M viral RNA segment of bunyaviruses codes for two glycoproteins, G1 and G2

Tryptic peptide digests of the two viral glycoproteins (G1 and G2) of snowshow hare (SSH) virus, La Crosse, La Crosse (LAC) virus, and an SSH/LAC recombinant virus which has a large (L)/medium (M)/small (S) RNA segment genome composition of SSH/LAC/SSH were analyzed by ion-exchange column chromatography. The analyses prove that the M RNA species of bunyaviruses codes for the two viral glycoproteins.
