Abstract:
Spodoptera littoralis cells infected with the Autographa californica multiple nuclear polyhedrosis virus (AcMNPV) yielded significantly lower budded virus titers than Spodoptera frugiperda-infected cells and produced very low levels of polyhedrin. Relative to AcMNPV-infected S. frugiperda SF9 cells viral DNA replication was severely reduced in Spodoptera littoralis SL2 cells. Microscopic examination of SL2-infected cells revealed progressive cell blebbing starting at 6-8 hr postinfection and culminating in total cell destruction at 24 hr postinfection. The data suggested that AcMNPV-infected SL2 cells undergo apoptosis. The occurrence of an active apoptotic process in the infected cells was confirmed by: (1) observation of fragmentation of the cell nuclei stained with the specific fluorescent dye DAPI (4',6'-diamidino- 2-phenylindole) and (2) the presence of low-molecular-weight DNA oligomers. Neither SL2 cells infected with S. littoralis nuclear polyhedrosis virus (SINPV) nor SF9 cells infected with AcMNPV, respectively, showed nuclear fragmentation or oligonucleosomal ladder formation.
