Phenotypic and genetic analysis of Lymantria dispar nucleopolyhedrovirus few polyhedra mutants: mutations in the 25K FP gene may be caused by DNA replication errors.

Abstract excerpt

We previously demonstrated that polyhedron formation (PF) mutants arise at a high frequency during serial passage of the Lymantria dispar nucleopolyhedrovirus (LdMNPV) in the L. dispar 652Y cell line (J. M. Slavicek, N. Hayes-Plazolles, and M. E. Kelly, Biol. Control 5:251-261, 1995). Most of these PF mutants exhibited the traits of few polyhedra (FP) mutants; however, no large DNA insertions or deletions that...
