RESUMO

A transient transactivation assay system was used in combination with an overlapping Autographa californica nuclear polyhedrosis virus clone library to identify genes involved in late and very late baculovirus gene expression. We have identified three genes within the 33.8- to 43.4-map-unit region of the A. californica nuclear polyhedrosis virus genome which contribute to expression from promoters of the vp39 major capsid protein and polyhedrin genes. One of these three genes corresponds to the previously identified DNA polymerase gene, while the other two genes encode previously unidentified polypeptides of 59,418 and 8,706 Da. None of these genes were required for expression from the early etl promoter.
