中文摘要：

在植物细胞中，钙离子是普遍存在的第二信使，参与多种信号途径。大量研究表明，钙信使系统参与植物与病原菌互作的信号转导过程。近些年来，特异性钙信号在抗病中的作用越来越受到关注。文章综述了近年来在植物表达防卫反应过程中特异性钙信号的形式及其形成的生理机制的研究进展。

英文摘要：

In plant cell, the calcium ion is a ubiquitous intracellular second messenger involved in numerous signaling pathway. Numerous recent studies have provided evidence that Ca^2＋ plays a pivotal role in activating the plant＇s surveillance system against attempted microbial invasion. Recently, more concentration are payed on the role of specificity of calcium signaling in plant defense response. This article is presented to the latest advancement in the pattern and generation of the specificity of calcium signaling in plant defense response.
