Outline of Final Research Achievements |
Bombyx mori nucleopolyhedrovirus (BmNPV) H4 that had genome sharing high sequence similarity (approx. 97%) with that of the type strain of BmNPV T3 showed marked growth advantage in silkworm larvae. Studies using chimeric recombinant BmNPV between H4 and T3 demonstrated that a viral membrane protein gene gp64 as a determinant in the in vivo fitness of BmNPV H4. Further analyses identified amino acid positions involved in the BmNPV H4 phenotype of efficient growth in silkworm larvae. These results suggested the possibility to control growth ability of BmNPV in silkworm larvae by gp64-targetted genome manipulation.
