Protein function
Encodes a transcription factor which is part of the DREB subfamily A-1 of ERF/AP2 transcription factor family.
Phenotype
Overexpressor: CBF1 overexpressor displays pleiotropic defects, including late flowering under LD conditions.
[Gilmour et al., 2004] Multiple mutant: The downregulation of both
CBF1 and
CBF3 through antisense constructs leads to a reduction of freezing tolerance.
[Novillo et al., 2007] Remarks: The late-flowering phenotype of
CBF1 overexpressor is suppressed by GA application.
[Achard et al., 2008] Function:Transcriptional activator that binds specifically to the DNA sequence 5 -[AG]CCGAC-3 . Binding to the C-repeat/DRE element mediates cold-inducible transcription. CBF/DREB1 factors play a key role in freezing tolerance and cold acclimation.
