We have cloned eight intergenic regions from the Pneumovirus pneumonia virus of mice that link the nine small and medium sized genes previously described (Chambers et al., 1990). The nucleotide sequences of the clones confirm the locations of these genes and their mRNA transcripts in the viral genome. The intergenic regions vary in size from 2-56 nucleotides and show only faint homology to each other or to their analogues in respiratory syncytial virus. Sequence alignments suggest that the location of the transcriptional start site for the mRNA encoding the major nucleocapsid protein of pneumonia virus of mice and respiratory syncytial virus may have altered during virus evolution by gain or loss of a transcriptional start signal.
