    摘要:

    植物系统获得抗性是诱导抗性的一种,是植物受到病原物感染后建立的新抗性;水杨酸(SA)是其重要的信号分子;经SA信号转导,可激活NPR1,而NPR1亦可以负反馈调控SA合成;NPR1可进一步与其下游WRKY和TGA等转录因子相互作用,诱导病程相关蛋白基因的表达,最终植物建立了系统获得抗病性;信号分子SA与脱落酸(ABA)、茉莉酸(JA)之间存在复杂的(被)调控平衡关系,从而影响着SAR是否启动。

    Abstract:

    Systematic Acquired Resistance(SAR) of plant is one kind of Induced Acquired Disease Resistance,a new resistance which built in plant after being infected.Salicylic acid(SA) is an important signal molecule of SAR and transcription factor "NPR1" is activated through the signal transduction by SA.On the other hand,NPR1 is also a negative feedback regulation factor of the SA synthesis.NPR1 interacts with down-stream transcription factor "WRKY" and "TGA".Pathogenesis-related proteins are induced and expressed by the regulation of "WRKY" and "TGA",and SAR is built in plant finally.There are complicated positive regulation(negative regulation) balance relations among SA,ABA and JA,so the success activation of SAR will be interfered by these interactions.
