The p10 ORF was located in the EcoR I-R fragment. Initiation codon ATG of p 10 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 p 10 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.展开更多
