Protein function
Encodes a DNA-binding protein involved in the repression of
FLC expression.
Phenotype
Overexpressor: VRN1 overexpressor is early flowering under both SD and LD conditions in the
vrn1;
fca double mutant background.
[Levy et al., 2002] Single mutant: vrn1 single mutant does not display any flowering-time phenotype.
[Levy et al., 2002] Remarks: VRN1 is required for the deposition of repressive H3K9 methylation marks at the
FLC locus.
[Mylne et al., 2006][Levy et al., 2002] Function:Involved in the regulation of vernalization. Acts as transcriptional repressor of FLC, a major target of the vernalization pathway. Binds DNA in vitro in a non-sequence-specific manner.
