Figure 3.

Window analysis calculating dN/dS between GAS and SDSE. dN/dS was calculated as the ratio of nonsynonymous (dN) to synonymous (dS) substitution rates of gene pairs in speG (A) and pgi (B) from GAS and SDSE genomes. The figure shows only the results of comparisons between SSI-1 (GAS) and GGS_124 (SDSE). The X-axis represents nucleotide position.
