摘要: 水杨酸是一种重要的能激活植物抗病防卫反应的内源信号分子。本文首先介绍了水杨酸的基本性质及水杨酸在植物抗病中的作用,然后从水杨酸与水杨酸结合蛋白的相互作用以及水杨酸介导的信号传导途径与非水杨酸介导的信号途径等方面初步探讨了水杨酸诱导植物抗病性的作用机制,最后总结了研究水杨酸作用机制对植物抗性生理和抗性分子生物学发展的意义。

Abstract: Salicylic acid is an important endogenous signal molecule in the activation of plant defense responses. The basic properties and the function of salicylic acid involved in plant disease resistance are introduced. The operation mechanisms of salicylic acid inducing plant disease resistance have been discussed in the interaction of salicylic acid with salicylic acid_binding protein and salicylic acid_dependent signalling pathway with salicylic acid_independent signalling pathway. Finally, significance of the study on mechanisms of salicylic acid action are summarized.
