水杨酸介导的植物系统获得抗性信号的传导途径

摘要/Abstract

摘要： 水杨酸(SA)是植物系统获得抗性(SAR)所必需的内源信号分子，在介导SAR的信号传导中起着十分重要的作用，这一点已经在烟草、黄瓜和拟南芥等植物中得到证实。水杨酸结合蛋白(SABP)与过氧化氢酶的活性相似，其与SA结合能抑制过氧化氢酶的活性，使植物细胞中过氧化氢水平升高，促使SAR的产生。病程相关基因非表达子1(NPR1)是在SAR信号转导途径中的关键性调控因子。

Abstract: Salicylic acid is a necessary endogenetic signal molecule of systemic acquired resistance (SAR) in plant. It has very important effect in mediating signal transduction of SAR. This has been substantiated in tobacco, cucumber and Arabidopsis et al. Salicylic acid-binding-proteins (SABP) have similar activity with catalase. Coalesce of SABP and SA can restrain the activity of catalase, make the content of hydrogen peroxide solution hoist, and accelerate the occurrence of SAR. Nonexpressor of pathogenesis-related genes 1(NPR1) is a key regulation gene in the signal transduction of SAR.
