| 摘 要： | 气孔保卫细胞是单个细胞水平研究ABA信号转导机制的一个模式系统。脱落酸(ABA)通过对保卫细胞生理生化状态、胞质Ca^2 浓度及其离子通道调节诱导气孔关闭过程。这个过程涉及的因素有：ROS、IP3、cADPR、蛋白质的可逆磷酸化等。

| Abstract: | Guard cells surround stoma in the epidermis of plant leaves and stems. Stomatal guard cells have become a highly developed model system for characterizing early signal transduction mechanism in plants.Abscisic acid(ABA) can induce stomatal closure effectively through regulating the physiological and biochemical state of the guard cells. ABA regulated ion channels are key factors of ABA_induced stomatal closure. During the process,many factors are involved,including ROS, IP 3, cADPR,protion phosphorylation and dephosphorylation etc. |
