Twelve monoclonal antibodies were used to differentiate 11 isolates of soybean mosaic virus by immunoblot analysis of one-dimensional trypsin peptide maps of the virion capsid protein. Although all isolates showed unique patterns that reflected epitopic specificity of the viral coat protein, the virus isolates formed three distinct groups. These results suggest potential for using this approach to study antigenic drift and plant virus epidemiology.
