The gene encoding the green fluorescent protein (gfp) under the control of the highly expressed Autographa californica nucleopolyhedrovirus (AcMNPV)- polyhedrin promoter has been introduced into the polyhedrin (polh) locus of Bombyx mori nucleopolyhedrovirus (BmNPV) by homologous recombination. The insect host larvae and the cultured cells infected with this recombinant virus (vBmGFP) showed high levels of expression of gfp. The larval tissues permissive to virus multiplication could be readily visualized using the tagged recombinant virus, thus providing a direct approach to study the progress of virus infection or its control in the animal host. The highly expressed recombinant protein, GFP, could be easily solubilized from fat bodies. Thus, the caterpillar-based expression could serve as an economic alternative method for the large-scale production of recombinant proteins, even when they are nonsecretory in nature. Further, if the recombinant vBmGFP is used as a parent in generating other recombinants, conversion of the fluorescent plaques to colorless plaques serves as an easy means for screening recombinants. Such a method is especially helpful for BmNPV- recombinant selections in the absence of the other simplified techniques as are available for the prototype baculovirus AcMNPV system.

Recombinant Bombyx mori nucleopolyhedrovirus harboring green fluorescent protein

Oxalyl CoA synthetase, a key enzyme in the biosynthesis of β-oxalyl CoA synthetase, a key enzyme in the biosynthesis of days old seedlings of Lathyrus sativus using affinity chromatography and electroelution. The enzyme existed in three forms. They were designated as OCS-1, OCS-2 and OCS-3 and their molecular weights were found to be 63.1, 39.9 and 17.7 kDa, respectively. The antibodies were raised against all the three enzymes. The monospecificity of the antiserum was checked by immunoblotting. OCS-1 and OCS-2 did not share any common epltopes as no cross-reaction was seen. © 1992 Springer-Verlag.
