Encodes a protein required for FRIGIDA-mediated activation of FLC.
Remarks:flx single mutant has reduced FLC expression levels. [Lee et al., 2013][Andersson et al., 2008]Single mutant:flx single mutant is early flowering under both SD and LD conditions. [Lee et al., 2013][Andersson et al., 2008]Function:Transactivator required for FRIGIDA-mediated activation of FLC and for the expression of the repressors of flowering AGL27/MAF1 and AGL31/MAF2. Does not alter expression of known activators of FLC expression. Not required for the photoperiod response or for the vernalization response. Not redundant with FLXL4. [Data from UniProt]
