Pairwise sequence divergence of the whole genome and protein coding regions in the subfamily Lemnoideae compared with those of the subfamily Pooideae (wheat, barley and Brachypodium).

aSubstitution Rates = substitution/alignment length;bsi (Transitional Pairs) = AG+CT;csv (Transversional Pairs) = TA+TG+CA+CG;dINDELs Ratio = INDELs length/alignment length. AG means A is mutated to G and others follow the same rules. S.pol = S. polyrhiza, L.min = L. minor, W.lin = W. lingulata, W.aus = W. australiana, B.dis = B. distachon
