Figure 7From: Host-range shift of H3N8 canine influenza virus: a phylodynamic analysis of its origin and adaptation from equine to canine hostThe Bayesian Skyline plot (BSP) of H3N8 CIV in each segment. BSPs were simulated using the BEAST (V1.8.4) program, based on all eight segments of 44 strains, with a GTR plus gamma nucleotide substitution mode and relaxed molecular clock. The prior tree set as the coalescent: Bayesian skyline with 108 generations. The blue vertical bar indicates the period of divergence of major H3N8 lineages in canine species.Back to article page
