Nucleotide and amino acid variability of the 17 O/SEA/Mya-98 FMDV genome sequences obtained from East Asia. Graph (a) shows cumulative nucleotide (including [black] and excluding [black dots] the gap in the S fragment of the 5′- UTR) and amino acid (grey) substitutions against nucleotides occurring along the genome. Synonymous and nonsynonymous substitutions (mean values from a window of 25 residues sliding by an increment of one-codon) across the genome are also shown (b).
