Plants can develop local and systemic wide-spectrum resistance induced by pathogens or by some chemical products, a phenomenon known as systemic acquired resistance (SAR). Non-pathogenic microbes or some elicitors can also induce resistance called induced systemic resistance (ISR). Plant growth regulators (e.g., jasmonates, salicylates, ethylene) play an important role in induction of these systemic resistance types. Jasmonic acid (JA) and its methyl ester (MeJA) as well as ethylene are thought to be important components of the signaling pathway regulating ISR response in plants, while salicylic acid (SA) and its methyl ester (MeSA) are required for induction of SAR. This review will focus on the present knowledge about the role of jasmonates in the induction of plant resistance induction against pathogens and their relation to ethylene and salicylates in the process.
