摘要
气孔是陆生植物表皮上可以调节的小孔,也是植物进行气体交换的主要通道。气孔不仅对植物的光合作用起着非常关键的作用,而且对全球的碳循环和水循环具有重要的影响。气孔分布和形态结构在单、双子叶植物间也有较大的差异,这些差异因植物种类不同影响着气孔发育的精细调控。本文综述了调控气孔前体细胞命运的分子网络、细胞极性分裂和表观遗传机制,归纳了外界环境信号通过与内源信号通路互作介导气孔发育的过程,提出了气孔发育基于多水平控制的气孔发育模型。
Stomata are small adjustable pores on the surface（epidermis） of land plants that act as a main conduit for gas exchange. They not only play an essential role in photosynthesis of green plants but also exert an important influence on the global carbon and water cycle. There are great differences between monocots and dicots in distribution and morphological structure of the stomata, affecting the species-specific regulation of stomatal development. In this review, we summarize the molecular regulation networks associated with stomatal precursor cell fate determination and the epigenetic mechanisms on regulation of polar cell division. We also outline the stomatal development processes mediated by crosstalk between exogenous and intrinsic signals, and propose a model of multilevel regulation of stomatal development.
