摘　　要：发育调节型程序性细胞死亡(d PCD)在植物生长发育进程中具有多种功能。d PCD发生在植物营养生长和生殖发育过程中,通常是特定细胞类型的最终分化步骤。由于提前或延迟的d PCD过程可能会对植物产生不利影响,d PCD过程的执行必须严格控制。d PCD过程由相关遗传网络严格调节,并参与信号分子的转导。在不同的生物体和个体d PCD事件中,已经确定了几个关键的调节因子,然而,控制植物d PCD的复杂分子网络仍然非常难以捉摸。综述了该领域的最新进展,重点介绍了d PCD的功能、相关信号因子及其调控机制,为深入解析其调控网络及未来应用提供理论参考。Developmental programmed cell death(d PCD)has multiple functions in plant growth and development.d PCD occurs during vegetative and reproductive development,often as the final differentiation step of specific cell types.As precocious or delayed d PCD can have detrimental consequences for plant development,the actual execution of d PCD has to be tightly controlled.The d PCD 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 d PCD events.However,complex molecular networks controlling plant d PCD remain highly elusive.This article reviews the recent advances in the field,focuses on the function,related signal factors and regulation mechanism of d PCD,aiming to provide a theoretical reference for in-depth analysis of its regulation network and future application.
