| Outline of Final Research Achievements |
Florigen is a mobile plant hormone that determines the flowering time in higher plants, but its regulatory mechanism remains unclear. In this study, we focused on an anti-florigen, which suppresses flowering antagonizing with florigen, to clarify the role in floral regulation. From structural and biochemical analysis, anti-florigen was found to form a stable complex with florigen receptor and inhibit formation of florigen-receptor complex. The bindings of florigen and anti-florigen to receptor were exchangeable, suggesting that the balance of the two proteins is important for determining floral transition.
