Programmed cell death (PCD) is a physiological process that is part of the life of all organisms. In plants and animals, PCD is essential for normal development and for the removal of damaged or infected cells. Different types of PCD have been described in plant cells in response to developmental cues, pathogen infection or abiotic stresses. One example of PCD may occur on infected leaves at the site of pathogen entry (the so-called "hypersensitive response") to limit pathogen spread. This response is generally associated with the induction of a specific disease resistance mechanism in the plants.

程序性细胞死亡（PCD）是一种生理过程，是所有生物生命的一部分。在植物和动物中，PCD对于正常发育和清除受损或感染的细胞至关重要。不同类型的PCD已被描述在植物细胞中响应于发育线索、病原体感染或非生物胁迫。PCD的一个例子可能发生在病原体进入部位的受感染叶片上（所谓的“过敏反应”），以限制病原体传播。这种反应通常与植物中特定抗病机制的诱导有关。
