Treatise written by James G. Horsfall and published by Elsevier. This book was released on 2012-12-02 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Disease An Advanced Treatise, Volume V: How Plants Defend Themselves describes the active, passive, physical, chemical, mechanical, and physiological defense systems of plants against the pathogens. Divided into 23 chapters, this volume discusses theories, experimental approaches, and ways to help plant defend themselves. The opening chapters of this volume deal with certain general aspects of plant defense, such as the theories of “tolerance to disease and “the time sequence of defense , including a dynamic model of defense. A chapter discusses how plant populations defend themselves in natural ecosystem and the implications of disease management on agroecosystems. Considerable chapters examine the defense by the host by analogy with defense of a medieval castle, such as perimeter, internal, and chemical defenses. Discussions on the defenses triggered by the invading pathogen; recognition and compatibility phenomena; the concept of hypersensitivity; the role of phytoalexins in defense; and the metabolic detoxification done by plants to suffer less damage from toxins are provided. This volume also discusses the theory and mechanisms of hypovirulence and hyperparasitism. The concluding chapters summarize the effects of numerous nutrients on disease and the mechanisms involved. This volume is an invaluable source for plant pathologists, mycologists, advanced researches, and graduate students.

Book Host Pathogen Interactions in Plant Disease

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.

Download or read book Bacterial Adherence written by C. Beachey and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacteria adhere to and colonize almost any surface. Within minutes after sub merging a solid object in seawater or freshwater, the surface becomes colonized by adherent micro-organisms, and the earliest organisms to adhere are bacteria. Adherent colonies of bacteria have also been observed on particles of sand, soil, other bacteria, plant tissues, and a variety of animal tissues. Shortly after birth, the skin and the mucosal surfaces of the upper respiratory tract and the gastro intestinal tract of animals and man become heavily colonized by a variety of adherent bacteria which persist in varying numbers as indigenous parasites. The apparent symbiotic balance between the host and his indigenous parasites oc casionally is upset by the invasion of harmful bacteria which adhere to and colonize these surfaces. Pathogenic bacteria may also adhere to and colonize normally sterile surfaces such as the mucosa of the genito-urinary tract and the lower respiratory tract, and occasionally even endothelial surfaces of the cardiovascular system, resulting in the development of serious infectious diseases. Although marine microbiologists have been aware for a long time that bacteria must stick to surfaces in order to avoid being swept away by moving streams of water, not until recently has it been widely recognized that adherence must be an important ecological determinant in the colonization of specific sites in plants and animals, and in particular an important early event in the pathogenesis of bacterial infections in animals and man. It is true that Dr G.
