在其个体发育过程中，植物不断地暴露于各种非生物胁迫因素，这些因素可以损害组织并危及生物体的生存，除非适当地对抗。虽然动物可以简单地逃脱，从而逃避压力，植物作为固着生物已经发展出复杂的策略来抵御它们。当有害因子的强度很高时，植物采用的防御程序之一是诱导程序性细胞死亡（PCD）。这是一个主动的、遗传控制的过程，其启动以隔离和去除受损组织，从而确保生物体的存活。PCD诱导的机制通常包括活性氧（ROS）水平的增加，活性氧被用作应激信号的介质。非生物胁迫诱导的PCD不仅具有重要的生物学意义，而且对农业实践也具有相当大的意义，因为它具有显著影响作物产量的潜力。因此，许多科学企业都集中在阐明导致和控制PCD的机制，以应对植物中的不利条件。这些知识可能有助于开发新的战略，以获得更具弹性的作物品种，提高耐受性和生产力。本文综述了ROS诱导的PCD与非生物胁迫的关系以及细胞器在这一过程中的作用。
During the course of their ontogenesis plants are continuously exposed to a large variety of abiotic stress factors which can damage tissues and jeopardize the survival of the organism unless properly countered. While animals can simply escape and thus evade stressors, plants as sessile organisms have developed complex strategies to withstand them. When the intensity of a detrimental factor is high, one of the defense programs employed by plants is the induction of programmed cell death (PCD). This is an active, genetically controlled process which is initiated to isolate and remove damaged tissues thereby ensuring the survival of the organism. The mechanism of PCD induction usually includes an increase in the levels of reactive oxygen species (ROS) which are utilized as mediators of the stress signal. Abiotic stress-induced PCD is not only a process of fundamental biological importance, but also of considerable interest to agricultural practice as it has the potential to significantly influence crop yield. Therefore, numerous scientific enterprises have focused on elucidating the mechanisms leading to and controlling PCD in response to adverse conditions in plants. This knowledge may help develop novel strategies to obtain more resilient crop varieties with improved tolerance and enhanced productivity. The aim of the present review is to summarize the recent advances in research on ROS-induced PCD related to abiotic stress and the role of the organelles in the process.
