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.
