Active Defense Mechanisms in Plants by R. Wood Pdf

A NATO Advanced Study Institute on "Active Defence Mechanisms in Plants" was held at Cape Sounion, Greece, 21 April - 3 May 1981. It succeeded a similar Institute held at Porte Conte, Sardinia in 1975 on "Specificity in Plant Diseases. " What are active defence mechanisms in the context of plant disease in which a plant, the host, may be damaged by a pathogen? Defence mechanisms comprise properties of the host that decrease this damage. The mechanisms are passive when they are independent of the pathogen. They are active when they follow changes in the host caused by the pathogen. Thus for a fungal pathogen, cell walls of a higher plant which are lignified before infection would be a passive defence mechanism if they decreased damage by impeding growth of the fungus. Cell walls known to become lignified as a response to the pathogen would be an active defence mechanism if it were established that this response decreased damage. The papers and discussions at this Advanced Study Institute were about active defence mechanisms in higher plants, mainly econo mically important crop plants, against fungi, bacteria and viruses as pathogens. Taking the microorganisms first it is a truism but one that bears repeating that although plants almost always grow in close association with a wide variety of fungi and bacteria, often of types that can be pathogens, they rarely become diseased, at least not sufficiently so as to attract notice.

Mechanisms of Plant Defense Responses by B. Fritig,M. Legrand Pdf

Research on the mechanisms of plant defense responses to stress and pathogen attack has attracted much attention in recent years. This increasing interest stems from the fact that the tools of molecular biology now enable us to study the molecular basis of old biological concepts such as host-pathogen recognition (and particularly the gene for-gene relationship), hypersensitive cell death and systemic acquired resistance. Our knowledge about avirulence and resistance genes, elicitors, signal transduction and genes involved in plant defense is rapidly expanding. Moreover we are just beginning to test in planta the potential of these results for biotechnological applications, aimed at improving plant resistance to diseases. The 2nd Conference of the European Foundation for Plant Pathology, hosted by the "Societe Fran~aise de Phytopathologie", was devoted to "Mechanisms of plant defense responses" and was held in Strasbourg, France. It brought together over 350 scientists from universities, research institutes and private sectors of 24 countries. Major advances in the areas under study have been reviewed in plenary lectures and are developed in the main articles of this book. Over 160 high-quality posters were presented and are summarized in short articles. Data from outstanding posters, which were discussed after a short oral presentation, are found in extended articles. As a whole the book presents a collection of papers arranged in six sections and reflecting the present day state-of-the-art of research in the field of plant defense reactions.

Induced Responses to Herbivory by Richard Karban,Ian T. Baldwin Pdf

Plants face a daunting array of creatures that eat them, bore into them, and otherwise use virtually every plant part for food, shelter, or both. But although plants cannot flee from their attackers, they are far from defenseless. In addition to adaptations like thorns, which may be produced in response to attack, plants actively alter their chemistry and physiology in response to damage. For instance, young potato plant leaves being eaten by potato beetles respond by producing chemicals that inhibit beetle digestive enzymes. Over the past fifteen years, research on these induced responses to herbivory has flourished, and here Richard Karban and Ian T. Baldwin present the first comprehensive evaluation and synthesis of this rapidly developing field. They provide state-of-the-discipline reviews and highlight areas where new research will be most productive. Their comprehensive overview will be welcomed by a wide variety of theoretical and applied researchers in ecology, evolutionary biology, plant biology, entomology, and agriculture.

Genes Involved in Plant Defense by Thomas Boller,Frederick Meins Pdf

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.

Induced Resistance for Plant Defence by Dale Walters,Adrian C. Newton,Gary Lyon Pdf

Plant diseases worldwide are responsible for billions of dollarsworth of crop losses every year. With less agrochemicals being usedand less new fungicides coming on the market due to environmentalconcerns, more effort is now being put into the use of geneticpotential of plants for pathogen resistance and the development ofinduced or acquired resistance as an environmentally safe means ofdisease control. This comprehensive book examines in depth the development andexploitation of induced resistance. Chapters review currentknowledge of the agents that can elicit induced resistance,genomics, signalling cascades, mechanisms of defence to pests andpathogens and molecular tools. Further chapters consider thetopical application of inducers for disease control, microbialinduction of pathogen resistance, transgenic approaches, pathogenpopulation biology, trade offs associated with induced resistanceand integration of induced resistance in crop protection. The bookconcludes with a consideration of socio-economic driversdetermining the use of induced resistance, and the future ofinduced resistance in crop protection.

Mechanisms of Resistance to Plant Diseases by R.S. Fraser Pdf

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.

Innate Immunity of Plants, Animals and Humans by Holger Heine Pdf

All living organisms are in a constant battle against their environment. Since uncontained microorganisms would simply overgrow all higher animals, the evolution of multicellular organisms required adequate and efficient defense mechanisms to protect their own integrity and to ensure their own survival. These defense mechanisms, encompassing receptor proteins that sense the presence of pathogens and effector molecules that are involved in controlling them, are the elemental parts of the innate immune system. For many species, the innate immune system is the sole active defense system. Long thought to be an unspecific immune response, the discovery of the Toll-like receptors and their ligands finally revealed just how specific the innate immune response actually is. This book wants to give an overview of our current knowledge about the innate immune system of plants, animals and humans. It not only covers the innate immune mechanisms and responses of so diverse organisms such as plants, Cnidaria, Drosophila, urochordates and zebrafish, but also the major receptor systems in mammalians and humans as well as the central defense mechanisms, antimicrobial peptides and the complement system.

Medicinal Plants and Environmental Challenges by Mansour Ghorbanpour,Ajit Varma Pdf

This book sheds new light on the role of various environmental factors in regulating the metabolic adaptation of medicinal and aromatic plants. Many of the chapters present cutting-edge findings on the contamination of medicinal plants through horizontal transfer, as well as nanomaterials and the biosynthesis of pharmacologically active compounds. In addition, the book highlights the impacts of environmental factors (e.g., high and low temperature, climate change, global warming, UV irradiation, intense sunlight and shade, ozone, carbon dioxide, drought, salinity, nutrient deficiency, agrochemicals, waste, heavy metals, nanomaterials, weeds, pests and pathogen infections) on medicinal and aromatic plants, emphasizing secondary metabolisms. In recent years, interest has grown in the use of bioactive compounds from natural sources. Medicinal and aromatic plants constitute an important part of the natural environment and agro-ecosystems, and contain a wealth of chemical compounds known as secondary metabolites and including alkaloids, glycosides, essential oils and other miscellaneous active substances. These metabolites help plants cope with environmental and/or external stimuli in a rapid, reversible and ecologically meaningful manner. Additionally, environmental factors play a crucial role in regulating the metabolic yield of these biologically active molecules. Understanding how medicinal plants respond to environmental perturbations and climate change could open new frontiers in plant production and in agriculture, where successive innovation is urgently needed due to the looming challenges in connection with global food security and climate change. Readers will discover a range of revealing perspectives and the latest research on this vital topic.
