Modulates the competence to flowering of apical meristems. Involved in a GA-dependent response in apical meristems during the transition to flowering. After the photoperiodic induction of flowering and in early transition stages, expression is only detectable in the peripheral zone of apical meristems. Later on, it can also be found in floral meristems and in axillary meristems that form secondary inflorescences. Overexpression of FPF1 results in shortening of the time to flowering. Belongs to the FPF1 family.
