Abstract

In previous communications we reported that the eight RNA segments of influenza A/PR/8/34 (HON1) virus could be distinguished from corresponding segments of influenza A/Hong Kong/8/68 (H3N2) virus by migration on polyacrylamide-urea gels. Examination of the RNA patterns of the two parent viruses and recombinants derived from them in concert with serological identification of surface proteins and analysis of the other proteins on sodium dodecyl sulfate gradient gels permitted the identification of the genes coding for hemagglutinin, neuraminidase, and the P1, P2, and P3 proteins (Palese and Schulman, 1976; P. Palese et al., Virology, in press). In the present report we have extended these observations using similar techniques to examine other recombinants and have identified the genes coding for the remaining virus-specific moving RNA segment as 1) and segment 6 of Hong Kong virus coding for the respective nucleoproteins, and that segment 7 of both viruses codes for the membtane protein and RNA segment 8 codes for the nonstructural protein. This completes the mapping of the influenza A virus genome.
