Gene coding for a polypeptide which enhances virus infection of host insects.

摘要

Isolated and cloned baculovirus genes encoding a polypeptide protein present in the occlusion body of certain baculoviruses such as Trichoplusia ni granulosis virus and Pseudaletia unipuncta granulosis virus Hawaiian strain, said genes possessing a biological activity of enhancing virus infection of host insects by causing rapid degradation of the peritrophic membrane lining the midgut lumen of insects. The invention is also directed to pesticides incorporating said genes, i.e. the purified conserved and enhancing baculovirus proteins herein termed enhancins.
