Abstract

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.

摘要

采用变性凝胶电泳分析了传染性造血坏死病毒的基因组RNA和六种mRNA。测定了以下分子量:基因组RNA为3.7×10⁶;mRNA 1为2.26×10⁶;mRNA 2为5.63×10⁵;mRNA 3为4.84×10⁵;mRNA 4(包含两种不同的mRNA)为3.00×10⁵;mRNA 5为1.95×10⁵。利用凝胶密度计分析计算细胞内mRNA的摩尔比:mRNA 1为0.02;mRNA 2为0.49;mRNA 3为1.0;mRNA 4为2.52;mRNA 5为0.41。杂交筛选研究确定了mRNA的编码分配如下:mRNA 1编码病毒聚合酶L;mRNA 2编码糖蛋白G;mRNA 3编码核衣壳蛋白N;mRNA 4由两种共迁移的mRNA组成,编码基质蛋白M1和M2;mRNA 5编码一种以前未识别的病毒蛋白,该蛋白在感染细胞中被诱导产生,但不存在于成熟病毒粒子中。这种非病毒粒子蛋白被命名为NV蛋白。
