Genome recombination analysis of norovirus strains isolated from China in 2021–2022. The full length of the GII.4[P31] (SJZ1007) and GII.4[P16] (SJZ7125) sequence and partial of GII.2[P16] (SJZ8231) and GII.3[P12] (SJZ10110) were used for recombination analysis. RDP4 results show recombination breakpoints and relationships of representative strains to the parental strains. All plots were obtained using a 200 bp sliding window, 284 steps of 20 bp. Sequence locus information is referenced to GII.4 Sydney 2012 genome (JX459908). The horizontal line and vertical lines show nucleotide positions and nucleotide pair- wise identity. A Analysis of GII.4[P31] consensus sequence against Osaka_2007 strain (GenBank: AB541319, purple) and Apeldoorn_2008 strain (GenBank: AB541268, teal), predicted recombination position at 5081nt. B Analysis of GII.4[P16] consensus sequence against Berlin 2000 strain (GenBank: AY772730, purple) and US95_96 strain (GenBank: KC013592, teal), predicted recombination position at 5090nt. C Analysis of GII.2[P16] consensus sequence against Berlin 2000 strain (GenBank: AY772730, teal) and Tokyo 2004 strain (GenBank: DQ456824, purple), predicted recombination position at 5068nt. D Analysis of GII.3[P12] consensus sequence against Saitama 2002 strain (GenBank: AB039775, teal) and Mexican 1995 strain (GenBank: U22498, purple), predicted recombination position at 5039nt
