The use of boldface indicates that sequences with 100% identity to a reference were detected for all MLV target regions in a mouse. The use of italics indicates that more than one Mpmv sequence in a cluster was 100% identical. Mpmv reference sequences are those of Bamunusinghe et al. [4]. A dash indicates that for a target MLV region, the region is deleted in the reference sequence relative to other MLV sequences
