Fig. 3From: Co-circulation of multiple reassortant H6 subtype avian influenza viruses in wild birds in eastern China, 2016–2017Phylogenetic tree of the PB2, PB1, PA, NP, M, and NS genes. The PB2 (a), PB1 (b), PA (c), NP (d), M (e), and NS (f) genes of the H6 subtype AIVs from this study are indicated by black circles and the selected representative strains are shown in different colours. The neighbor-joining tree was constructed as shown in Fig. 2Back to article page
