在维管植物中，气孔平衡着两种相反的功能：打开气孔促进二氧化碳吸收，关闭气孔防止水分过多流失。在这里，我们讨论了三种已知的控制被子植物气孔运动的信号通路的进化，以响应光、二氧化碳和脱落酸（ABA）。我们研究了参与这些途径的关键信号基因的进化起源，并比较了它们在被子植物和苔藓之间的表达模式。我们认为，植物类群间气孔对刺激敏感性的差异源于：(i)基因的存在/缺失，（ii）基因空间表达模式的特异性，以及（iii）蛋白质特征和功能相互作用的差异。
In vascular plants, stomata balance two opposing functions: they open to facilitate CO2uptake and close to prevent excessive water loss. Here, we discuss the evolution of three major signalling pathways that are known to control stomatal movements in angiosperms in response to light, CO2, and abscisic acid (ABA). We examine the evolutionary origins of key signalling genes involved in these pathways, and compare their expression patterns between an angiosperm and moss. We propose that variation in stomatal sensitivity to stimuli between plant groups are rooted in differences in: (i) gene presence/absence, (ii) specificity of gene spatial expression pattern, and (iii) protein characteristics and functional interactions.
