Stomata have significantly diversified in nature since their first appearance around 400 million years ago. The diversification suggests the active reprogramming of molecular machineries of stomatal development during evolution. This review focuses on recent progress that sheds light on how this rewiring occurred in different organisms. Three specific aspects are discussed in this review: (i) the evolution of the transcriptional complex that governs stomatal state transitions; (ii) the evolution of receptor-ligand pairs that mediate extrinsic signaling; and (iii) the loss of stomatal development genes in an astomatous angiosperm.
自气孔大约在4亿年前首次出现以来，其在自然界中已发生了显著的多样化。这种多样化表明在进化过程中气孔发育的分子机制发生了积极的重新编程。本综述重点关注了近期的研究进展，这些进展揭示了这种重新布线在不同生物体中是如何发生的。本综述讨论了三个具体方面：（i）控制气孔状态转变的转录复合体的进化；（ii）介导外在信号的受体-配体对的进化；以及（iii）一种无气孔被子植物中气孔发育基因的丧失。
