NCBI Protein Information
protein FLOWERING locus D-like protein
NCBI Summary
Encodes a plant homolog of a SWIRM domain containing protein found in histone deacetylase complexes in mammals. Lesions in FLD result in hyperacetylation of histones in FLC chromatin, up-regulation of FLC expression and extremely delayed flowering. FLD plays a key role in regulating the reproductive competence of the shoot and results in different developmental phase transitions in Arabidopsis.

UniProt Comments
Probable histone demethylase that promotes flowering independently of the photoperiod and vernalization pathways by repressing FLOWERING LOCUS C (FLC), a floral repressor that blocks the transition from vegetative to reproductive development. Probably mediates histone H3 'Lys-4' demethylation at FLC locus. Seems to act in partial redundancy with LDL1 and LDL2 to repress FLC expression. Required for histone H4 deacetylation of FLC locus. May be a component of the histone deacetylase complex.
