Abstract
Summary Synthesis of the polypeptides induced in CIV-infected cells was studied using radiolabelled methionine in a permissive cell line ofChoristoneura fumiferana. Analysis of labelled cell extracts by high resolution polyacrylamide gel electrophoresis (PAGE) revealed the sequential appearance of at least 28 structural and non-structural polypeptides in permissive conditions. This was confirmed by analysis of protein synthesis in non-permissive cell lines ofLymantria dispar, Aedes albopictus or by the use of protein, RNA and DNA synthesis inhibitors in the permissive cell line.
