Functional genomic landscape of major VG clusters in the venom gland. (A–C) VG clusters with gene expression indicated by color (brighter colors are more highly expressed) and inferred interactions with putative venom enhancer regions (vPERs). For the H3K27ac ChIP-seq, H3K4me3 ChIP-seq, and ATAC-seq layers, normalized read density is shown, and peaks are highlighted by black bars at the top of each plot. Super-enhancers (SEs) are denoted by yellow bars if present. Replicated ATAC-seq data are shown at bottom.
