Plant development and defence are intimately connected to programmed cell death (PCD). PCD can occur after environmental cues such as pathogen infection, mechanical damage or abiotic stress. However, PCD also constitutes an essential feature of various aspects of growth and development. Despite the differences in stimuli, the subsequent steps leading to programmed cellular death show considerable commonality, reflecting the essential and overlapping roles of individual regulatory components in these processes. These components can function as positive or negative regulators and can have contrasting functions depending on the form of cell death.
植物的发育和防御与程序性细胞死亡（PCD）密切相关。PCD可在病原体感染、机械损伤或非生物胁迫等环境信号后发生。然而，PCD也是生长和发育各个方面的一个基本特征。尽管刺激因素存在差异，但导致程序性细胞死亡的后续步骤显示出相当大的共性，这反映了各个调控成分在这些过程中的重要且重叠的作用。这些成分可以作为正调控因子或负调控因子发挥作用，并且根据细胞死亡的形式可能具有相反的功能。
