摘要
细胞死亡是动、植物生长发育过程中常见的一种生命现象 ,而细胞程序性死亡 (PCD)是细胞遵循自身生命活动程序 ,并受多种因子调控的一种积极的死亡方式。近年来随着动物中PCD研究的深入 ,植物PCD亦得到相应的研究。植物细胞程序性死亡研究不仅可揭示植物衰老、死亡的内部变化规律 ,而且可为其生长发育的调控提供依据和技术。该文试对有关PCD的特点、研究意义及近年来的研究概况与方法进行简述与评价。
Cell death is a commonly encountered life phenomenon in animals and plants during their growth and development. Programmed cell death (PCD) controlled by multi-factors is an active behaviour of terminating life, which follows itself programme. In recent years, PCD is further researched in animals as well as in plants. A study on PCD in plants not only enunciates their inside changing laws of senescence and death, but also could give a basis and technique to control and regulate their growth and development. Based on above ideas, this article gives a brief introduction of the characters of PCD and its significance, conditions and methods of researches.
