General Information | Comment | Organism |
---|---|---|
malfunction | underexpression by knockout mutation and/or RNAi-mediated silencing of multiple AtMES genes, including AtMES1, -2, -7, and -9, compromises systemic acquired resistance in Arabidopsis and correlated with enhanced accumulation of MeSA in the systemic tissue of systemic acquired resistance-induced plants | Arabidopsis thaliana |

physiological function | SABP2's methyl salicylate esterase activity is required in healthy systemic tissues of infected plants to release the active defense phytohormone SA from methyl salicylate, which serves as a long-distance signal for systemic acquired resistance | Arabidopsis thaliana |
