Protein function
Encodes a protein required for
FRIGIDA-mediated activation of
FLC.
Phenotype
Remarks: flx4 mutation has only very little or no effect on the flowering time of the Col-0 background.
[Ding et al., 2013][Lee et al., 2013] Single mutant: flx4 mutation supresses the late-flowering phenotype of non-vernalized Col
FRI plants.
[Ding et al., 2013][Lee et al., 2013] Remarks: flx single mutant has reduced
FLC expression levels.
[Lee et al., 2013] Function:Involved in FLC activation and flowering time control, but has no transcriptional activation activity. Probably part of the FRI-C complex, but is not redundant with FLX.
