摘　　要：由于植物无法逃离逆境,因此进化出高度灵敏而精确的适应机制以应对自然环境中的各种非生物胁迫。当植物局部组织或器官受到非生物胁迫时,通过细胞间信号传递产生系统性反应,使其整体产生对该胁迫的适应性(即系统获得性适应)。目前,大量研究阐明了植物系统获得性适应中细胞间信号传递分子(主要包括活性氧信号、钙信号、电信号、植物激素、磷脂酰肌醇和pH信号)、类受体蛋白激酶以及其它蛋白激酶在系统性信号传递中的作用。该文综述了非生物胁迫引发植物系统获得性适应中细胞间信号传递的研究进展,分析了不同信号之间的可能关系,以期为相关研究提供参考。As plants cannot escape from adversity,they need to evolve highly sensitive and flexible physiological mechanisms to cope with various abiotic stresses in the natural environment.It has been shown that when plants are subjected to abiotic stresses in local tissues or organs,the plant is able to generate systemic responses through intercellular signaling that allows the plant to develop an acclimation to the stress(i.e.,systemic acquired acclimation).Currently,a large amount of work has investigated the role of intercellular signaling molecules in systemic acquired acclimation of plants(mainly including reactive oxygen species signals,calcium signals,electrical signals,plant hormones,phosphatidylinositol,and pH signals)receptor-like protein kinases and other protein kinases in systemic signaling.Here,we mainly review the research progress of intercellular signaling in the abiotic stress-induced systemic responses in plants,and analyze the possible relationships among different signals,so as to provide reference for related research.
