摘　　要：系统获得抗性(systemic acquired resistance, SAR)是植物受到病菌侵染后诱导产生的一种防御机制,表现为系统性广谱抗性。SAR中通常在侵染部位产生多种可移动的系统信号,转运到植株其余部位,并激活系统性防卫反应。本文综述了水杨酸和水杨酸甲酯、哌啶酸和N-羟基哌啶酸、壬二酸、甘油三磷酸、萜类物质(脱氢枞醛、松萜)等系统信号在SAR中的合成、功能、转运、作用机制及其相互关系。Systemic acquired resistance(SAR) is a defense mechanism induced by local infection of pathogens, conferring broad-spectrum resistance within the whole plants. During SAR, a variety of systemic signals are generated at the primary infection site and transported to the distal parts of the plants, leading to the systemic activation of defense responses. This review summarizes the recent progress on the function, transport, mechanism and relationship of SAR systemic signals including salicylic acid and methyl salicylate, pipecolic acid and N-hydroxypipecolic acid, azelaic, glycerol-3-phosphate, and terpene compounds(dehydroabietinal and pinenes).
