Figure 1. Phylogenetic tree for influenza A virus proteins encoded by the M gene. (A) Amino acid constructed tree for M1 proteins. (B) Amino acid constructed tree for M2 proteins. The strains whose complete names are given are those obtained from Genbank. The strains analyzed in this study are indicated by numbers or abbreviations listed in Table 1. The symbol @ indicates strains isolated from wild ducks, whereas the symbol + indicates shorebird and gull isolates. The scale is in number of nucleotide substitutions per site. Vertical lines are for spacing branches and labels; their lengths are not significant. Strain abbreviations are listed in Table 1. DE: Delaware, NJ: New Jersey. Tree (pdf)
