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}.
CC   -!- TISSUE SPECIFICITY: Expressed in some of the meristems of arrest-stage
CC       cauliflower heads. {ECO:0000269|PubMed:9084216}.
CC   -!- DEVELOPMENTAL STAGE: Accumulates in floral primordia and is maintained
CC       at a maximal level at the floral bud stage of arrest.
CC       {ECO:0000269|PubMed:18332227}.
