Abstract
Murine cytomegalovirus RNA synthesis in productively infected mouse embryo cultures was measured by reassociation kinetics with iodinated viral DNA. The data were analyzed by a computer program and indicated the following: before DNA replication approximately 25% of the genome was transcribed into asymmetric transcripts, of which slightly fewer than half of the sequences were recovered from the cytoplasm. After viral DNA replication, approximately 38% of the genome was transcribed (5% as symmetric transcripts), and again less than half of the sequences appeared in the cytoplasm. Both early and late RNA comprised two abundance classes differing about 8- to 10-fold in concentration. Early RNA was a subset of late RNA. The RNE sequences synthesized in late-infected cells in the presence of cytosine arabinoside or cycloheximide were similar to early RNA. Thus, murine cytomegalovirus displays temporal, quantitative, and post-transcriptional controls over gene expression, but the pattern differs considerably from herpes simplex virus.
