title: Structure of the cauliflower mosaic virus genome. III. Restriction endonuclease mapping of thirty-three isolates.
abstract: The sites of various restriction endonucleases were mapped on the DNA of cauliflower mosaic virus isolate Cabb B-JI.FspAI,HgiAI,HhaI, andXhoI each cut at one site,PstI andPvuII each at two sites,BglII at five sites, andHindIII at nine sites;SacP,SmaI, andXbaI did not cut this DNA. These sites and those ofBamHI,EcoRI, andSalGI were compared with the sites of these enzymes on the DNAs of 32 other CaMV isolates. Considerable variations were found both in numbers and map positions of the sites of the restriction enzymes. The significance of this variation is discussed.
