Characteristics of A/B compartments and I regions in 27 soybean accessions. a Examples of Hi-C contact maps and E1 value tracks of chromosomes in soybean accessions. The red bars of E1 value tracks represent the A compartments, and the blue bars of E1 value tracks represent the B compartments. b A compartment percentages across chromosomes in 27 soybean accessions. Each dot represents one chromosome. Data are mean ± s.d. c Correlation analysis of A compartment percentages across chromosomes and GC contents, TSS densities and repeat percentages. d I region percentages across chromosomes in 27 soybean accessions. Number in parentheses indicates the average number of I regions. Each dot represents one accession. Data are mean ± s.d. e Violin plot of GC contents, TSS densities, and repeat percentages across chromosomes in A regions, B regions, I regions, I regions-A (A compartments in I regions) and I regions-B (B compartments in I regions) in 27 soybean accessions. Boxes represent the 25th, 50th, and 75th percentiles, and whiskers represent 1.5× the interquartile range. Multiple comparisons were performed with one-sided Wilcoxon rank-sum test with Benjamini–Hochberg multiple testing correction
