Research Abstract |
In this study, we showed that the major component of florigen is FT protein (not mRNA as previously reported). Amino acid residues essential for long-distance transport and action of FT protein to promote flowering were identified. This will enable us to elucidate the mechanism and machinery of FT transport. We also demonstrated phosphorylation of the C-terminal region of FD, an FT partner bZIP transcription factor, which is required for the FT/14-3-3/FD complex formation. A novel role of florigen in regulation of axillary shoot development and elongation was elucidated. We showed that BRC1 acts as a regulator of florigen activity in axillary buds.
