Abstract:
:To investigate whether Bombyx mori immunized with Bacillus subtilis spore displaying GP64 escape from the B. mori nucleopolyhedrovirus (BmNPV) attack, a recombinant integrative plasmid named pJS700-GP64 was constructed, which carries a recombinant cotC-Gp64 gene under the control of the cotC promoter. In this study, pJS700-GP64 was transformed into B. subtilis 168 (trp(-)) competent cells, an amylase (amyE) inactivated mutant was selected, and was confirmed to be a double cross-over integrant, cotC-Gp64 fragment of which was integrated into B. subtilis chromosome. Gp64 was expressed on the spore surface and recognized by Gp64-specific antibody. Results of B. mori when challenged with BmNPV indicated that B. mori vaccinated with the recombinant spores possessed resistance to the invasion of BmNPV at some degree.
