Distribution of the DMRs between the wild and landrace populations for the 17 pear chromosomes. Proceeding from the outer ring to the inner ring, the data represents TE density (I), gene density (II), dom-CG-DMR density (III), dom-CHG-DMR density (IV), imp-CG-DMR density (V), imp-CHG-DMR density (VI), dom-DSR (VII), and imp-DSR (VIII).
