【摘要】 赤霉素是一种常见的植物激素,在高等植物的各个生长发育阶段都具有重要的调控作用.赤霉素与其他所有激素间都存在相互作用,其作用的方向和类型取决于组织器官、发育阶段以及环境条件,使赤霉素对植物生长发育的调控及其在不同器官中的生理功能不同.本文对近年来国内外关于赤霉素的信号传导、作用机制以及赤霉素与其他植物激素间的相互作用及其调控机理的研究进行综述,以探讨赤霉素信号应答的复杂网络体系.更多还原

【Abstract】 Gibberellin is a common plant hormone which plays an important role in the growth and development stage in higher plants.GA has many interactions with all other hormones,and the effection and type of its action depends on the tissues and organizations,developmental stages and environmental conditions.Theresore,GA plays different roles in regulating plant growth and development and has different physiological functions in different organs.In this paper,research on the GA signal transduction,action mechanisms,as well as interactions with other hormones and its regulation mechanism both at home and abroad in recent years are reviewed,in order to explore the complex GA signal response network system.更多还原
