Fig. 2. Association between 6mA and chromatin organization.
a 6mA is mostly found in linker regions. 6mA, and hence, MACs are frequent in nucleosome-free regions, as exemplified in this genome snapshot (scaffold 3:1062358-1068209). b 6mA frequency over linker and nucleosome regions. Both regions were scaled and divided into ten equal-sized bins. c 6mA and nucleosome dyads profiles with respect to TSS, including 0.5 kb upstream and downstream regions. d Methylated genes display a more consistent fixed distribution (left) than unmethylated genes (right). Normalized occupancy of nucleosome dyads was plotted in reference to TSS, including 1.5 kb flanking regions. A heatmap with the average normalized occupancy signal is also displayed below. Kolmogorov-Smirnov test (KS) was performed to evaluate differences between frequency distributions (P < 0.001) (n = 1732 genes and 1149 genes for methylated and unmethylated genes, respectively). Source data are provided as a Source Data file.
