Correlation of 4acC with gene expression. a Venn diagram showing the overlaps between expressed genes and 4acC-marked genes. An expressed gene was defined by having an FPKM > 0. FPKM stands for the fragments per kilobase of exon per million fragments mapped from RNA-seq data. The p values were calculated by Fisher’s exact test. b Distributions of 4acC peaks over protein-coding gene regions among groups of genes with high to low (top 25%, 25–50%, 50–75%, and 75–100% based on FPKM) expression levels. c Box plot of gene expression levels (based on FPKM values) for genes with or without 4acC peaks (4acC and non-4acC) as well as genes with 4acC peaks around the TSS (TSS) or away from the TSS (non-TSS). The p values were calculated for significant differences between two groups by the Mann–Whitney U test
