Examine the most recent developments in molecular plant pathology!This comprehensive reference book describes the molecular biology of plant-pathogen interactions in depth. With Dr. Vidhyasekarans keen insights and experienced critical viewpoint, Bacterial Disease Resistance in Plants: Molecular Biology and Biotechnological Applications not only presents reviews of current research but goes on to suggest future research strategies to exploit the studies in interventions with biotechnological, commercial, and field applications.This extraordinarily well-referenced book delivers in-depth examinations of: the molecular recognition process between plants and bacterial pathogens bacterial genes involved in the recognition process hrp, avr, dsp, and hsv genes the transcription of bacterial genes in plants signal transduction systems in bacteria and plants the functions of resistance genes and defense genes at the molecular level the elicitor molecules of bacterial pathogens and plants and their interactions plant and bacterial cell wall modifications and their role in triggering host defense mechanismsBacterial Disease Resistance in Plants also explores active oxygen species, inducible plant proteins and their signals and transcription mechanisms, inducible secondary metabolites, and more. It introduces novel strategies for bacterial disease management using genes from human beings, birds, crabs, insects, fungi, bacteria, and bacteriophages; and genetic engineering techniques that can be used to develop transgenic, disease-resistant plants.Generously illustrated with figures and tables that make the data more quickly understandable, Bacterial Disease Resistance in Plants will be an invaluable resource and textbook for plant pathologists, bacteriologists, botanists, plant physiologists, plant molecular biologists, microbiologists, biochemists, plant cell and applied biologists, genetic engineers, and graduate-level students in these disciplines.
