Stomata constantly open and close to optimize gas exchange. While the genetic programme guiding early development is well described, the formation of functional guard cells remains enigmatic. This review highlights recent findings on the developmental and morphogenetic processes shaping this essential and morphologically diverse cell type in Arabidopsis and grasses.

为运动而生的形态学：形成多样的气孔保卫细胞

气孔不断打开和关闭以优化气体交换。虽然指导早期发育的遗传程序得到了很好的描述，但功能性保卫细胞的形成仍然是个谜。本综述重点介绍了在拟南芥 和禾本科植物中形成这种基本且形态多样的细胞类型的发育和形态发生过程的最新发现 。
