Recent comparisons of 34 angiosperm methylomes show that genome-wide methylation levels (GMLs-a measure of the percentage of all cytosines that are methylated) can vary substantially between species even within the same taxon (Fig. 1a see Additional file 2: Figure S1 for GMLs measured by HPLC and WGBS-seq). They range from as low as 5% in Theobroma cacao to as high as 43% in Beta vulgaris, with a mean of about 16% [primary sources]. While multiple factors probably contribute to these differences, interspecific variation in genome size is a strong predictor ([primary sources] see Fig. 1b)."
