Necrotroph.c path.genic bacteria, fungi and oomycetes are widely distributed and are responsible for significant crop losses. h.st plants deploy different defense mech.nisms and appropriate immune responses to defend th.m against th.se path.gens. Regardless of th. path.gen’s lifestyle, infection activates plant immune responses eith.r th.ough.Path.gen/Microbe Associated Molecular Pattern (P/MAMP) or th.ough.Effector Triggered Immunity (ETI). h.wever, as R-genes are not usually associated with.resistance to necrotroph., resistance is largely dependent on th. balanced interplay between crucial ph.toh.rmones in complex signaling path.ays involving jasmonic acid (JA), eth.lene, salicylic acid (SA) and abscisic acid (ABA). An increase in salicylic acid levels enh.nces susceptibility to necrotroph.c path.gens but promotes resistance to h.mibiotroph., wh.reas a deficiency in SA or SA signaling h.s eith.r no significant impact or affects resistance only at th. primary infection site. Th. same fash.on is observed for JA signaling system th.t appears to elicit resistance against diseases caused by necrotroph.c path.gens and can trigger systemic immunity conferring resistance against th.m. On th. oth.r h.nd, ABA can play a positive or negative role in plant defense responses to necrotroph. as ABA-mediated defense responses are dependent on specific plant-path.gen interactions. Understanding plant immune response against necrotroph.c path.gens may lead to th. development of resistant or tolerant crop cultivars.
