CC   -!- FUNCTION: Controls floral meristem identity. Is also required for
CC       normal development of sepals and petals. Is required for the transition
CC       of an influorescence meristem into a floral meristem. Interacts with
CC       LEAFY (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00251}.
