Edwardsiella Comparative Phylogenomics Reveal the New Intra/Inter-Species Taxonomic Relationships, Virulence Evolution and Niche Adaptation Mechanisms
Figure 6
Genome-wide nucleotide variations among the orthologs of sequenced Edwardsiella strains.
(A) Nucleotide diversity (π) for 8 Edwardsiella strains. The black line represents the average π value of all orthologs. Green line indicates π values above 1.5σ (standard deviation) from the average π values of all orthologs, respectively. The percent of genes with π values large than 1.5σ from the average π value in each function category are shown under x axis. (B) Analysis of the ratio of nonsynonymous (NonSyn) to synonymous (Syn) SNP rates according to the RAST-annotated categories. The set of genes which contain significant high ratios (p<0.05) of nonsynonymous (NonSyn) SNPs than synonymous (Syn) SNPs between E. tarda EdwGI and E. tarda EdwGII strains were as indicated.
