“…The potential of jasmonates to protect plants from infection by pathogens has been shown before for the interactions between potato and Phytophthora infestans (23), between cotton and Verticillium dahliae (24), and between Arabidopsis and Pythium mastophorum (25). On the other hand, MeJA failed to protect wheat against the powdery mildew fungus Erysiphe graminis (26), whereas SA-mimicking compounds such as INA and benzothiadiazole conferred effective protection (18,26).…”

The endogenous plant hormones salicylic acid (SA) and jasmonic acid (JA), whose levels increase on pathogen infection, activate separate sets of genes encoding antimicrobial proteins in Arabidopsis thaliana. The pathogeninducible genes PR-1, PR-2, and PR-5 require SA signaling for activation, whereas the plant defensin gene PDF1.2, along with a PR-3 and PR-4 gene, are induced by pathogens via an SA-independent and JA-dependent pathway. An Arabidopsis mutant, coi1, that is affected in the JA-response pathway shows enhanced susceptibility to infection by the fungal pathogens Alternaria brassicicola and Botrytis cinerea but not to Peronospora parasitica, and vice versa for two Arabidopsis genotypes (npr1 and NahG) with a defect in their SA response. Resistance to P. parasitica was boosted by external application of the SA-mimicking compound 2,6-dichloroisonicotinic acid [Delaney, T., et al. (1994) Science 266, 1247-1250] but not by methyl jasmonate (MeJA), whereas treatment with MeJA but not 2,6-dichloroisonicotinic acid elevated resistance to Alternaria brassicicola. The protective effect of MeJA against A. brassicicola was the result of an endogenous defense response activated in planta and not a direct effect of MeJA on the pathogen, as no protection to A. brassicicola was observed in the coi1 mutant treated with MeJA. These data point to the existence of at least two separate hormone-dependent defense pathways in Arabidopsis that contribute to resistance against distinct microbial pathogens.

“…Together with recent evidence (Reinbothe et al, 1992), our results indicate that, in barley, jasmonates are involved in mediating forms of stress such as desiccation but are not primarily involved in mediating responses to pathogen attack. The situation might be different in dicots, where jasmonates were found to cause not only local, but also systemic, protection against a fungal pathogen (Cohen et al, 1993). Further studies, e.g.…”

“…JA and Ме-JA induce the synthesis of proteinase inhibitors and are involved in alkaloid release and accumulation, provide a selective suppression of the polypeptide synthesis [7,58]. Generating the formation of active forms of oxygen and stimulating the synthesis of some protective compounds related with pathogene sis JA induces plant disease resistance [84]. JA was found to be involved in signaling from the surface of an infected cell to the nucleus as well as in intercellular signaling, it promotes the protective genes expression [4,7,8,85].…”
