Abstract:
A physical map for the DNA genome of insect iridescent virus type 9 isolated from Wiseana spp. larvae [Lepidoptera: Hepialidae] was constructed using the restriction enzymes BamHl, EcoRl, and Pstl. Viral DNA was cloned into the plasmids pBR328 and pUC8 using Escherichia coli strains HB101 and JM83, respectively. The physical map for BamHl, EcoRl, and Pstl was constructed by multiple enzyme analysis and Southern hybridization of cloned viral DNA. Statistical analysis of restriction data by computer-aided linear modeling supported the physical map produced and indicated a total genome size of 192.5 kb. Due to the cyclic permutation of iridescent virus genomes the map is presented in a circular form.
