FIG. 1.

Genomic organization of sobemoviruses. ORFs are illustrated as boxes. VPg, the peptide covalently attached to the 5′ terminus of the RNA genome, is shown as a small circle. The approximate locations of the putative protease and putative RdRp domains are labeled Pro and RdRp, respectively. The sites of −1 ribosomal frameshift consensus signals are indicated by vertical chains. The positions of the first AUGs in ORF3 of SCPMV, SBMV-Ark, RYMV, and LTSV and in ORF2b of CfMV are indicated by short vertical lines. P1, ORF1-encoded protein; CP, coat protein.
