Role of Salicylic Acid in Plant Disease Resistance
水杨酸在植物抗病中的作用

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.
