Maximum-likelihood phylogenetic trees. A – tree for the whole genome, nucleotide substitution model GTR + G + I; B – tree for the non-structural genes: nucleotides 1–5295, nucleotide substitution model GTR + G + I; C – tree for the structural genes (VP60+VP10): nucleotides 5296–7369, nucleotide substitution model GTR + G + I
