p10 genes of Bombyx mori nuclear polyhedrosis virus and Autographa californica multiple nuclear polyhedrosis virus.
EcoR I-P fragment has been cloned from Autographa californica multiple nuclear polyhedrosis virus (AcMNPV) genomic DNA and used as a probe. 0.5-kb and 1.1-kb fragments including p10 gene from Bombyx mori nuclear polyhedrosis virus (BmNPV) have been hybridized. The p10 ORF was located in the EcoR I-R fragment. Initiation codon ATG of p10 from BmNPV has been mutated by PCR, and the ATG region became a Bgl II site. A novel transfer vector pBmAcPV-1 has been constructed using both the p10 5'-flanking region whose initiation codon ATG has been mutated with BmNPV and the p10 3'-flanking region of AcMNPV. The vector can recombine with not only AcMNPV DNA to express foreign gene in Sf cells, but also BmNPV DNA to express foreign gene in Bm cells. CAT gene was expressed at high level in Bm cells under the control of the mutated p10 promoter of BmNPV.
