Characterization of infectious hematopoietic necrosis virus mRNA species reveals a nonvirion rhabdovirus protein.
The genome RNA and six mRNA species of infectious hematopoietic necrosis virus were analyzed by denaturing gel electrophoresis. The following molecular weights were determined: genome RNA, 3.7 X 10(6); mRNA 1, 2.26 X 10(6); mRNA 2, 5.63 X 10(5); mRNA 3, 4.84 X 10(5); mRNA 4 (containing two different mRNA species), 3.00 X 10(5); and mRNA 5, 1.95 X 10(5). Densitometer analyses of gels were used to calculate the molar ratios of the intracellular mRNA species: mRNA 1, 0.02; mRNA 2, 0.49; mRNA 3, 1.0; mRNA 4, 2.52; and mRNA 5, 0.41. Hybrid selection studies determined the mRNA coding assignments as follows: mRNA 1 encodes the viral polymerase, L; mRNA 2 encodes the glycoprotein, G; mRNA 3 encodes the nucleocapsid protein, N; mRNA 4 is composed of two comigrating mRNA species which encode the matrix proteins, M1 and M2; and mRNA 5 encodes a previously unrecognized viral protein which is induced in infected cells but is not present in mature virions. This nonvirion protein has been designated the NV protein.
