摘　　要：植物在生长过程中会遭受各种逆境胁迫,环境胁迫会引起植物体内一系列的信号反应,其中脱落酸(ABA)信号途径是一条重要的胁迫应答途径。作为ABA信号通路中的蛋白质激酶之一,气孔开放因子1(Stomatal opening factor 1,OST1)在植物逆境应答反应中扮演重要角色。因此,研究OST1基因在植物逆境应答中的功能有助于阐述植物耐逆分子机制。从OST1的相互作用因子及其在信号通路中的调控作用等方面进行阐述,对其介导的逆境应答机制进行了系统总结。Plants are subjected to all kinds of stresses in the process of growth. Environmental stresses can make plants to produce a series of signal transduction. Signal pathway of abscisic acid（ABA） is an important stress response pathway.Stomatal opening factor 1（OST1）, one of protein kinases in ABA signaling pathway, plays a pivotal role in plant. Studying the function of OST1 gene in plants will help to elaborate the molecular mechanisms of plant stress tolerance. Interacting factors of OST1 and its regulatory roles in the signal pathway were reviewed. The mechanisms of OST1 in stress response of plants were summarized.
