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