植物细胞程序性死亡（PCD）已成为现代生物学的一个研究领域。
Programmed cell death in plants is becoming an important research branch of modern biology.
镜下，移植物抗宿主反应是说明“程序性细胞死亡”或单个细胞坏死(即调亡)过程的最好例子。
Microscopically, graft versus host disease is one of the best examples of a process called "apoptosis" or single cell necrosis.
细胞程序性死亡(PCD)是植物体一定发育阶段普遍存在的一种现象，它受特定的基因调控，是主动的细胞死亡过程。
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.
细胞程序性死亡(PCD)是一种由基因控制的、主动的细胞死亡过程，它对植物正常生长发育起重要作用。
Programmed cell death (PCD) is an active and gene-regulated process which plays an important role in normal growth and development of plants.
当这个基因被失活时，植物就不能再调节程序性细胞死亡过程，从而导致整个叶子和植物的死亡。
When the gene is inactivated, the plant can no longer regulate PCD, leading to cell death throughout the leaf and plant.
细胞程序性死亡是在植物体的一定发育阶段普遍发生的受特定基因调控的自然的细胞死亡过程。
Programmed cell death (PCD) is a natural cell death controlled by certain genes, occurring commonly at certain stages of plant development.
