CC   -!- FUNCTION: Transcription factor that promotes early floral meristem
CC       identity in synergy with LEAFY. Displays a redundant function with
CC       CAULIFLOWER in the up-regulation of LEAFY. Required subsequently for
CC       the transition of an inflorescence meristem into a floral meristem, and
CC       for the normal development of sepals and petals in flowers. Regulates
CC       positively B class homeotic proteins (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homodimer capable of binding to CArG-box sequences.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00251}.
