Epidemiological and Molecular Characteristics of the PB1-F2 Proteins in H7N9 Influenza Viruses, Jiangsu

<div>Phylogenetic tree of influenza A viruses for their PB1 gene nucleotide sequences. Sequence analysis was conducted using Molecular Evolutionary Genetics Analysis software by the neighbor-joining method. Note: ●: N-terminally truncated PB1-F2 (52aa); ◆: C-terminally truncated PB1-F2 (76aa); ▲: C-terminally truncated PB1-F2 (57aa).</div>
