Use of polyclonal antisera and monoclonal antibodies to examine serological relationships among three filamentous viruses of sweetpotato.

Sweetpotato is susceptible to infection by several filamentous viruses of which only the aphid-transmitted sweetpotato feathery mottle virus (SPFMV) has been well-characterized. Sweetpotato mild mottle (SPMMV; transmitted by whiteflies) and sweetpotato latent (SPLV; for which no vector has been identified) viruses, although well-recognized, have not been definitively classified. The serological relationships among these viruses were re-examined with SPFMV-, SPLV- and SPMMV-specific polyclonal antisera and potyvirus cross-reactive monoclonal antibodies (MAbs) (...)
