水杨酸(SA)诱导植物对病虫害产生抗性及作用机制研究

Salicylic Acid Induced Resistance of Plants against Insects and Diseases and Its Interaction Mechanism

水杨酸(SA)作为一种新型的抗病性诱导剂,其对植物病虫害的抗性诱导作用已成为研究的热点。本研究从水杨酸的基本性质及其在植物病虫害中的诱导抗性特点、水杨酸与水杨酸结合蛋白的相互作用、水杨酸介导的信号传导途径等方面初步探讨水杨酸诱导植物抗病性和抗虫性的作用机制及应用前景。

Salicylic acid （SA） is a new resistance inducer, and has been a focus in development of SA-induced resistance of plants to diseases and pests. The basic properties and the function of salicylic acid involved in plant resistance to diseases and pests are introduced. The mechanism of salicylic acid in inducing resistance of plants to pest insects and diseases is discussed in terms of interaction of salicylic acid with salicylic acid-binding protein, and salicylic acid-dependent signaling pathway. The prospects for ap plication of SA in inducing resistance of plants to pests and diseases are also made.
