Fig. 5.

The structures of partial S protein sequence-containing BCoV DVGs identified during diverse selection pressures. Deleted or mutated nucleotides are indicated with yellow or red lines, respectively, when compared with the full-length genome. The numbers shown in each DVG structure are the nucleotide positions corresponding to the full-length genome. The dashed line indicates the truncated genome in the DVG. Numbers on both sides of the dashed line indicate the recombination positions corresponding to the full-length genome.
