Abstract
The Spodoptera litura nucleopolyhedrovirus (SpltNPV) antiapoptotic gene Splt-p49 is able to rescue replication of a p35-null Autographa californica nucleopolyhedrovirus (AcMNPV) in AcMNPV-permissive Sf9 cells. In this study, an AcMNPV p35 knockout bacmid was generated through ET homologous recombination in Escherichia coli and designated as vAcP35-KO. The Splt-p49 gene was transposed into the polyhedrin locus of vAcP35-KO to investigate if Splt-p49 has any antiapoptotic activity in the context of AcMNPV infection of AcMNPV-nonpermissive SpLi-221 cells. Our results demonstrated that Splt-p49 could not inhibit the apoptosis induced by AcMNPV infection of SpLi-221 cells when it was under the control of its native promoter. Western blot analysis showed that Splt-P49 was poorly expressed. When the expression of Splt-P49 was under the control of Drosophila hsp70 promoter, the expression of Splt-P49 was advanced, and a higher level of Splt-P49 was detected. As a result, the apoptosis of SpLi-221 cells was inhibited; however, budded-virus production did not improve in comparison with that in AcMNPV-infected SpLi-221 cells. These data indicated that there are other barrier(s) to AcMNPV replication in the nonpermissive SpLi-221 cells besides apoptosis.
