摘　　要：植物细胞死亡分为坏死和程序性死亡。细胞程序性死亡是具有信号或一系列分子参与,并且由细胞内在的死亡程序介导的有序过程。它在植物生长发育和抵御外界胁迫中具有重要作用。简要介绍了植物PCD的特征,对植物PCD中的信号分子和类caspase的作用等进行了综述,并对植物PCD存在的问题进行分析和展望,为深入研究植物PCD提供参考。Plant cell death was mostly caged in two semantic categories,necrosis and programmed cell death.Programmed cell death（PCD）define any form of cell death involving a single or a series of molecular and cellular orderly processes mediated by intracellular death programs.It plays an important role in normal development,resistance to environmental stress in plant.This article gave a brief introduction of the characters of PCD in plants and summarized the transduction pathway regarding PCD signal and the importance of caspase-like in this process.Some problems to be further resolved in the field of PCD research were discussed,thus it could provide references to further study PCD of plant.
