title: Identification of the N and NSS proteins coded by the ambisense S RNA of Punta Toro phlebovirus using monospecific antisera raised to baculovirus expressed N and NSS proteins.
abstract: An essentially complete DNA copy of the ambisense S RNA species of Punta Toro (PT) phlebovirus (T. Ihara, H. Akashi, and D.H.L. Bishop, 1984, Virology 136, 293-306) has been inserted in either orientation into Autographa californica nuclear polyhedrosis baculovirus (AcNPV) in lieu of the 5' coding region of the AcNPV polyhedrin gene (G.E. Smith, M.D. Summers, and M.J. Fraser, 1983, Mol. Cell. Biol. 3, 2156-2165). The two types of recombinant viruses were used to infect Spodoptera frugiperda cells and the expressed PT viral proteins characterized. Recombinant AcNPV having the S DNA in one orientation expressed PT virus N protein in amounts estimated to represent some 50% of the infected cell extracts, whereas recombinants with the S DNA in the other orientation expressed the putative PT virus NSS protein in lower quantities. Antisera that were monospecific with respect to each of the two PT proteins virus were raised in mice using the corresponding S. frugiperda infected cell extracts and were employed to identify N and NSS proteins in PT virus-infected Vero cells.
