Programmed cell death (PCD) occurs in different tissues in response to a number of different signals in plant cells. Drawing from work in several different contexts, including root-cap cell differentiation, plant response to biotic and abiotic stress, and some self-incompatibility (SI) systems, the data suggest that, despite differences, there are underlying commonalities in the early decision-making stages of PCD. Here, we focus on how 2 cellular events, increased [Ca2+]cyt levels and cytosolic acidification, appear to act as early signals involved in regulating both developmental and stimulus-induced PCD in plant cells.
细胞程序性死亡（PCD）发生在不同的组织中，以响应植物细胞中的许多不同信号。从包括根冠细胞分化、植物对生物和非生物胁迫的反应以及一些自交不亲和（SI）系统在内的几个不同背景的工作中得出的数据表明，尽管存在差异，但在 PCD 的早期决策阶段存在潜在的共性。在这里，我们专注于两种细胞事件，即胞质[Ca2+]cyt 水平的增加和胞质酸化，如何作为参与调节植物细胞中发育和刺激诱导的 PCD 的早期信号。
