Cloning and function research of FT (flowering locus T)-like homologs in cotton havent been reported.In the present study, an FT-Like homolog was isolated from Gossypium hirsutum L.through RT-PCR and RACE, which was designated GhFTL1 gene.The entire coding region is 525 bp and encoded a polypeptide of 174 amino acids with 75% homology to AtFT and 84% to Hd3a, respectively.GhFTL1 protein contains two critical residues tyrosine (Tyr) and glutamine (Gln), which identified as diagnostic of true FT family proteins.Phylogenetic analysis and 3-dimensional structure indicated GhFTL1 gene belongs to FT-like homologs.
