Stomata are specialized epidermal structures that control the exchange of water and carbon dioxide between the plant and the atmosphere. The classical developmental mechanisms that define cell fate and tissue patterning - cell lineage, cell-cell interactions and signals from a distance - are employed to make stomata and to define their density and distribution within the epidermis. Recent work has shown that two genes that are involved in stomatal pattern may encode components of a classical cell-surface-receptor-mediated signaling cascade. Additional work has suggested that signals from the overlying cuticle and the underlying mesophyll also influence stomatal pattern. These findings highlight the need for models that explain how the signals that regulate stomatal development are integrated and how they act to regulate cell polarity, the cell cycle and, ultimately, cell fate.

在气孔发育中整合信号。

气孔是专门的表皮结构，可控制植物与大气之间的水和二氧化碳交换。定义细胞命运和组织模式的经典发育机制-细胞谱系，细胞间的相互作用和远处的信号-被用于制作气孔并定义其在表皮内的密度和分布。最近的工作表明，气孔模式中涉及的两个基因可能编码经典的细胞表面受体介导的信号级联的成分。额外的工作表明，来自上皮表皮和下层叶肉的信号也会影响气孔模式。这些发现凸显出需要模型来解释调节气孔发育的信号如何整合以及它们如何调节细胞极性，
