【Abstract】 Programmed cell death(PCD) is a common phenomenon at the special developing stages in the plants,which is an active dead process of the cells and is controlled by certain genes.The paper introduces the concept,general characters,mechanism of PCD and the differences between PCD and the plants senescence as well as the studying development in such aspects as examining technology.In addition,the paper viewed some problems to be further resolved and the actual significance in the studies in PCD plants.更多还原
