Additional file 2 of The PB1 gene from H9N2 avian influenza virus showed high compatibility and increased mutation rate after reassorting with a human H1N1 influenza virus

Additional file 2: Table S1. Specific indexes (Barcodes) for reassortant viruses from different hosts. Table S2 Primer sequence for segment amplification of HA gene. Table S3 Total substitution frequency (Fi) at every location at HA ORF region. Table S4 The summary of mutation information. Only the locations with Fi > 0.01 were listed. Table S5 The genetic distances of HA from reassortant viruses and WSN strain.附加文件2：表S1。不同宿主重配病毒的特异性标识（Barcodes）。表S2：血凝素（Hemagglutinin，HA）基因片段扩增引物序列。表S3：HA开放阅读框（Open Reading Frame，ORF）区域各位点的总替换频率（Fi）。表S4：突变信息汇总，仅列出Fi＞0.01的位点。表S5：重配病毒与WSN毒株的HA基因遗传距离。
