FLOWERING LOCUS C (FLC) is a major regulator of flowering time in Arabidopsis. Repression of FLC occurs in response to prolonged cold exposure (vernalization) and is associated with an enrichment of the repressive histone modification trimethylated H3 lysine 27 (H3K27me3) and a depletion of the active histone modification H3K4me3 at FLC chromatin. In two cases genes adjacent to FLC are also repressed by vernalization. NEOMYCIN PHOSPHOTRANSFERASE II (NPTII) adjacent to an FLC transgene is… CONTINUE READING
