发育性细胞程序性死亡(DPCD)在植物生长发育中具有多种功能，具有重要的工业生产价值。其中，木质部dPCD形成的木材是应用最广泛的天然材料之一。因此，深入探讨植物DPCD的分子机制具有重要意义。DPCD过程受到遗传网络的严格调控，并参与信号分子的转导。在不同的生物体和个别PCD事件中已经确定了几个关键的调节因子。然而，控制植物dPCD的复杂分子网络仍然非常难以捉摸，这一过程的原始触发因素仍然未知。本文综述了dPCD在营养和生殖发育过程中的转录调控和信号转导的研究进展。希望这篇综述将提供一个关于dPCD在植物不同发育过程中的分子调控的整体观点，并确定调控这些dPCD事件的具体机制。此外，通过在特定的过程中操纵dPCD，如木素合成，可以改善植物在工业生产中的应用。
Developmental programmed cell death (dPCD) has multiple functions in plant growth and development, and is of great value for industrial production. Among them, wood formed by xylem dPCD is one of the most widely used natural materials. Therefore, it is crucial to explore the molecular mechanism of plant dPCD. The dPCD process is tightly regulated by genetic networks and is involved in the transduction of signaling molecules. Several key regulators have been identified in diverse organisms and individual PCD events. However, complex molecular networks controlling plant dPCD remain highly elusive, and the original triggers of this process are still unknown. This review summarizes the recent progress on the transcriptional regulation and signaling of dPCD during vegetative and reproductive development. It is hoped that this review will provide an overall view of the molecular regulation of dPCD in different developmental processes in plants and identify specific mechanisms for regulating these dPCD events. In addition, the application of plants in industrial production can be improved by manipulating dPCD in specific processes, such as xylogenesis.
