Fig 5. Schematic representation of putative genomic compositions of the four H4N6 AIVs isolated in this study and their possible parent viruses.

The eight gene segments (from top to bottom) in each virus are PB2, PB1, PA, HA, NP, M, and NS. Each color represents a separate virus background. The simplified schematic illustration is based on nucleotide-distance comparison and phylogenetic analysis.
