Mean coexpression and mean functional similarity of gene pairs in coacetylation domains. (A) Mean coexpression of gene pairs in co-ΔH3K14ac domains (black) and in co-ΔH4ac domains (red), immediate neighboring gene pairs (blue) and 10,000 random cis-pairs (green). The left-hand side is coexpression in H2O2-stress condition, and the right-hand side is the mean coexpression of data sets from 23 different references. (B) Mean semantic similarity (SIM) in Gene Ontology. (C) and (D) Mean coexpression and mean SIM of gene pairs by excluding the divergent pairs and pairs with the same TFBS.
