CC   -!- FUNCTION: Probable transcription factor that promotes early floral
CC       meristem identity in synergy with APETALA1, FRUITFULL and LEAFY. Is
CC       required subsequently for the transition of an inflorescence meristem
CC       into a floral meristem. Seems to be partially redundant to the function
CC       of APETALA1 (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}.
CC   -!- MISCELLANEOUS: CAULIFLOWER may contribute to the shape of the floral
CC       meristem. This trait has likely been selected by early farmers during
CC       the domestication of modified inflorescence structures.
