A) Bayesian phylogenetic tree of envelopes genes of all described Arizona, USA, 2010 isolates of West Nile virus (WNV) (n = 15). Isolates grouped in 3 distinct monophyletic clusters designated A (red), B (blue), and C (green). B) Bayesian phylogenetic tree of full-length encoded open reading frame for 3 Arizona, USA, 2010 isolates: AZ10.581 (red), AZ10.892 (green), AZ10.91 (blue), and 100 representative North American WNV isolates. All applied relaxed clock Bayesian methods used the generalized

Figure 2. . A) Bayesian phylogenetic tree of envelopes genes of all described Arizona, USA, 2010 isolates of West Nile virus (WNV) (n = 15). Isolates grouped in 3 distinct monophyletic clusters designated A (red), B (blue), and C (green). B) Bayesian phylogenetic tree of full-length encoded open reading frame for 3 Arizona, USA, 2010 isolates: AZ10.581 (red), AZ10.892 (green), AZ10.91 (blue), and 100 representative North American WNV isolates. All applied relaxed clock Bayesian methods used the generalized time reversible + invariant sites + Γ4 substitution model with a lognormal molecular clock and triplicate 50 million state runs produced in BEAST v1.6.2 (3). Inferred phylogenetic trees were edited in FigTree v1.3.1 (http://tree.bio.ed.ac.uk/software/figtree/). Consistent phylogenetic topologies with additional neighbor-joining and maximum-likelihood methods further validated these inferred relationships. Posterior probabilities ≥0.90 are indicated for highlighted nodes. Scale bars indicate divergence time in years.
