| Outline of Final Research Achievements |
In higher plants, florigen is a mobile hormone that determines the flowering time, but its regulatory mechanism for floral induction remains unclear. In this study, we focused on anti-florigen, which suppresses floral induction antagonizing with florigen, to clarify the regulatory role in flowering. From the structural and biochemical analysis, anti-florigen was found to form a stable complex with florigen receptor on target receptor and inhibited a formation of florigen-receptor complex. The complex formation of florigen and anti-florigen against to the receptor is exchangeable, suggesting that the balance of the two complexes are important for floral induction.
