Shoot apical meristems are composed of proliferating, embryonic type cells, that generate tissues and organs throughout the life of the plant. This review covers the cell biology of the higher plant shoot apical meristem (SAM). The first section describes the molecular basis of plant cell growth and division. The genetic mechanisms, that operate in meristem function and the identification of several key regulators of meristem behavior are described in the second section, and intercellular communication and coordination of cellular behavior in the third part. Finally, we discuss some recent results that indicate interaction between the cellular regulators, such as the cell cycle control genes and developmental regulators.
茎尖分生组织由不断增殖的胚胎型细胞组成，这些细胞在植物的整个生命周期中产生组织和器官。本综述涵盖了高等植物茎尖分生组织（SAM）的细胞生物学。第一部分描述了植物细胞生长和分裂的分子基础。第二部分阐述了在分生组织功能中起作用的遗传机制以及分生组织行为的几个关键调节因子的鉴定，第三部分介绍了细胞间通讯和细胞行为的协调。最后，我们讨论了一些最近的结果，这些结果表明细胞调节因子之间的相互作用，如细胞周期控制基因和发育调节因子。
