保卫细胞在植物中形成表皮气孔气体交换阀，并响应叶片中二氧化碳（CO2）浓度的变化来调节气孔的孔径。此外，气孔的发展受到不同植物物种中CO2浓度升高的抑制。有证据表明，植物可以通过保卫细胞和叶肉组织来感受CO2浓度的变化，从而介导气孔运动。本文综述了CO2调节植物气孔运动和CO2调节气孔发育的机制，以及CO2调节植物气孔导度和气体交换的机制。鉴于有必要选择和开发在气候变化中表现更好的作物品种，这一领域的研究是及时的。
Guard cells form epidermal stomatal gas exchange valves in plants and regulate the aperture of stomatal pores in response to changes in the carbon dioxide (CO2) concentration in leaves. Moreover, the development of stomata is repressed by elevated CO2 in diverse plant species. Evidence suggests that plants can sense CO2 concentration changes via guard cells and via mesophyll tissues in mediating stomatal movements. We review new discoveries and open questions on mechanisms mediating CO2-regulated stomatal movements and CO2 modulation of stomatal development, which together function in CO2-regulation of stomatal conductance and gas exchange in plants. Research in this area is timely in light of the necessity of selecting and developing crop cultivars which perform better in a shifting climate.
