Abstract: Using homolog cloning，this paper identified the FT homolog in cucumber and explored the
functions of CsFT through expression analyses，phylogenetic characterization and ectopic transformation
in Arabidopsis. Distinct from previous studies，CsFT is highly expressed in male and female flowers，
whereas almost undetectable in the leaves. Overexpression of CsFT in Arabidopsis results in early
flowering and terminal flowers at top of shoots，indicating that CsFT may play conserved role during
flowering as that in Arabidopsis.
