FIG. 3.
Genome organization and calculated length of the shortest subgenome (R-cp 1; top) and the largest genome (R-cp 46; bottom) obtained by RNA recombination between NCP7 and +ubi SGT. For the latter recombinant genome, the region between the Npro gene and the 5′-terminal NS5B coding gene is indicated by dots. Both recombinant RNAs contain ubiquitin-coding sequences (gray box) derived from +ubi SGT. The lengths of the bars are not drawn to scale. The underlined parts of the genomes have been sequenced.
