Phytopathogenic Prokaryotes, Volume 2, provides an understanding of the diversity and complexity of diseases caused by these organisms. It is part of a two-volume treatise that summarizes current research on phytopathogenic prokaryotes. The book is organized into five parts. Part I describes the movement of pathogens from one host to another. The concepts to be presented are essential for understanding the epidemiology and, therefore, the control of diseases caused by prokaryotes. Parts II and III elaborate on the dynamic nature of host/parasite interaction. First to be presented are methods by which hosts may evolve to minimize damage caused by their pathogens. Second, the mechanisms for rapid genetic change available to the pathogen to counteract host defenses are discussed. Part IV emphasizes control of diseases caused by prokaryotes. Manipulation of plant-prokaryote interactions to break the disease cycle or minimize losses is discussed in regard to cultural practices, host breeding, biological control, and chemical control. Part V deals with cultivation and preservation of phytopathogenic prokaryotes.
