The sites for the restriction enzymes BamHI, BglI, HindIII, PstI, PvuII, and SstI on the linear DNA genome of Shope fibroma virus, a tumorigenic poxvirus of rabbits, have been determined by digestions of the cloned BamHI and HindIII restriction fragments and by hybridization of 32P-labeled cloned fragments to Southern blots of Shope fibroma virus DNA cleaved partially or completely with the various enzymes. The linear genome is shown to be 160 kilobases in length and to possess terminal inverted repeat sequences of between 12.2 and 12.5 kilobases extending inwards from the cross-linked DNA telomeres. The fine map of the Shope fibroma virus terminal inverted repeats has been constructed and shown to be distinctly different from that of members of the orthopoxvirus group, such as vaccinia, by the absence of detectable tandemly repeated sequences near the termini and by the lack of detectable sequence homology with vaccinia termini.
