Fig. 2

DNA methylation profiles and levels of gene and TE regions in leaf and root tissues of switchgrass. a DNA methylation patterns in gene regions. b DNA methylation patterns in TE regions. The average methylation level for each 100-bp interval is plotted. The dashed lines for gene and TE regions indicate the transcriptional start (left) and end (right) sites. AL and AR indicate leaf and root tissues, respectively, in switchgrass. c Comparison of DNA methylation levels between leaf and root tissues of switchgrass in gene and TE body and their flanking regions (2-kb), respectively. * means the p < 0.05. ** means the p < 0.01
