气孔是植物枝条表面可调节的气孔，用于有效的气体交换和水分控制。气孔的存在对植物的生长和生存至关重要，气孔的进化被认为是陆地植物的一项关键的发展创新，使大约4.5亿年前的水生环境得以在陆地上定居。在过去的二十年里，利用模式植物拟南芥进行的分子遗传学研究发现了调控气孔发育的关键基因和信号模块：主要的调控转录因子协调细胞状态转换和多肽-受体信号转导途径，共同促进表皮内气孔的适当模式。从苔藓到被子植物的不同植物物种的研究，已经开始揭示气孔发育中核心模块的保守性和独特性。在这里，我回顾了在表皮组织模式的背景下气孔发育的机制。首先，我介绍了模式植物拟南芥的气孔模式和分化的核心调控机制。随后提出的实验证据支持这一观点，即叶表皮中的不同类型的细胞，即气孔、水生毛孔、铺面细胞和毛状体，要么具有共同的发育起源，要么在发育过程中相互影响彼此的基因调控电路。重点是调节气孔和表皮细胞之间平衡的外在和内在信号，特别是通过控制气孔-谱系地面细胞(SLGC)的命运保持在气孔细胞谱系中或分化为表皮细胞。最后，讨论了表皮和下层叶肉/维管组织之间的组织间通讯对气孔分化的影响。了解气孔前体细胞的动态行为及其在组织和器官发育的更广泛背景下的分化，可能有助于在特定农业应用和不断变化的环境中为最佳生长和生产力量身定做植物。
Stomata are adjustable pores on the surface of plant shoots for efficient gas exchange and water control. The presence of stomata is essential for plant growth and survival, and the evolution of stomata is considered as a key developmental innovation of the land plants, allowing colonization on land from aquatic environments some 450 million years ago. In the past two decades, molecular genetic studies using the model plant Arabidopsis thaliana identified key genes and signalling modules that regulate stomatal development: master regulatory transcription factors that orchestrate cell state transitions and peptide–receptor signal transduction pathways, which, together, enforce proper patterning of stomata within the epidermis. Studies in diverse plant species, ranging from bryophytes to angiosperm grasses, have begun to unravel the conservation and uniqueness of the core modules in stomatal development. Here, I review the mechanisms of stomatal development in the context of epidermal tissue patterning. First, I introduce the core regulatory mechanisms of stomatal patterning and differentiation in the model species A. thaliana. Subsequently, experimental evidence is presented supporting the idea that different cell types within the leaf epidermis, namely stomata, hydathodes pores, pavement cells and trichomes, either share developmental origins or mutually influence each other’s gene regulatory circuits during development. Emphasis is placed on extrinsic and intrinsic signals regulating the balance between stomata and pavement cells, specifically by controlling the fate of stomatal-lineage ground cells (SLGCs) to remain within the stomatal cell lineage or differentiate into pavement cells. Finally, I discuss the influence of intertissue layer communication between the epidermis and underlying mesophyll/vascular tissues on stomatal differentiation. Understanding the dynamic behaviours of stomatal precursor cells and their differentiation in the broader context of tissue and organ development may help design plants tailored for optimal growth and productivity in specific agricultural applications and a changing environment.
