Bayesian MCC phylogenies and between-regions diffusion networks on PB2 gene segment of AIV in China. The sequences are classified according to their variant designation in (1) TR: Traditional geographic regions; (2) ED: Economic divided zones. Branches are coloured according to their descendent nodes annotated by the different sampled areas within the region type, with the key for colours shown on the left. a Tree phylogeny with branches coloured according to the Tradition regions. b Tree phylogeny with branches coloured according to the Economic divided zones
