Table 2 Numbers of synonymous and nonsynonymous substitution per site (dN/dS) in H1N1 HA

From: Long intervals of stasis punctuated by bursts of positive selection in the seasonal evolution of influenza A virus

Protein sites dN/dS ratio; tree partition
  All branches Inter-clade branches* Other branches
H1N1 HA 0.20 ± 0.04 0.15 ± 0.08 0.21 ± 0.04
H1N1 HA1 0.22 ± 0.05 0.19 ± 0.12 0.22 ± 0.05
H1N1 HA2 0.15 ± 0.05 0.08 ± 0.09 0.17 ± 0.06
  1. *refers to several branches of the H1N1 HA tree that connect the 2000–2001 clade and the 2000–2004 clade; unlike H3N2, the trunk is not identifiable in the H1N1 tree within the analyzed time interval.
