Outline of Final Research Achievements

Although molecular identity of florigen as FT protein was firmly established, many aspects of florigen still remain elusive. With this in mind, we studied temporal aspect of florigen transport and amino acid residues of FT protein specifically involved in its transport, spatial distribution and dynamics of FT protein in shoot apical meristem, and some factors involved in florigen production, complex formation and function. Main achievement includes elucidation of temporal aspect of florigen (FT protein) transport, identification of 3 specific amino acid residues involved in FT transport, discovery of transient accumulation of FT protein in shoot apical meristem before and during floral transition, and elucidation of a regulatory pathway of flowering by heavy-metal binding protein NaKR1 and potassium through transcriptional regulation of FT via miR156-SPL module.
