Protein function

Encodes a component of the plant homeodomain-polycomb repressive complex 2 (PHD-PRC2).

Phenotype

Remarks:
maf5 mutation supresses the late-flowering phenotype of the vil2 single mutant, suggesting that VIL2 regulates flowering time through MAF5. [Kim et al., 2010]

Overexpressor:
VIL2 overexpressor does not display any flowering-time phenotype. [Kim et al., 2010]

Single mutant:
vil2 single mutant is late flowering under SD conditions only. [Kim et al., 2010][Kim et al., 2010]

Remarks:
VIL2 is necessary for the enrichment in H3K9me2 repressing marks at MAF5 locus. [Kim et al., 2010][Kim et al., 2010]

Function:
Maybe involved in both the vernalization and photoperiod pathways by regulating gene expression. Binds preferentially to dimethylated histone H3 Lys-9 (H3K9me2). Promotes flowering in non-inductive photoperiods (e.g. short days) through the maintenance of the epigenetically repressed state of MAF5 via H3K9me2 and plant homeodomain / polycomb repressive complex 2 (PHD-PRC2)-dependent H3K27me3.
