Stomata are pores on plant epidermis that facilitate gas exchange and water evaporation between plants and the environment. Given the central role of stomata in photosynthesis and water-use efficiency, two vital events for plant growth, stomatal development is tightly controlled by a diverse range of signals. A family of peptide hormones regulates stomatal patterning and differentiation. In addition, plant hormones as well as numerous environmental cues influence the decision of whether to make stomata or not in distinct and complex manners. In this review, we summarize recent findings that reveal the mechanism of these three groups of signals in controlling stomatal formation, and discuss how these signals are integrated into the core stomatal development pathway.
气孔是植物表皮上的孔，促进植物与环境之间的气体交换和水分蒸发。鉴于气孔在光合作用和水分利用效率（植物生长的两个重要事件）中的核心作用，气孔的发育受到多种信号的严格控制。一类肽激素调节气孔的模式和分化。此外，植物激素以及许多环境线索以独特而复杂的方式影响着是否形成气孔的决定。在这篇综述中，我们总结了最近的发现，揭示了这三组信号控制气孔形成的机制，并讨论了这些信号如何整合到核心气孔发育途径中。
