摘要：

以H2O2为代表的活性氧(reactive oxygen species, ROS)和以促细胞分裂原活化蛋白激酶(mitogen-activated protein kinase,MAPK)为代表的蛋白激酶广泛存在于植物细胞并参与各种生理反应过程。生物胁迫条件下,一些MAP激酶特异性地调节氧化猝发(oxidative burst, OXB)和过敏反应(hypersensitive response,HR),水杨酸 (salicylic acid,SA)诱导的MAP激酶(SA-induced protein kinase,SIPK)和ROS共同参与系统获得性抗性(systemic acquired resistance,SAR)的建立;SIPK、P38MAPK等分别与H2O2共同调节臭氧、受伤和渗透胁迫等多种非生物胁迫生理反应。ROS和MAP激酶共同调节植物胁迫信号转导,但其机制尚需进一步的研究。
