Regulated or programmed cell death (RCD or PCD) is a fundamental biological principle integral to a considerable variety of functions in multicellular organisms. In plants, different PCD processes are part of biotic and abiotic stress responses, but also occur as an essential aspect of unperturbed plant development. PCD is particularly abundant during plant reproduction, eliminating unwanted or no longer needed cells, tissues, or organs in a precisely controlled manner. Failure in reproductive PCD can have detrimental consequences for plant reproduction. Here we shed a light on the latest research into PCD mechanisms in plant reproduction from sex determination over sporogenesis to pollination and fertilization.
程序性细胞死亡（RCD 或 PCD）是多细胞生物中相当多种功能的基本生物学原则。在植物中，不同的 PCD 过程是生物和非生物胁迫反应的一部分，但也作为未受干扰的植物发育的一个重要方面发生。PCD 在植物繁殖过程中特别丰富，以精确控制的方式消除不需要或不再需要的细胞、组织或器官。生殖 PCD 的失败会对植物繁殖产生不利影响。在这里，我们从性别决定到孢子发生、授粉和受精，探讨了植物生殖中程序性细胞死亡机制的最新研究进展。
