FLC is the key repressor of flowering in the process ofvernalization. Methylation of Lysine 9 of histone H3 (H3K9me) is achromatin modification associated with heterochromatin. Methylationof Lysine 4 of histone H3 (H3K4me) is a chromatin modificationassociated with euchromatin. Which proteins do you expect to beactive on the FLC gene at specific times of year?
