Shoot meristems are maintained by pluripotent stem cells that are controlled by CLAVATA-WUSCHEL feedback signaling. This pathway, which coordinates stem cell proliferation with differentiation, was first identified in Arabidopsis, but appears to be conserved in diverse higher plant species. In this Review, we highlight the commonalities and differences between CLAVATA-WUSCHEL pathways in different species, with an emphasis on Arabidopsis, maize, rice and tomato. We focus on stem cell control in shoot meristems, but also briefly discuss the role of these signaling components in root meristems.
茎尖分生组织由多能干细胞维持，这些干细胞受CLAVATA-WUSCHEL反馈信号调控。这条协调干细胞增殖与分化的信号通路最初在拟南芥中被发现，但在多种高等植物物种中似乎是保守的。在本综述中，我们着重介绍不同物种中CLAVATA-WUSCHEL信号通路的异同，重点关注拟南芥、玉米、水稻和番茄。我们聚焦于茎尖分生组织中的干细胞调控，但也简要讨论了这些信号成分在根尖分生组织中的作用。
