Construction and Characterization of a Novel Bacmid AcBac-Syn Based on a Synthesized Baculovirus Genome.

ABSTRACT: Baculoviruses are large DNA viruses which have been widely used as expression vectors and biological insecticides. Homologous recombination and Bac-to-Bac system have been the main methods for manipulating the baculovirus genome. Recently, we generated a synthetic baculovirus AcMNPV-WIV-Syn1 which fully resembled its parental virus Autographa californica multiple nucleopolyhedrovirus (AcMNPV). Here, we report the modification of AcMNPV-WIV-Syn1 into a novel bacmid, AcBac-Syn, which can be used as a backbone for Bac-to-Bac system. To achieve this, a vector contained a LacZ:attTn7 and egfp cassette was constructed, and recombined with a linearized AcMNPV-WIV-Syn1 genome by transformation-associated recombination in yeast to generate bacmid AcBac-Syn. The bacmid was then transfected to insect
