H3K9ac signal strength of three subsets of the clustered core promoters with (A) lowly, (B) medium and (C) highly expressed promoters. The H3K9ac signal of the upstream cluster shows dramatic increase when comparing the lowly and medium expressed promoters with the highly expressed promoters. The downstream cluster shows little change in the same comparison.
