Figure 4.

Phylogenetic tree constructed using the amino acid sequences of the VP1 protein of representative sequences of all accepted genera of the Caliciviridae family, TsCV (highlighted in green) and its closest relatives, found by analysis of VP1 protein homologues. The scale bar corresponds to the expected mean number of nucleotide substitutions per site. The support value of the TsCV branch is 58 (not shown). The (^) denotes sequences presumably misclassified into the genus Bavovirus; see Section 3.2.
