Abstract: We constructed a series of gene knockout BmNPVs (KOVs) for each of 141 genes using the BmNPV T3 bacmid system and lambda red recombination system. In a subsequent analysis of the properties needed for infection using a marker gene, egfp (enhanced green fluorescent protein gene), inserted into the polyhedrin locus, the knockout viruses (KOVs) were subdivided into four phenotypic types, A to D. Type-A (86 KOVs) showed the ability to expand infections equivalent to the control while type-B (8 KOVs) spread infections more slowly. Type-C (37 KOVs) expressed egfp in transfected-BmN cells but the production of infectious viruses was not observed. Type-D (10 KOVs) showed no ability to express egfp even in the transfection experiments. KOVs lacking genes (pkip (Bm15), gp41 (Bm66), bro-d (Bm131), Bm20, 48, 65, 91, 93, or 101) previously identified as being essential, were placed in the viable type-A and B categories.
