摘　　要：在植物赤霉素合成途径中,GA3ox将无活性的GA12和GA53转变为有活性的GA4和GA1,进而实现了调控植物生长发育。GA生物合成及其信号传导途径相关基因的研究备受关注。本研究对高等植物体内GA3-oxidase基因的克隆、组织表达、调控表达、功能鉴定等方面的研究进行综述,并对进一步深入研究GA3ox的互作、抗逆性等方面进行了展望,揭示GA3-oxidase氧化酶信号网络系统及其作用机制。GA3ox regulates plant growth and development by transforming inactive GA12 and GA53 into active GA4 and GA1 in the gibberellin synthesis pathway.Research on GA biosynthesis and related genes in GA signal transduction pathway have been a hot topic.In this paper,the cloning,tissue expression,regulatory expression and functional identification of GA3-oxidase gene in higher plants were reviewed,and further studies on the interaction and stress resistance of GA3ox were prospected,so as to reveal the signal network system of GA3-oxidase and its mechanism.
