Heatmap of expression of methylation-related genes. Heatmap of expression of 33 methylation-related genes in 10 species. In three early plants - C. reinhardtii, P. patens and S. moellendorffii, the whole plant was used; in basal angiosperm A.trichopoda, 3 dicots and 3 monots, the leaf tissue was used. The heatmap was presented using the R package pheatmap. 3 and − 3 represents the maximum and minimum values of normalized gene expression level, respectively. The red color in the heatmap shows high expression and the green color in the heatmap shows low expression
