Acetylated chromatin Chromatin FLC FLD FLC 1Acetyl groups on histone proteins destabilize chromatin Transcription Transcription structure. Flowering locus C (FLC) encodes a regulator protein that represses flowering MRNA MRNAI Translation Translation Restoration 5.that removes acetyl of chromatin groups and restores chromatin structure. No transcription Regulator protein Deacetylase 6 No transcription of FC takes place. enzyme No flowering takes place. Flowering locus D (FLD) encodes a deacetylase enzyme.. Flowering is not suppressed, and so flowering takes place. Repression of flowering No repression of flowering 17.3 Flowering in Arabidopsis is controlled in part by FLD, a gene that encodes a deacetylase enzyme.
