PAMP Signals in Plant Innate Immunity: Signal Perception and Transduction (Signaling and Communication in Plants Book 21)

Plant innate immunity is a potential surveillance system of plants and is the first line of defense against invading pathogens. The immune system is a sleeping system in unstressed healthy plants and is activated on perception of the pathogen-associated molecular patterns (PAMP; the pathogens signature) of invading pathogens. The PAMP alarm/danger signals are perceived by plant pattern-recognition receptors (PRRs). The plant immune system uses several second messengers to encode information generated by the PAMPs and deliver the information downstream of PRRs to proteins which decode/interpret signals and initiate defense gene expression. Activation of the sleeping plant innate immune system by using different biotechnological tools would suppress the development of a wide range of plant pathogens in economically important crop plants. Enhancement of disease resistance through altered regulation of plant immunity signaling systems would be a durable and publicly acceptable technology in plant disease management. This book describes the most fascinating PAMP-PRR signaling complex and signal transduction systems. It also discusses the highly complex networks of signaling pathways involved in transmission of the signals to induce distinctly different defense-related genes to mount offence against different biotrophic, hemibiotrophic, and necrotrophic pathogens.--[Source inconnue] Front Matter....Pages i-xvii Introduction....Pages 1-16 PAMP Signaling in Plant Innate Immunity....Pages 17-161 G-Proteins as Molecular Switches in Signal Transduction....Pages 163-205 Calcium Ion Signaling System: Calcium Signatures and Sensors....Pages 207-282 Reactive Oxygen Species and Cognate Redox Signaling System in Plant Innate Immunity....Pages 283-306 Nitric Oxide Signaling System in Plant Innate Immunity....Pages 307-329 Mitogen-Activated Protein Kinase Cascades in Plant Innate Immunity....Pages 331-374 Phospholipids Signaling System in Plant Innate Immunity....Pages 375-384 Protein Phosphorylation and Dephosphorylation in Plant Immune Signaling Systems....Pages 385-408 Ubiquitin-Proteasome System-Mediated Protein Degradation in Defense Signaling....Pages 409-430 Back Matter....Pages 431-442
