Schematic diagram of the Aichi virus genome and the predicted secondary structure of the 5′-end 180 nucleotides of the genome. The thick lines and open box indicate the untranslated regions and coding region, respectively. Vertical lines within the box represent putative cleavage sites for viral proteinases. The three stem-loop structures were designated SL-A, SL-B, and SL-C, and another stem-loop structure (nt 111 to 164) downstream of SL-C was predicted.
