Abstract：Flowering is an important trait of Brassica vegetables，there are 4 pathways to control flowering：vernalization pathway，photoperiod pathway，gibberellin pathway and autonomous path- way．Although these 4 pathways have different gene regulatory networks，at last gather-together to the same integrator eventually．This paper refers to Arabidopsis thaliana L. to review the molecular mechanisms of key gene FLC in vernalization and autonomous pathways，CO in photoperiod pathway and gibberellin pathway in Brassica vegetables．It also analyzes the regulating functions of the key genes in flowering signal integrators and discusses about the prospects of future research works，according to the present research status．
