DNA methylation level is negatively associated with lncRNA expression in F1 hybrid. a Pie chart showing the distribution of differently methylated regions (DMRs) of lncRNAs in categories of CG, CHG, and CHH in F1 hybrid. LncRNAs were classified into groups of equal expressed (Equal, n = 2610), upregulated (Up, n = 1,302, p < 0.01, fold change > 2), and downregulated (Down, n = 1,272, p < 0.01, fold change < 0.5). b Histogram showing the proportion of hyper- and hypo-methylation on DMRs in lncRNAs. LncRNAs were classified into groups the same with a. c DNA methylation (CG, CHG) profile of equal expressed (Equal), upregulated (Up), and downregulated (Down) lncRNA in hybrid. Red and blue represent parent and F1, respectively. d Correlation between differential gene expression (p < 0.01 and fold change > 2.0) and differential DNA methylation (p < 0.01). e Example of F1-upregulated lncRNA, XLOC_035525.
