FIG. 1.

Phylogenetic analysis of deduced amino acid sequences flanking the NS2/NS3 junction. Consensus amino acid sequences of the NS2/NS3 junction region minus insertion sequences were deduced from sequences generated by using primers shown in Table 1. Sequences compared corresponded to amino acid residues 1290 to 1610 in BVDV1-SD-1. The dendrogram was produced by applying the unpaired geometric mean analysis method using the Higgins-Sharp algorithm (CLUSTAL4) supplied in the MacDNASIS software package (Hitachi Software). Calculated matching percentages are indicated at each branch point of the dendrogram.
