Nucleotide alignments between porcine astroviruses of this study and reference strains. (a) Schematic representation of the complete astrovirus. ORF1a, ORF1b and ORF2, 5ˊ UTR, 3ˊ UTR and poly A are shown. (b) Nucleotide alignment of the conserved sequence at the junction of ORF1b/ORF2, the proposed beginning and end of the conserved sequences was indicated by ▼; The ATG initiation codons are indicated by the black box. (c) Nucleotide alignment of a highly conserved motif located in the 3ˊ end of the genome of PAstVs. The conserved sequences in s2 m are indicated by the red box, and the ORF2 stop codons are indicated by black box. The arrows indicate AstV strains characterized in this study
