Each plant-pathogen interaction involves a two-way molecular communication. On one hand, the pathogen perceives signals from the plant, secretes chemical arsenals to establish infection courts, and produces metabolites that disrupt structural integrity, alter cellular function, and circumvent host defenses. On the other hand, the plant senses the signals from the pathogen, reinforces its cell walls, and accumulates phytoalexins and pathogenesis-related proteins in an attempt to defend itself. The production of pathogenicity and virulence factors by the pathogen, the elicitation of defense mechanisms by the plant, and the dynamic interaction of the two are the focal points of this book. The book will be of interest to researchers and advanced undergraduate and graduate students in the areas of plant pathology, plant physiology, and plant biochemistry.

Investigations on various aspects of plant-pathogen interactions have the ultimate aim of providing information that may be useful for the development of effective crop disease management systems. Molecular techniques have accelerated the formulation of short- and long-term strategies of disease management. Exclusion and eradication of plant pathogens by rapid and precise detection and identification of microbial pathogens in symptomatic and asymptomatic plants and planting materials by employing molecular methods has been practiced extensively by quarantines and certification programs with a decisive advantage. Identification of sources of resistance genes, cloning and characterization of desired resistance genes and incorporation of resistance gene(s) into cultivars and transformation of plants with selected gene(s) have been successfully performed by applying appropriate molecular techniques. Induction of resistance in susceptible cultivars by using biotic and abiotic inducers of resistance is a practical proposition for several crops whose resistance levels could not be improved by breeding or transformation procedures. The risks of emergence of pathogen strains less sensitive or resistant to chemicals have been reduced appreciably by rapid identification of resistant strains and monitoring the occurrence of such strains in different geographical locations.

Genetic and Molecular Basis of Plant Pathogenesis

The new biology is the cement this book uses to bind the literature together. Another feature of this book is an emphasis on thermodynamics.

As befits a volume in the Advanced Series in Agricultural Sciences, this book was written with problems of practical agriculture in mind. One of the ways of controlling plant disease is by using resistant cultivars; and from the wide literature of genetics and biochemistry in plant pathology I have emphasized what seems to bear most closely on breeding for disease resistance. This has a double advantage, for it happens all to the good that this emphasis is also an emphasis on primary causes of disease, as distinct from subsequent processes of symptom expression and other secondary effects. The chapters are entirely modern in outlook. The great revolution in biology this century had its high moments in the elucidation of the DNA double helix in 1953 and the deciphering of the genetic code in 1961. This book, so far as I know, is the first in plant pathology to be conceived within the framework of this new biology. Half the book could not have been written 20 years ago, even if there had then been available all the literature that has since accumulated on the genetics and chemistry of plant disease. The new biology is the cement this book uses to bind the literature together. Another feature of this book is an emphasis on thermodynamics.

Studies on molecular biology of pathogens, infection process and disease resistance, have provided information essentially required to understand the vulnerable stages at which the pathogens can be tackled effectively and to adopt novel strategies to incorporate disease resistance genes from diverse sources and /or to induce resistance of cultivars with desirable agronomic attributes using biotic or abiotic agents. The nature of interaction between the gene products of the pathogen and plant appears to determine the outcome of the interaction resulting in either disease progression or suppression. Transgenic plants with engineered genes show promise for effective exploitation of this approach for practical application. Research efforts during the recent years to sequence the whole genomes of the pathogens and plants may lead to development of better ways of manipulating disease resistance mechanisms enabling the grower to achieve higher production levels and the consumer to enjoy safer food and agricultural products. Experimental protocols included in appropriate chapters will be useful for researchers and graduate students.

Plant Pathogenesis and Disease Control

Environmental pollution resulting from widespread pesticide application has become a serious worldwide problem. Plant Pathogenesis and Disease Control is an important new reference that addresses this problem by exploring the biochemical and molecular mechanisms of plant pathogenesis and emphasizing the use of "pest control agents" rather than "pesticides" for plant disease control. Topics examined include pathogenicity, the resistance of plants against pathogens, the offensive and defensive struggle between hosts and parasites, methods for using natural defense mechanisms to develop environmentally sound disease control agents, and the use of modern biotechnology for plant disease control. The book will be an essential reference for phytopathologists, plant biochemists, pesticide chemists, mycologists, plant cell technologists, and agricultural researchers.

The Advanced Series in Agricultural Sciences is designed to fill a long-felt need for advanced educational and technological books in the agricultural sciences. These texts, intended primarily for students of agriculture, should also provide up-to-date technical background reading for the many agricultural workers in extension services, educational systems, or international bodies. The editors of Advanced Series in Agricultural Sciences will select key subjects relating to the agricultural environment, agricultural physics and chemistry, soil science, plant sciences, animal sciences, food technology, and agricultural engineering for a critical and synthetic appraisal. An initial theoretical presentation will be used by authors of individual volumes in the series to develop a technical approach~including examples and practical solutions~ to each subject. In addressing the advanced undergraduate and early graduate student of agriculture, selected authors will present the latest information, leavened with the lessons learned from their own experience, on precise and well-defined topics. Such books that widen the horizons of the student of agriculture can serve, too, as useful reference sources for the young specialist in the early years of his career. Many specialists who are involved in teaching agricultural science are isolated from universities and research institutions. This series will bring them up-to-date scientific information, thus keeping them in touch with progress. The basic objective of Advanced Series in Agricultural Sciences is to effect a structural integration of the theoretic and technical approaches to agriculture.
