Induced by methyjasmonate in response to stress Helps in growth of the pathogen. It might also alter flavonoids metabolism. Involved in important pathways which lead to the synthesis of defense related secondary metabolites. Induces cell death network Helps in production of Absissic acid in plants which in turn is a negative regulator of SA pathways. Increased ABA makes plant susceptible to infection. Induced by IAA. Helps in disease development It scavenges H2O2 which is produced in response to stress. APX is inhibited by SA.
