Fig. 1.

Schematic representation showing the partial genome organization and nucleotide alignment of the newly identified PAstV strain JWH-1. a All ORFs, the 5′ UTR, the 3′ UTR and the polyA tail are shown in the diagram. Dotted lines represent uncharacterized regions. b Nucleotide sequence alignment of the conserved sequence at the ORF1b/ORF2 junction of the JWH-1 strain with those of prototypical PAstVs. The ATG initiation codon is indicated by asterisks. c Nucleotide sequence alignment of the conserved sequence motif at the 3′ ends of the JWH-1 strain with those of prototypical PAstVs. The ORF2 stop codon is indicated by asterisks. The stem-loop-II-like motif (s2m) is indicated by a red frame
