Progresses on Molecular Mechanisms of Flowering Transition in Arabidopsis

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.
