Appears in the following schemes

FLC regulation through protein complexes

Protein function

Encodes a zinc finger protein involved in the regulation of FLC expression.

Phenotype

Overexpressor:
FES1 overexpressor does not display any flowering-time phenotype. [Schmitz et al., 2005]

Single mutant:
fes1 single mutant is early flowering under both SD and LD conditions in the Col FRI background. ( The flowering-time phenotype of the single mutant is only visible in the Col FRI background.) [Schmitz et al., 2005]

Remarks:
FES1 is involved in the upregulation of FLC expression and its mutation leads to the complete suppression of FRI-mediated delayed flowering. [Schmitz et al., 2005]

Function:
Transcriptional activator involved in the FRIGIDA-mediated vernalization pathway, but not in the autonomous flowering pathway. Acts cooperatively with FRI (FRIGIDA) or FRL1 (FRIGIDA-LIKE 1) to promote FLC (FLOWERING LOCUS C) expression. Required for the stabilization of the FRI-C complex. [Data from UniProt]
