在高等植物中，茎器官如叶、枝和花是由茎尖分生组织（SAM）产生的，SAM是位于茎尖的一小群未分化细胞。 SAM 保持其多能性，同时在其外围产生侧向器官。 SAM 在胚胎发生过程中出现，其定位需要轴依赖性胚胎模式和胚胎顶端的区室化。在这里，我们介绍了拟南芥这些过程中涉及的主要因素，并讨论了胚胎 SAM 的建立过程。
In higher plants, shoot organs such as leaves, branches, and flowers are generated from the shoot apical meristem (SAM), a small group of undifferentiated cells located at the tip of the shoot. The SAM maintains its pluripotency and simultaneously produces lateral organs at its periphery. The SAM arises during embryogenesis and its positioning requires axis-dependent embryo patterning and compartmentalization of the embryo apex. Here, we introduce major factors involved in these processes inArabidopsis thalianaand discuss how the embryonic SAM is established.
