Fig. 2From: Molecular epidemiology and viremia of porcine astrovirus in pigs from Guangxi province of ChinaNucleotide 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 studyBack to article page
