Bun = R. bungei, can = R. cantoniensis, bro = R. brotherusii. Numbers before species pairs correspond to the sheet numbers in Table S2.
ML = maximum likelihood method with model averaging; YN = approximate method with YN model
aFilter = removing orthologous pairs with dS < 0.01, dS > 1.0, dN > 1.0, aligned length < 150 bp.
bestimated using orthologous pairs after filter.
cestimated using the orthologous pairs with dN/dS > 0.5 and P < 0.05, orthologous pairs with possible alignment problems were excluded. Numbers in brackets indicate mean length of orthologs (including alignment gaps).
