Jasmonates in Plant Defense Responses

摘要: Plants constantly interact with a wide range of life-threatening organisms including herbivorous arthropods and pathogenic microbes. The plant fatty acid–derived jasmonates produced in response to biotic stresses are essential survival. These oxylipins constitute part the plant’s sophisticated strategy defend itself. Upon attack, increased accumulation these metabolites diverts energy away from growth needs channels it toward defense. complex interplay between invader-specific elicitors provides gene expression regulatory potential launch effective responses against invaders. Such can be either direct, by producing molecules that toxic invading organisms, or indirect, attracting natural enemies such Jasmonates also critical components mediating stress-induced systemic signal(s) activate defense-related genes. availability jasmonate mutants has been crucial identifying roles play stress responses. In this chapter, we present an overview function insect pathogen defense, cross talk other phytohormones fine-tuning defenses, possible role mechanoresponses.
