Fig. 6: Relationship between DNA methylation and gene expression levels in the photoperiodic tuberization process.

a Histogram shows the number of differentially methylated genes (DMGs) that were also differentially expressed in the Zeb treatment vs the control at each timepoint in E26. b–d The relationship between DNA methylation levels and their expression levels based on the genes overlapping with DMGs and DEGs in E26 at different timepoints. Red spots represent the genes that are negatively correlated with their DNA methylation levels (downregulated methylation levels accompanied by upregulated expression levels and upregulated methylation levels accompanied by downregulated expression levels), while blue spots represent genes with a positive correlation (downregulated methylation levels accompanied by downregulated expression levels and upregulated methylation levels accompanied by upregulated expression levels)
