高等植物赤霉素生物合成关键组分 GA20-oxidase 氧化酶基因的研究进展
Studies on the Gene of Key Component GA20-oxidase for Gibberellin Biosynthesis in Plant
摘要
Abstract
GA20-oxidase,as a key synthetizing and regulating enzyme in the biosynthesis of gibberellic acid,directly regulates the generation of biological GAs. It is also a multifunctional enzyme,and its most important feature is negative feedback regulation. GA20-oxidase plays an important regulating role in the development and physiological processes of plants. This article summarizes the recent studies on the molecular cloning and regulating expression analysis of GA20-oxidase genes and their effects on plant height,fiber formation,flowering,yield traits,etc.,and explains the interactions of GA20-oxidase gene with hormones,photoperiod,stress resistance and other factors,aiming at revealing the signal network system and its mechanism of GA20-oxidase.关键词
