MADS-box transcription factor that acts with AGL42 and AGL72 in the control of flowering time. Promotes flowering at the shoot apical and axillary meristems. Seems to act through a gibberellin-dependent pathway. Interacts genetically with SOC1 and its expression is directly regulated by SOC1. A number of isoforms are produced. According to EST sequences. Expressed in the shoot apical meristem (SAM) during the vegetative phase and the floral transition. After floral transition, expressed in apical meristem (AM), inflorescence meristem (IM) and floral primordia. No visible phenotype under normal growth conditions.
