植物赤霉素氧化酶及其功能研究进展
Research Progress in Plant Gibberellin Oxidase and Its Functions
摘要
Abstract
Gibberellin(GA)is an important plant hormone that regulates plant development and its response to environmental signals,the biosynthesis and metabolism of GA are involved in a variety of enzymes,and gibberellin oxidase plays a key role in regulating the biosynthesis of gibberellin.Gibberellin oxidase is the key enzyme in gibberellin biosynthesis and catabolism and plays a complex regulatory role in the gibberellin biosynthetic pathway in plants.GA20ox(gibberellin 20 oxidase),GA3ox(gibberellin 3 oxidase)and GA2ox(gibberellin 2 oxidase)are the gibberellin oxidase gene family.GA20ox and GA3ox are rate-limiting enzymes in gibberellin biosynthesis,while GA2ox is the key enzyme in gibberellin catabolism.And they regulate GA biosynthesis pathway in plants and ensure the plant's demand for GA during growth and development and interaction with the environment.Gibberellin oxidase is involved in regulating plant growth and development,and it is strictly regulated by environment and endogenous factors.Gibberellin oxidase has been cloned in Arabidopsis thaliana,Oryza sativa;and poplar species,and its function varies among species.Therefore,this review focuses on the functions of GA20ox,GA3ox and GA2ox,describes the characteristics,spatial and temporal expression of plant gibberellin oxidase and the response of gibberellin oxidase to light and hormones,with special emphasis on the function of gibberellin oxidase and its research progress,aiming to provide information for further studies on gibberellin oxidase gene function.关键词
