J-10, a strain of bean pod mottle virus (BPMV), was efficiently transmitted by the bean leaf beetle, had the same host range as BPMV, and contained the three typical centrifugal components. J-10 differed from BPMV serologically and in the symptoms produced in Chenopodium quinoa. Separation of middle (M) and bottom (B) centrifugal components of both virus isolates and remixing increased lesion counts, whether the mixtures were homologous or heterologous. Soybean plants were inoculated with extracts from local lesions obtained from homologous and heterologous combinations of the M and B of J-10 and BPMV. The mixtures containing J-10 M produced infections which gave serological reactions characteristic of J-10 virus, indicating that the genetic information for the antigenic characteristics of the protein is carried by M.
