When inoculum concentrations were increased, the transformants showed a stronger level of protection against CMV-O than against CMV-Y. The substitution of an amino acid residue between CMV-O and CMV-Y, which is presumed to change the conformation of CP, may reflect the difference in susceptibility to these viruses. Furthermore the transgenic tobacco plants showed a significant level of protection against chrysanthemum mild mottle virus, a member of the cucumovirus group but with no serological relationship to CMV. %U https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-74-2-319
