摘要：细胞程序性死亡是由某些特定基因调控的,在细胞生长发育或对外界刺激的反应过程中表现出来的一种生物学过程,伴随着细胞形态学及分子生物学等方面的特征。其中,植物过敏性反应是细胞程序性死亡的重要表现形式之一,表现为植物在不亲和病原菌侵染下受侵细胞及邻近细胞的快速死亡,从而导致病原菌生长受抑制,HR过程对于植物抗病性有重要意义。目前,关于抗病过程中的PCD和HR的研究已成为植物病理学的重点和热点之一。本文综述了植物抗病过程中PCD及HR的研究进展,重点对植物HR特征、可能的信号传导因子、检测方法、产生的分子机制等方面进行了分析和总结,并对林木抗病中的PCD研究进行了展望。
Programmed cell death （PCD） is a biological process regulated by some specific genes in cell growth or response to stimulation outside, along with the characteristics of Cell morphology and molecular biology. Plant hypersensitive response （HR） is a type of PCD and also a form of disease resistance induced by the incompatible pathogen with a rapid death of the infected cells and their surrounding to restrict the pathogen growth. Hypersensitive cell death is not caused directly by the destructive potential of the pathogen, but rather under an intrinsic genetic control, i. e., a type of programmed cell death （PCD）. HR is the key to the plant resistance to diseases. Research on HR has become one of the focuses and hot spots in phytopathology. In this paper we reviewed and discussed the development of HR on plant disease resistance, especially its characteristics, information conduct factors, monitoring methods and molecular mechanisms. In the end, we put forward a prospect for application of PCD in forest plant disease resistance.
