From: Comparative study of codon substitution patterns in foot-and-mouth disease virus (serotype O)

Bar graphs of the exactly matched codon % (EMC) in (A) each synonymous codon group, and in (B) each geographical regions of isolation, such as Europe, Middle East, Asia, Africa, and South America, are shown. All the regional information is presented in Table S1. Each bar represents the % mean, and the error bar indicates the standard deviation. The asterisk means that the value was significantly differed from the value of (A) HIS, or (B) Europe when using Tukey's studentized range test (P < 0.05).
