Tracing the Origin of Genotype II African Swine Fever Virus in China by Genomic Epidemiology Analysis

Figure 5

Pattern of genotype II ASFV single nucleotide polymorphisms (SNPs) distribution. (a) Distribution of SNPs in genotype II ASFV genomes. A total of 277 SNPs show a pattern of genotype II ASFV mutation accumulation, showing one mutation site per column. The strain name is shown at the left, indicating one strain per row. The grey blocks indicate sequence identity with the reference genome Georgia 2007/1 sequence. The top row shows the type of mutation (dark grey, intergenic; green, synonymous; red, nonsynonymous), with the gene location indicated above. Cluster assignment is shown at the left by color. (b) Distribution of 8 anchor SNPs in different cluster of genotype II ASFV genomes. The top row shows the codon position of SNPs with the gene location indicated above. (c) Distribution of amino acid changes of anchor SNPs in different cluster of genotype II ASFV genomes. The top row shows the type of mutation (green, synonymous; red, nonsynonymous), with the gene location indicated above.
