Hi-C analyses of chromatin interactions in wild and dwarf mutant peanuts. A Genome-wide chromatin interaction map represented by the wild type (H2014) at 500-kb resolution. The chromosomes are stacked from top left to bottom right in order (chr01, chr02…chr20). Color bars beside heat maps indicate strong interactions in red and weak interactions in white. B Chromatin interactions represented by a single chromosome of the wild type (H2014) at 500-kb resolution. The upper track shows the partitioning of A-compartments (blue histogram) and B-compartments (red histogram). The middle track shows global patterns of chromatin interaction represented by chr04 and chr07, respectively. The lower track shows chromatin interactions in an enlarged region of chr04 and chr07 at 40-kb resolution, respectively. Each triangle distributed diagonally is represented as a topologically associated domain (TAD). C 3D model of whole chromosomes in the wild type (H2014) and the dwarf mutant (H1314). Each color represents one chromosome
