Nucleotide sequence similarities (figure 2a) and numbers of nucleotide differences (figure 2b) among VGS species when analyzing groEL and groES sequences from the study by Teng et al [7], or regions R1 and R2 chosen using SVARAP to discriminate between the different VGS species. ^a For sequences obtained by Teng et al., the numbers of nucleotide differences among VGS species were calculated based on the nucleotide sequence similarities and the sequence lengths published [7]. ^b Partial groES-including sequences chosen using SVARAP (R1) were analysed to calculate sequence similarities considering or not considering positions in the alignment where at least one sequence does not harbor a nucleotide (gaps).
