Table 3. Site-specific selection analysis for each coding gene of vaccine- and nonvaccine-related groups.
| Gene | Total number of codons | Global dN/dS*(codon position¶) | |
| Vaccine-related group | Nonvaccine-related group | ||
| NP | 489 | 0.119 (None) | 0.100 (467§) |
| P | 395 | 0.266 (None) | 0.336 (87§, 90§, 380§) |
| M | 364 | 0.176 (None) | 0.123 (None) |
| F | 553 | 0.166 (115¥) | 0.139 (28†) |
| HN | 616 | 0.166 (266§, 495†, 522†) | 0.171 (508§) |
| L | 2204 | 0.088 (None) | 0.094 (None) |
Strains used for selection analyses in both groups are mentioned in Table S1.
¶: Position of codon under positive selection with p<0.05.
¥: Significant in PAML analysis.
§: Significant in FEL analysis.
†: Significant in both FEL and PAML analysis.
*: Rate of Non-synonymous (dN) to Synonymous (dS) substitution.
