摘要
拟南芥是分子和遗传学研究的模式植物,对植物花发育及控制花形态建成的分子遗传机制的研究进展主要是建立在对拟南芥研究的基础之上,拟南芥开花主要受到4个途径(自主途径、赤霉素途径、春化作用和光周期途径)的内源和外界信号的同时诱导.该文对近年来国内外有关拟南芥开花诱导的4个途径的分子机制研究进展进行综述,并初步绘制出各开花诱导途径基因间的调控网络图,以进一步明确基因间的相互作用模式及其在整个开花过程中的作用地位.
Arabidopsis is a model plant for studying of molecular genetics.The research on molecular genetic mechanisms of floral development and morphogenesis has made many progresses,and mainly came from Arabidopsis.The flowering transition of Arabidopsis is controlled by endogenous and environmental signals,mostly through four pathways：autonomous pathway,gibberellin pathway,vernalization pathway,and photoperiod pathway.The progresses in the study on Arabidopsis flowering transition are summarized,and the primary regulation network in different flowering pathways is drawn to provide the references for the future gene function and interaction researches.
