Figure 1From: Host-range shift of H3N8 canine influenza virus: a phylodynamic analysis of its origin and adaptation from equine to canine hostML and MCC tree of the HA (A) and NA (B) segments. The ML trees were constructed using the GTR + gamma nucleotide substitution model with 1000 bootstrap replications (A: HA; B: NA). The MCC trees were reconstructed using the HKY + gamma nucleotide substitution model and lognormal relaxed clock. The skyline coalescent model length chain was set at 1 × 108 in length and resampled every 1 × 104 steps (C: HA; D: NA).Back to article page
