RX PubMed=18332227; DOI=10.1093/jxb/erm327; RA Duclos D.V., Bjoerkman T.; RT "Meristem identity gene expression during curd proliferation and RT flower initiation in Brassica oleracea."; RL J. Exp. Bot. 59:421-433(2008). CC -!- FUNCTION: Probable transcription factor that promotes early floral CC meristem identity in synergy with APETALA1, FRUITFULL and LEAFY. CC Is required subsequently for the transition of an inflorescence CC meristem into a floral meristem. Seems to be partially redundant CC to the function of APETALA1 (By similarity). CC -!- SUBUNIT: Homodimer capable of binding to CArG-box sequences (By CC similarity). CC -!- SUBCELLULAR LOCATION: Nucleus (By similarity). CC -!- TISSUE SPECIFICITY: Expressed in some of the meristems of arrest- CC stage broccoli heads. CC -!- DEVELOPMENTAL STAGE: Accumulates in early floral primordia and CC fade out in cells that will give rise to stamens and carpels. CC -!- MISCELLANEOUS: CAULIFLOWER that may contribute to shape of the CC floral meristem. This trait has likely been selected by early CC farmers during the domestication of modified inflorescence CC structures. CC -!- SIMILARITY: Contains 1 K-box domain. CC -!- SIMILARITY: Contains 1 MADS-box domain.
