Recent evidence from genome sequence analyses demands a substantial revision of the taxonomy and classification of the family Baculoviridae. Comparisons of 29 baculovirus genomes indicated that baculovirus phylogeny followed the classification of the hosts more closely than morphological traits that have previously been used for classification of this virus(More)
Autographa californica multicapsid nucleopolyhedrovirus (AcMNPV) is the best-studied baculovirus and most commonly used virus vector for baculovirus expression vector systems. The effect of AcMNPV infection on host cells is incompletely understood. A microarray based on Spodoptera frugiperda ESTs was used to investigate the impact of AcMNPV on host gene(More)
The gp37 genes of the Mamestra brassicae and Lymantria dispar multicapsid nucleopolyhedroviruses (MbMNPV and LdMNPV) have been identified and characterized. Both genes were similar to other baculovirus gp37 genes and to entomopoxvirus fusolin genes. Phylogenetic analysis showed that baculovirus gp37 genes and entomopoxvirus fusolin genes form two distinct(More)
A physical map of Anagrapha falcifera multinucleocapsid nuclear polyhedrosis virus (AfMNPV) DNA was constructed for restriction endonucleases EcoRI, HindIII, PstI and XhoI. The genome size was estimated to be 130 kbp. Ordering of the restriction fragments was accomplished by cross-blot hybridization, double digestion and DNA-DNA hybridization. The(More)
beta- and gamma-nonmuscle actins differ by 4 amino acids at or near the N terminus and distant from polymerization interfaces. beta-Actin contains an Asp(1)-Asp(2)-Asp(3) and Val(10) whereas gamma-actin has a Glu(1)-Glu(2)-Glu(3) and Ile(10). Despite these small changes, conserved across mammals, fish, and birds, their differential localization in the same(More)
An Autographa californica nuclear polyhedrosis virus gene encoding a 30-kilodalton polypeptide with two different sequence motifs characteristic of DNA-binding proteins was identified immediately downstream of the major capsid protein gene (vp39). The gene, CG30, was characterized by sequencing, transcriptional mapping, in vitro translation of(More)
The gene encoding the major capsid protein of the baculovirus Autographa californica nuclear polyhedrosis virus (AcMNPV) was identified, sequenced, and transcriptionally mapped. The location of the gene was determined by immunological screening of an expression library of AcMNPV open reading frame-beta-galactosidase fusions with an antibody raised to virus(More)
A gene that promotes Autographa californica M nuclear polyhedrosis virus (AcMNPV) replication in IPLB-Ld652Y cells, a cell line that is nonpermissive for AcMNPV, was identified in Lymantria dispar M nuclear polyhedrosis virus (LdMNPV). Cotransfection of AcMNPV DNA and a plasmid carrying the LdMNPV gene into IPLB-Ld652Y cells results in AcMNPV replication.(More)
Protein synthesis is globally shut down at late times postinfection in the baculovirus Autographa californica M nuclear polyhedrosis virus (AcMNPV)-infected gypsy moth cell line Ld652Y. A single gene, hrf-1, from another baculovirus, Lymantria dispar M nucleopolyhedrovirus, is able to preclude protein synthesis shutdown and ensure production of AcMNPV(More)
