A half of endo-DMRs are methylated in rdd dry seed. a Representative snapshots of endo-DMRs. b A heatmap showing methylation levels within endo-DMRs. Hierarchical clustering classified endo-DMRs into 11 clusters. Numerals at the right side of the heatmap indicate cluster number where each endo-DMR belongs to. Endo-DMRs in clusters 1, 2, 3, 6, 8, 10, and 11 are methylated in rdd dry seed but not in WT dry seed. Embryo and endosperm methylome data are obtained from Hsieh et al.
