The percentage of identity for the six internal genes and the divergent viral genotypes isolated in this study.
(a) The identity of the six internal genes of the seven H7N9 viruses and three H9N2 viruses isolated in this study. Each gene formed two groups, assigned as group A and B, based on a sequence similarity higher than 99.6%; those two groups are shown in green. The “mix” marked in the square of the PB2 and MP genes represents a mixture of the amino acids observed in the virus. (b) The mixed amino acids sites of the PB2 gene of virus A/Chicken/Jilin/13204/2014(H9N2) and the MP gene of virus A/Chicken/Jilin/13199/2014(H7N9) are specified. (c) A and B indicates group A and B, respectively and the different combination of groups in each segment represents different viral genotypes. Orange and green indicate the gene segments of the parental H7N9 and H9N2 viruses, respectively.
