Gene coded for a polypeptide which enhances virus infection of host insects

摘要

Cloning and sequencing certain baculovirus genes encoding polypeptides termed enhancins. The polypeptides are isolated from the occlusion body of certain baculoviruses such as Trichoplusia ni granulosis virus and Pseudaletia unipuncta granulosis virus, Hawaiian strain. The polypeptides have the ability of enhancing the infectivity of baculoviruses and are useful ingredients of pest control compositions.
