Figure Lengend Snippet: (A) Top, illustration of the part of the brain used for all experiments, labeled “non-visual brain”. Bottom, number of biological replicates of brains profiled using RNA-seq, Micro-C, ATAC-seq, or CUT&Tag for H3K4me3, H3K4me1, H3K27ac, H3K36me3, H3K9me3, H3K27me3, H2AK119ub, or for IgG control. (B) Micro-C contact maps for the whole-genome scale (left) and for portions of scaffold 15 ( Hsal 9.0) at increasing resolutions (res). The matrices are shown as KR-normalized, balanced contact frequencies. (C) Size in millions of base pairs for the longest 25 scaffolds (red colors) in comparison to all other scaffolds (white) in assembly version v1.0 , v8.6 , and v9.0 (this study). (D) Number of scaffolds in assembly version v1.0 , v8.6 , and v9.0 (current version). (E) ATAC, H3K27ac, H3K4me1, and H3K27me3 signal at enhancers (center ± 5 kb). Enhancers were classified into active, bivalent, primed, and poised based on their accessibility and histone marks in worker brains. The y axis represents raw counts per million (CPM) for ATAC, or scaled, IgG-normalized CPM (for CUT&Tag, see methods). (F) Comparison of assignments of enhancers to target genes using Micro-C and with proximity assignment method. Numbers of active, bivalent, primed, and poised enhancers (as defined by their chromatin state in worker brains) for which gene target assignment using Micro-C and proximity coincided (“match with proximal”), matched to multiple promoters including the proximal promoter, or matched to distal promoters. The number of biological replicates for all analyses is shown in panel (A).
