Differentially methylated regions and GO analysis. a Methylation and expression level on different genome elements. X axis represents different treatments (CK, drought stress and re-watering), and Y axis represents methylation levels or FPKM-log_ratio of genes. Red was methylation level and green was gene expression level. The calculation method used in the process was FPKM_log_ratio = log10(FPKM(k))/log10(max(FPKM)). b Number of DMRs under drought stress. c GO enrichment analysis of DMRs. GO analysis contains three branches: Cellular component, molecular function and biological process. Red represents biological process and blue represents molecular function. *Represents statistical significance level at P = 0.05
