摘要
气孔是植物与外界环境进行气体与水分交换的重要通道,调节着植物的蒸腾与光合作用。在长期进化过程中,植物通过调节气孔行为和气孔发育机制来适应环境变化。不同植物气孔系的形成方式不尽相同,但过程均受到气孔发育信号网络系统的调节作用。近年来关于气孔发育机制的研究层出不穷,现重点综述各类转录因子、信号肽以及环境因子和植物激素对气孔发育的调节作用。该领域的研究为在微观层面揭示植物对环境变化的适应机制提供了科学基础。
Stomata play important roles in regulating gas and water exchange between plants and the environment, which determine transpiration and photosynthesis. In the process of evolution, land plants have adapted to environmental changes by regulating stomatal behavior and development. Stomatal patterning and development varies among diverse plant groups, while all the forming processes are mediated by series of signaling network. Studies on the mechanism underlying stomatal development have attracted wide academic attention in recent years. In this paper, we discuss how transcriptional factors, peptides, environmental cues and hormones affect stomatal development, so as to provide foundation of scientific research in revealing plant adaptive mechanisms to environmental changes at a molecular level.
