Identification of a novel apoptosis suppressor gene from the baculovirus Lymantria dispar multicapsid nucleopolyhedrovirus.
Ld652Y cells from Lymantria dispar readily undergo apoptosis upon infection with a variety of nucleopolyhedroviruses (NPVs), while L. dispar multicapsid NPV (LdMNPV) infection of Ld652Y cells results in the production of a high titer of progeny viruses. Here, we identify a novel LdMNPV apoptosis suppressor gene, apsup, which functions to suppress apoptosis induced in Ld652Y cells by infection w...
متن کاملCharacterization of the Lymantria dispar nucleopolyhedrovirus 25K FP gene.
The Lymantria dispar nucleopolyhedrovirus (LdMNPV) gene encoding the 25K FP protein has been cloned and sequenced. The 25K FP gene codes for a 217 amino acid protein with a predicted molecular mass of 24870 Da. Expression of the 25K FP protein in a rabbit reticulocyte system generated a 27 kDa protein, in close agreement with the molecular mass predicted from the nucleotide sequence. The gene i...
متن کاملIdentification of a novel Lymantria dispar nucleopolyhedrovirus mutant that exhibits abnormal polyhedron formation and virion occlusion.
In previous studies on the formation of Lymantria dispar nuclear polyhedrosis virus (LdMNPV) few polyhedra (FP) mutants, several polyhedron formation mutants (PFM) were identified that appeared to be unique. These viral mutants are being characterized to investigate the processes of polyhedron formation and virion occlusion. LdMNPV isolate PFM-1 is one of these mutants, and is described in this...
متن کاملLymantria dispar nucleopolyhedrovirus hrf-1 expands the larval host range of Autographa californica nucleopolyhedrovirus.
The gypsy moth (Lymantria dispar) is nonpermissive for Autographa californica nucleopolyhedrovirus (AcNPV) infection. We previously isolated a gene, host range factor 1 (hrf-1), from L. dispar nucleopolyhedrovirus that promotes AcNPV replication in Ld652Y cells, a nonpermissive L. dispar cell line (S. M. Thiem, X. Du, M. E. Quentin, and M. M. Berner, J. Virol. 70:2221-2229, 1996). In the presen...
متن کاملBoth Lymantria dispar nucleopolyhedrovirus enhancin genes contribute to viral potency.
Enhancins are a group of proteins first identified in granuloviruses (GV) that have the ability to enhance nuclear polyhedrosis virus potency. We had previously identified an enhancin gene (E1) in the Lymantria dispar multinucleocapsid nucleopolyhedrovirus (LdMNPV) (D. S. Bischoff and J. M. Slavicek, J. Virol. 71:8133-8140, 1997). Inactivation of the E1 gene product within the viral genome lowe...
