摘要:

植物程序化死亡是植物在生长发育和环境适应过程中的自发性死亡过程,近年来已成为国内外学者关注的热点。大量研究表明,植物程序化死亡进程对植物生长具有重要意义,主要表现为诱导植物细胞死亡来达到改变植物结构特性、启动一系列逆境响应基因等。本文主要从程序化死亡与植物营养生长的关系,程序化死亡的相关信号分子,典型逆境胁迫盐胁迫下程序化死亡的作用及主要采用的研究技术等方面做出了简要综述,最后对程序化死亡的研究方向和发展意义提出了展望。

Abstract: Programmed cell death (PCD) in plants is a kind of the spontaneous cell death events, which commonly occurs in plant developmental process and environmental adaptation. The study of plant PCD has become a hot issue of scholars at home and abroad in recent years. Accumulating evidences show that plant PCD process is tightly associated with plant growth, and this event can help plant change structure property, activate cascade of genes involved in stress-response genes. In this review, recent research progress with respect to the correlation between plant vegetative growth and PCD, the PCD-related signaling molecules, the function of PCD during plant typical adversity stress responses of salt stress and the innovative methods implicated in the plant PCD research. Ultimately, we raised some outlook regarding the trends and significance of PCD investigation in plants.
