Distribution of OCEAN-C loops across wheat genome. a OCEAN-C interaction matrix at 1 Mb resolution throughout chromosome 1A. b Venn diagram showing the overlapped peaks of OCEAN-C and ATAC-seq. c Fractions of PPI (green), PDI (orange), and DDI (purple) loops in all identified OCEAN-C loops. d Proportions of proximal and distal peaks in A/B compartments. The windows at 5 kb were randomly selected as random anchors using BEDTools from each chromosome. e Distribution of OCEAN-C anchors (a), chromatin accessibility (b), H3K9ac (c), H3K14ac (d), H3K27ac (e), H3K4me3 (f), H3K27me3 (g), A/B compartments (h), and gene density (i) throughout chromosomes in the hexaploid wheat. f Fractions of OCEAN-C loop anchors overlapped with various histone modification markers and open chromatin regions identified by ATAC-seq. Randomly selected regions were used as control. g Fold-enrichment of TEs in proximal (P) and distal (D) anchors, relative to whole genome. ** indicates P < 0.01 (Hypergeometric test)
