摘要
乙烯为植物重要内源激素,参与植物多项生命活动,在花发育及衰老进程中起重要调节作用。在花卉中,研究者可通过调控其乙烯生物合成及信号转导途径相关基因影响内源乙烯生成,继而影响其发育与衰老进程。目前,通过调控内源乙烯延长花期的研究主要应用于观赏花卉,对于药用等其他花类应用尚少。对乙烯生物合成和信号转导途径模型及其相关基因的互作模式、近年来乙烯反应中介导花发育与衰老相关基因克隆及调控的相关研究进行综述,以期将通过调控内源乙烯途径相关基因来延缓植物花期的研究应用于其他花期短的观赏切花、花类药材等,为从基因水平调控内源乙烯以获得花期延长的观赏、药用花类等优良育种提供参考。
Ethylene,a key endogenous phytohormone,is involved in multiple plants’life activities,and plays an important role in regulating floral development and senescence.In flowers,researchers can affect the production of ethylene by regulating related genes of ethylene biosynthesis and its signal transduction,and further regulate the floral development process and aging process.Currently,studies on prolonging florescence by regulating endogenous ethylene are mainly applied to ornamental flowers,but few to medicinal or other flowers.This paper summarizes the models of ethylene biosynthesis and ethylene signal transduction pathway,interaction patterns of its related genes,and researches of cloning and regulating related genes involved in ethylene response mediating floral development and senescence in recent years.It is expected to apply studies which prolong plants’florescence by regulating related genes of ethylene biosynthesis and signal transduction pathway to ornamental,medicinal and other flowers with short flowering period,and provide references for cultivating fine breeding of ornamental and medicinal flowers by regulating endogenous ethylene generation and transduction at genetic level.
