- W944194579 abstract "最早从拟南芥(Arabidopsis thaliana)中克隆到的NPR1(nonexpressor of pathogenesis-related genes 1)基因是调控植物病害抗性的一个关键基因.它不仅对植物系统获得抗性(systemic acquired resistance,SAR)和诱导系统抗性(induced systemicresistance,ISR)起核心调控作用,而且是植物基础抗性(basic resistance)以及由抗病基因(resistance gene,R)决定的抗性的重要调控因子.氧化突发(oxidative burst)造成的强还原势导致NPR1蛋白还原成单体,以及NPR1单体在细胞核内的积累是诱导水杨酸(salicylic acid,SA)介导的PR(pathogenesis-related)基因表达和SAR产生的充分必要条件.NPR1通过与TGA转录因子的相互作用调控PR基因表达.NPR1作为多种信号途径的交叉点,与某些WRKY转录因子和NPR4一起,在调节和平衡SA和茉莉酸信号传导途径中起关键作用.NPR1的这种调控作用在细胞质内进行,通过遗传工程将其用于植物保护有很好的应用前景." @default.
