SABP2, a methyl salicylate esterase is required for the systemic acquired resistance induced by acibenzolar‐<i>S</i>‐methyl in plants
説明
<jats:p>Tobacco SABP2, a 29 kDa protein catalyzes the conversion of methyl salicylic acid (MeSA) into salicylic acid (SA) to induce SAR. Pretreatment of plants with acibenzolar‐<jats:italic>S</jats:italic>‐methyl (ASM), a functional analog of salicylic acid induces systemic acquired resistance (SAR). Data presented in this paper suggest that SABP2 catalyzes the conversion of ASM into acibenzolar to induce SAR. Transgenic SABP2‐silenced tobacco plants when treated with ASM, fail to express PR‐1 proteins and do not induce robust SAR expression. When treated with acibenzolar, full SAR is induced in SABP2‐silenced plants. These results show that functional SABP2 is required for ASM‐mediated induction of resistance.</jats:p>
