In Arabidopsis thaliana, the initiation of flowering is carried out by four genetic pathways: gibberellin, autonomous, vernalization, and light-dependent pathways. These processes are integrated by the function of the genes FD, FE, FWA, PDF2, SOC1, and FT at the integration pathway. The integrated signal of the floral induction is transmitted to the floral meristem identity genes LFY and AP1, and floral morphogenesis is performed.
