Higher expression level in genes with more chromatin interactions. a Venn diagram showing the homoeologous PPI overlap between A, B, and D subgenomes. b, c Distribution of chromatin interactions (b) and chromatin accessibility (c) in distal telomeric regions (short arm, R1; long arm, R3), interstitial regions (short arm, R2a; long arm, R2b), and centromere regions (C) of chromosomes. Chromosomes were divided into 1 Mb windows. ** indicates P < 0.01 (Wilcoxon rank-sum test). d The loop numbers (top) and expression levels (bottom, log2(FPKM+ 1)) of genes with different types of OCEAN-C loops and without loop. ** indicates P < 0.01 (Wilcoxon rank-sum test). e Expression levels (log2(FPKM+ 1)) of genes with different levels of chromatin interactions. f The distribution of proximal anchors interacting with various numbers of distal anchors. g The distribution of distal anchors interacting with various numbers of proximal anchors
