From: DNA repair- and nucleotide metabolism-related genes exhibit differential CHG methylation patterns in natural and synthetic polyploids (Brassica napus L.)

a Average methylation levels of total all C, CG, CHG, and CHH across the whole genome. *P < 0.05, by ANOVA. b Violin plot for the distributions of mCG levels, mCHG levels, and mCHH levels of the uniquely mapped reads. These methylcytosines were determined by using a binomial test, and the methylation levels were calculated according to Schultz et al.96. The ordinate represents the methylation level, and the width of each violin represents the density of points under the methylation level. Significant differences (P < 0.01) were detected between all samples by the Wilcoxon rank-sum test. c Average distribution of DNA methylation levels in gene regions and repeat regions. The methylation levels were compared between natural B. napus (ZS11) and synthetic B. napus (P3-2, Y3380, and Y3560) by ANOVA. ***P < 0.001; **P < 0.01; and *P < 0.05. d Proportions of mCs in each context (CG, CHG, and CHH) out of the total mCs
