Appears in the following schemes

FLC regulation through protein complexes

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. [Data from UniProt]
