(a) Distribution of the estimated synonymous substitutions rate (Ks) between E. curvula and the selected Poaceae orthologous genes. Peaks represent the divergence between E. curvula and the selected species. (b) Distribution of the synonymous substitution rate within each selected genome paralogous genes. The whole genome duplication shared by all the grasses (gWGD) was estimated to occur 90 Mya. The peaks represent the tetraploidization events of E. tef (tWGD) E. curvula (cWGD) and Z. mays (mWGD).
