title: Absence of interaction of genomic components and complementation between Mungbean yellow mosaic India virus isolates in cowpea.
abstract: Agroinoculations were performed with DNA A and DNA B components of Mungbean yellow mosaic India virus (MYMIV) isolates differing in their infectivity on cowpea. Exchange of genomic components of the MYMIV isolates occurred in all the leguminous species but not in cowpea. Extremely low viral DNA accumulation and atypical leaf curl symptoms produced by reassortants in cowpea suggest barriers both for replication and systemic movement despite genetic similarity.
