Physical maps of bovine papillomavirus type 1 and type 2 genomes.

Physical maps of bovine papillomavirus type 1 and type 2 (BPV-1 and BPV-2) DNA were constructed from analysis of the electrophoretic mobilities of restriction endonuclease cleavage fragments from dual digests. BPV-1 DNA was sensitive to Hind III, HindIII, EcoRI, HpaI, AND BamHI, with all but HindII yielding single scissions. BPV-2 DNA was resistant to EcoRI, and HindIII had one cleavage site whereas HpaI, BamHI, and HindII yielded multiple fragments. Of four BPV-1 isolates examined, DNA from one isolate was resistant to HindIII, and another DNA isolate was resistant to BamHI. The three BPV-2 isolates examined were uniformly sensitive to the restriction endonucleases employed.
