title: Molecular Cloning and Physical Mapping of Restriction Endonuclease Fragments of Autographa californica Nuclear Polyhedrosis Virus DNA.
abstract: A restriction fragment library containing Autographa californica nuclear polyhedrosis virus (AcNPV) DNA was constructed by using the pBR322 plasmid as a vector. The library, which is representative of more than 95% of the viral genome, consists of 2 of the 7 BamHI fragments, 12 of the 24 HindIII fragments, and 23 of the 24 EcoRI fragments. The cloned fragments were characterized and used to generate physical maps of the genome by hybridizing nick-translated recombinant plasmid to Southern blots of AcNPV DNA digested with SmaI, BamHI, XhoI, PstI, HindIII, and EcoRI restriction endonucleases. This information was used to define our strain of AcNPV (HR3) with respect to other strains for which physical maps have been previously published. The hybridization data also indicate that reiteration of DNA sequences occurs at the HindIII-L and -Q regions of the genome.
