    Snippet: To assess adaptive evolution of MERS-CoV, dN/dS ratios (ω) in S gene across the 219 strains were calculated on codon-by-codon basis. The overall ω was 0.424737 (0.392404 and 0.439492 for clade A and B strains, respectively), with most codons having ω < 1, indicating purifying selection (Table 2) . Nevertheless, four codons were predicted to have ω > 1 by different methods with statistical significance, including codons 26 and 312 by fixed ef.....

The overall ω was 0.424737 (0.392404 and 0.439492 for clade A and B strains, respectively), with most codons having ω < 1, indicating purifying selection (Table 2) . Nevertheless, four codons were predicted to have ω > 1 by different methods with statistical significance, including codons 26 and 312 by fixed effects likelihood (FEL) method, codon 1250 by mixed-effects model of evolution (MEME) method, and codon 1224 by both FEL and MEME methods, indicating possible functional constraints at these positions during evolution. Among them, codons
