Genetic Evolution and Biological Characteristics of Feline Caliciviruses Isolated from Dogs

Figure 3

The complete genome recombination analysis of strain canine/GXHC01-21. (a) Comparison of the genomic similarity of strain canine/GXHC01-21 (query) with R-FCV GX2019 (blue) and ACT2/Samson (orange) using a sliding window. The potential recombination breakpoints are shown as red vertical lines and they are marked with nucleotide sites at the bottom of window; (b) Genetic evolution trees based on every recombinant fragment within canine/GXHC01-21 and the 26 FCV reference strains are shown below the similarity plot. The strain canine/GXHC01-21 is marked with a “red circle”, the major parental strain, GX2019, is marked with a “blue triangle”, and the minor parental strain, ACT2/Samson, is marked with an “orange square”.
