The core components of the jasmonic acid (JA) signaling pathway in rice, tobacco, and Arabidopsis. Jasmonic acid (JA) pathway in plants. Policies. The role of salicylic acid (SA) and jasmonic acid (JA) signaling in resistance to root pathogens has been poorly documented. Other studies have shown that SA is a potent suppressor of JA signaling pathways and JA-dependent defense gene expression in various pharmacological and genetic experiments [ 44 , 45 ]. JA is synthesized via octadecanoic acid pathway where α-Linolenic acid (α-LeA) released from the chloroplast membrane is oxidized by lipoxygenases (LOXs) to form hydroperoxides (9-HPOT and 13-HPOT) ( Ishiguro et al., 2001; Ahmed et al., 2016b ). During these immune responses, plant hormones such as salicylic acid (SA) and jasmonic acid (JA) play important roles in mediating various subsets of defense response events (Spoel and Dong 2008). SA can be synthesized via the phenylpropanoid route or the isochorismate pathway and metabolized to form SA-glucoside and SA glucose-ester through glucosylation . Many forms exist, based on the structure of Jasmonate (jasmonic acid, JA). Fall armyworm (FAW, Spodoptera frugiperda) feeding results in Mir 1-CP accumulation in leaves. Jasmonic acid (JA) is a plant hormone derived from linolenic acid. The jar1-1 mutant exhibited normal trichome induction following treatment with jasmonic acid, suggesting that adenylation of jasmonic acid is not necessary. The first dedicated step in jasmonate biosynthesis is the peroxidation of α-linolenic acid (18:3) by 13-lipoxygenase to form (13S)-hydroperoxyoctadecatrienoic acid (13-HPOT). Ethylene (ET) and jasmonic acid (JA) play important roles in plant defenses against biotic stresses. JA is recognized as a stress hormone that regulates the plant response to biotic stresses such as . Jasmonic acid (JA) and salicylic acid (SA) play important roles in plant defense systems.
