Maximum-likelihood trees of the NS4-7 and RdRp gene. The trees were constructed based on the full-length amino acid sequences of (A) the p32 (NS4) protein, (B) the viral genome-linked protein (NS5), (C) protease–polymerase (NS6-7), and (D) RdRp. Bootstrap support values greater than 50 are shown. Sequences reported in this study are highlighted in red.
