Protein function

Encodes a zinc finger transcription factor involved in the regulation of FT expression.

Phenotype

Overexpressor:
CO overexpressor is early flowering under both SD and LD conditions [Simon et al., 1996][Samach et al., 2000][Suü¾Œ–”¼rez-Lü¾Œ¶˜¼pez et al., 2001][Onouchi et al., 2000]

Single mutant:
co single mutant is late flowering under LD conditions only. [Simon et al., 1996][Koornneef et al., 1991][Samach et al., 2000][Putterill et al., 1995]

Function:
Putative transcription factor that acts in the long day flowering pathway and may mediate between the circadian clock and the control of flowering. Plays a role in the regulation of flowering time by acting on SUPPRESSOR OF OVEREXPRESSION OF CO1 , TERMINAL FLOWER 1 and FLOWERING LOCUS T . Also regulates P5CS2 and ACS10 (involved in proline and ethylene biosynthesis, respectively). [Data from UniProt]
