Up-to-date, accurate information on recent developments in crop protection! Fungal Disease Resistance in Plants: Biochemistry, Molecular Biology, and Genetic Engineering presents the latest developments in crop protection from fungal infection. Leading experts in botany, plant breeding, and plant pathology contribute their knowledge to help reduce and possibly prevent new outbreaks of devastating crop epidemics caused by fungi. With exciting new advances in molecular biology, biochemistry, and genetic engineering, this informative book will help researchers, professors, and students further their understanding of plant defenses. Fungal Disease Resistance in Plants is your guide to understanding the various barriers that plants have developed through evolution and adaptation to protect themselves from invading fungal pathogens. Defenses include physical barriers such as thick cell walls and chemical compounds expressed by the plant when attacked. Still other plants have acquired proteins that play an important role in defense. This book discusses these evolutionary traits and introduces new scientific techniques to engineer resistance in plants that have no built-in protection. Fungal Disease Resistance in Plants explores: cellular expression of resistance to fungal pathogens the hypersensitive response and its role in disease resistance induced plant resistance to fungal pathogens—mechanisms and practical applications pathogenesis-related proteins and their roles in resistance to fungal pathogens signal transduction—plant networks, delivery, and response to fungal infection fungus genes as they relate to disease susceptibility and resistance Without intense research and scientific study, catastrophic harvest failures due to fungal diseases could cause food shortages, human and animal poisonings, and economic loss throughout the world. Augmented with tables, figures, and extensive references, this state-of-the-art source of research material is valuable for scientists and researchers in universities, private organizations, government institutions, and agricultural organizations interested in plant defenses and future crop preservation.

Fungal Wilt Diseases of Plants focuses on wilt diseases caused by the fungal genera Verticillium, Fusarium, and Ceratocystis. Special attention is given to the interactions of physiological, biochemical, and anatomical factors, as these relate to pathogenesis and mechanisms of disease resistance. Organized into 16 chapters, this book begins with a description, in a historical perspective, of the major research themes in fungal wilt diseases. It then looks into the worldwide status of this plant disease. The three subsequent chapters describe the epidemiology and life cycle of the major fungal wilt pathogens in Fusarium, Verticillium, and Ceratocystis. This book also provides an in-depth view of the genetics and biochemistry of these pathogens; the nature of pathogenesis and the effects of wilt pathogens on host-water relations; and the sources and genetics of host resistance in field and fruit crops, vegetable crops, and shade trees. Other chapters are dedicated to the biochemistry, physiology, and the anatomical aspects of resistance and to the progress in the biological and chemical control of these pathogens. This text will be of great value to graduate students and senior research scientists in plant pathology, physiology, and biochemistry, who are specifically involved in studying wilt diseases and host-parasite interactions. It will provide them the detailed background information needed to supplement their specialized research interests.

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 volume offers a comprehensive coverage of the general principles and recent advances in fungicide resistance. It describes the development, mechanisms, monitoring, and management of resistance and covers the most important group of fungicides that have caused resistance on various crops. An historical review of fungicide resistance over the past 40 years sets the scene for up-to-date basic information on mode of action, as well as the genetics, mechanisms, and evolution of resistance. Monitoring for resistance, including the latest developments in molecular diagnostics, moves readers into the practical aspects of resistance management, which is dealt with through a series of case studies outlining fungicide-use strategies on several key crops. The chapters reflect the experience of authors internationally recognised for their significant contributions to fungicide resistance research. The majority of crop diseases are caused by fungal pathogens, and disease control relies heavily on chemically synthesized fungicides. However, modern fungicides often encounter the problem of resistance development in target pathogens. Thus pathogen resistance to fungicides is an important factor that causes loss of yield and quality of crops. It often threatens biosecurity through the decrease of fungicide efficacy in the fields. To manage fungicide resistance successfully will require the promotion of integrated disease management, involving not just chemical fungicides, but also host plant resistance, agronomic factors, and reliable biological control agents where these are available. Well referenced throughout, the book offers a comprehensive account of resistance, which will be useful as a source of material for lecturers and for both industrial and academic scientists involved in fungicide resistance research. It is also a valuable sourcebook for students.

This treatise is focused on early aspects of fungal pathogenesis in plant and animal hosts. Our aim in choosing the topics and contributors was to demonstrate common approaches to studies of fungal-plant and fungal-animal interactions, particularly at the biochemical and molecular Ievels. For example, the initial events of adh«sion of fungal spores to the exposed surface tissues of the host are essential for subsequent invasion of the plant or animal and establishment of pathogenesis. A point of consensus among investigators who have directed their attention to such events in plants, insects, and vertebrates isthat spore adhesion to the host cuticle or epithelium is more than a simple binding event. lt is a complex and potentially pivotal process in fungal-plant interactions which "may involve the secretion of ftuids that prepare the infection court for the development of morphological stages of the germling" and subsequent invasion of the host (Nicholson and Epstein, Chapter 1). The attachment of the fungal propagule to the arthropod cuticle is also "mediated by the chemical components present on the outer layer of the spore wall and the epicuticle . . . . Initial attachment may be reinforced further by either the active secretion of adhesive materials or the modification of spore wall materiallocated at the [fungal spore arthropod] cuticle interface (Boucias and Pendland, Chapter 5).

Studies in the Agricultural and Food Sciences: Plant Breeding for Pest and Disease Resistance presents a critical review of the development of resistant varieties of plant to pests and diseases. It discusses the economic impact of pests and diseases; the methods of controlling these pests and diseases; and the challenges being faced by a plant breeder. Some of the topics covered in the book are the general principles and methods of breeding for resistance; importance of parasite variability to the plant breeder; methods of testing for resistance; requirements for successful inoculation; production of resistant varieties; and economic importance of fungal diseases; and variability in fungal pathogen. Pathogenic fungi and fungal diseases are also covered. The control of fungal diseases by resistant varieties is discussed. An in-depth analysis of diseases in plants is provided. The characteristics of bacteria and bacterial diseases are also presented. A chapter is devoted to epidemiology of diseases associated with mycoplasma-like organisms and rickettsia-like organisms. The book can provide useful information to farmers, botanists, students, and researchers.
