RESUMO

The restriction sites of Rachiplusia ou nuclear polyhedrosis virus (RoMNPV) DNA were mapped for the endonucleases SmaI, KpnI, BamHI, SacI, XhoI, and EcoRI. Of the 60 DNA restriction sites of RoMNPV, 35 mapped in similar positions as compared to the restriction sites of Autographa californica nuclear polyhedrosis virus (AcMNPV) DNA. Two plaque-purified viruses, obtained from randomly picked plaques of a wild-type isolate of RoMNPV, were recombinants of RoMNPV and AcMNPV. The recombinants were shown to have RoMNPV and AcMNPV restriction fragments as well as structural polypeptides from each parental virus. Both recombinant viruses had a major RoMNPV capsid protein but were occluded in the AcMNPV polyhedrin protein.
