Time Course Analysis and Mapping of Autographa californica Nuclear Polyhedrosis Virus Transcripts.
To study the expression of the Autographa californica nuclear polyhedrosis virus (AcNPV) genome, intracellular virus-specific proteins and mRNAs were pulsed-labeled, extracted, and analyzed at 6-h intervals during the replicative cycle. Most RNAs were detected between 12 and 24 h postinfection (p.i.), but many continued to be synthesized until late in infection. Polyhedrin and p8 mRNAs were the...
متن کاملIdentifying the RNA polymerases that synthesize specific transcripts of the Autographa californica nuclear polyhedrosis virus.
Nuclear run-on assays carried out in the presence and absence of the RNA polymerase II inhibitor, alpha-amanitin, were used to determine the exact timing of the switch from inhibitor-sensitive transcription catalysed by host RNA polymerase II, to inhibitor-resistant transcription catalysed by the baculovirus-induced RNA polymerase. These studies revealed that the onset of alpha-amanitin-resista...
متن کاملAnalysis of the promoter of the Autographa californica nuclear polyhedrosis virus p10 gene.
Functional analyses of the p10 gene promoter from the Autographa californica nuclear polyhedrosis virus (AcNPV) were performed by progressively deleting the 230 nucleotides upstream from the p10 coding sequences towards the ATG codon. Truncated promoter sequences retaining the full 5' non-coding leader of p10 were inserted in front of the chloramphenicol acetyltransferase (CAT) gene, and promot...
متن کاملAutographa californica nuclear polyhedrosis virus DNA polymerase: measurements of processivity and strand displacement.
The DNA polymerase (DNApol) of Autographa californica nuclear polyhedrosis virus was purified to homogeneity from recombinant baculovirus-infected cells. DNApol was active in polymerase assays on singly primed M13 template, and full-length replicative form II product was synthesized at equimolar ratios of enzyme to template. The purified recombinant DNApol was shown to be processive by template...
متن کاملEffects of Temperature and pH on Survival of Free Nuclear Polyhedrosis Virus of Autographa californica.
The effects of temperature and low pH on replication and survival of nonoccluded Autographa californica nuclear polyhedrosis virus were investigated. No virus replication or formation of polynuclear inclusion bodies occurred at 37 degrees C. The virus was immediately inactivated upon exposure to pH 2.0 and was inactivated within 1 h at pH 4.0. The virus titer slowly declined, a 3-orders of magn...
