RT the expression of FT-like genes under SD conditions in rice.";
RL Planta 228:355-365(2008).
CC -!- FUNCTION: Probable transcription factor involved in the regulation of
CC flowering time under short day (SD) conditions. Functions as repressor
CC of flowering under SD conditions, independently of HD1, EHD1, MADS50
CC and MADS51. Controls flowering time under SD conditions by negatively
CC regulating the expression of HD3A and FTL.
CC {ECO:0000269|PubMed:18449564}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00357}.
CC -!- INDUCTION: Circadian-regulation under long day (LD) conditions.
CC Expression increases after the beginning of the dark period, peaks at
CC dawn, stays high four hours and gradually decreases until sunset.
CC {ECO:0000269|PubMed:18449564}.
CC -!- MISCELLANEOUS: Plants over-expressing CO3 display late flowering under
CC short day (SD) conditions. {ECO:0000269|PubMed:18449564}.
CC -!- SIMILARITY: Belongs to the CONSTANS family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAD36814.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
