摘　　要：综述了由植物病原菌和非病原性的根际促生菌诱导产生的两种植物系统抗性:系统获得性抗性(SAR)和系统诱导抗性(ISR),比较了两类系统抗性的诱导、信号分子和机理的异同点,阐述了信号分子水杨酸在系统获得性抗性诱导过程中的作用及茉莉酸和乙烯在系统诱导抗性产生过程中的作用。There are two different resistance systems in plants that can be induced by plant pathogenic microorganism or nonpathogenic microorganism. One is systemic acquired resistance （SAR） which induced by plant pathogenic microorganism and connected with the signaling molecular salicylic acid （SA）, the other is induced systemic resistance （ISR） which induced by nonpathogenic microorganism and connected with the signaling molecular jasmonic acid （JA）. The differences between SAR and ISR on mechanism of induction and signaling moleculars, and the studies on signal transduction of systemic resistance were described.
