Protein function
Encodes transcription factor involved in photomorphogenesis and gibberellin biosynthesis.
Phenotype
Overexpressor: ATH1 overexpressor is late flowering under both SD and LD conditions. (Results obtained in the col-8 background.)
[Proveniers et al., 2007] Remarks: ath1 single mutant has reduced
FLC expression levels and
ATH1 overexpressor has increased
FLC expression levels.
[Proveniers et al., 2007] Single mutant: ath1 single mutant is early flowering under SD conditions, but only in the Col-8 background.
[Proveniers et al., 2007] Function:Transcription factor which may be involved in the signal transduction pathway downstream of the COP1 gene. Controls floral competency as a specific activator of FLC expression. Is responsive of the nuclear import of SHOOT MERISTEMLESS (STM).
