Validation of dynamic methylation patterns of genic-MULEs. a Distributions of TE content inside the genic-MULE internal sequences with three evolutionary ages. This analysis shows that older genic-MULEs have significantly lower or similar TE content compared with younger elements (Wilcoxon rank sum test, P = 3.006e-5 for Asian & AA, and P = 0.004681 for Asian & AB). b Density distribution of TIR similarity of genic-MULEs with three evolutionary ages in each domesticated Oryza species (O. sativa ssp. japonica, O. sativa ssp. indica, and O. glaberrima) and their wild progenitors (O. nivara, O. rufipogon, and O. barthii, respectively). TIR similarity decreases over time (Wilcoxon rank sum test, P < 0.003). **: P < 0.01, ***: P < 0.001
