摘要
高等植物从营养生长过渡到生殖生长,是由外界环境条件及自身因子相互作用的结果。植物成花本质上是由花发育调控基因控制的,了解植物花发育调控基因功能后,可以人为地控制植物成花。花发育调控基因有个重要的特点是,其功能在不同植物间是相对保守的,可以广泛应用于转基因的研究中。现综述了植物花发育过程,拟南芥主要的花发育调控基因,系统介绍花发育调控基因在提高经济作物生物产量、植物雄性不育、缩短童期、观赏植物分子育种方面的应用。
The transition from vegetative to reproductive phases during higher plants development was the result of a complex interaction of environmental and endogenous factors.Essentially flowering was control by flowering regulation genes,after understanding the function of them,we can artificially control the flowering of plants.The flowering regulating genes,whose function were conserved among different plants,were widely used in the research of transgenic.This paper reviewed the research on the process of flowering and the main flowering regulating genes in Arabidopsis thaliana,its application on improving biomass of economic crops,making plant male sterility,reducing juvenile phase,molecular breeding of ornament plants were systematically introduced.
