Abstract FLOWERING LOCUS T(FT)is a key material to control the changes from vegetative growth to reproductive development.And FT protein,as a long-range signal,plays an important role in regulating the flowering time.FT can express in leaves,which is regulated by some flowering pathways,such as photoperiod way.It is FT protein not FT mRNA that is transported into the apex meristem for flowering induction.This paper summarizes the mechanisms for FT gene expression regulation,FT protein long-range transportation and flowering induction in apex meristem.It also discusses about the prospects of future research works,according to present research status.
