Identifying the landscape of chromatin accessibility via ATAC-seq in pigs. a Hierarchical clustering of samples using ATAC-seq signal intensity. b Distribution of the peak number and genome coverage in each tissue. c Venn plot showing the overlap of peaks identified in this study with those reported in Kern et al. [26]. d Pearson correlation heatmaps of 20 tissues by density of ATAC-seq distal peaks (left) and ATAC-seq proximal peaks (right). e Pie chart represents the proportion of peaks located in introns, intergenic, 5′UTR, 3′UTR and CDS regions
