Abstract

The efficiency of replication of a cytoplasmic polyhedrosis virus isolated from a member of the order Lepidoptera, Euxoa scandens, was studied in eight different lepidopterean cell lines. Lymantria dispar cells, which were found to support viral replication, more efficiently, were used to follow the kinetics of appearance of viral-specific polypeptides by a 2-h pulse with [35S]methionine. Five polypeptides (ca. 120,000 molecular weight [120K], 105K, 66K, 46K, and 28K) were identified as components of the polyhedral inclusion bodies, and two polypeptides (112K and 39K) were assigned as viral-particle polypeptides. All these polypeptides were present after 24 h and were still being produced 96 h after infection. The rate of synthesis of the major polyhedral polypeptide (28K) increased in the time course of infection, whereas the background of cellular polypeptides seemed to be unaffected. An indirect immunoperoxidase technique, after sodium dodecyl sulfate-polyacrylamide gel electrophoresis was blotted to a nitrocellulose membrane, showed that traces of the major polyhedral polypeptide were found from 8 h postinfection.
