Spodoptera frugiperda Nuclear Polyhedrosis Virus Genome: Physical Maps for Restriction Endonucleases BamHI and HindIII

Abstract

The physical map for the genome of Spodoptera frugiperda nuclear polyhedrosis virus was constructed for restriction endonucleases BamHI and HindIII. The ordering of the restriction fragments was accomplished by cross-blot hybridization of BamHI, HindIII, and EcoRI fragments. The alignment of the HindIII fragments within the BamHI map was achieved by double digestion with the two restriction endonucleases followed by cross-blot hybridization. The results showed that the viral genome consisted of mainly unique sequences. In addition, the circular nature of the viral genome was reaffirmed.
