Competitive between g1GD15-PB2 and f98SH14-PB2 genes during coinfection. (A) Schematic representation of coinfection experiment. MDCK cells were infected with GD15-PB2SH14 at the MOI of 0.01 and WT-GD15 viruses at the MOI of 0.01 or 0.005; (D) Schematic representation of coinfection experiment. MDCK cells were infected with GD15-MSH14 and GD15-M SH14PB2SH14 viruses at the same MOI of 0.01; (B, C & E) Quantitative analysis of g1GD15-PB2 and f98SH14-PB2 genes in supernatants of the coinfected cells by qRT-PCR. Data are presented as mean ± SD (n = 3). The statistically significant differences were analyzed by ANOVA (*P < 0.05; **P < 0.01; ***P < 0.001)
