A baculovirus vector derived from immediately early gene promoter of Autographa californica nuclear polyhedrosis virus.
A transfer vector was constructed in which the neomycin resistance (neo) gene was under the control of a copy of Autographa californica nuclear polyhedrosis virus (AcMNPV) IE1 gene promoter at the p10 locus. After cotransfection of Spodoptera frugiperda (Sf9) cells with the transfer vector and infectious AcMNPV DNA, the recombinant virus-containing neo gene was selected by serial passage of the...
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 کاملCytoplasmic Polyhedrosis Virus of Bombyx mori
Two structurally different classes of oligonucleotides accumulate in vitro in cytoplasmic polyhedrosis virus (CPV) transcription mixtures in molar excess as compared to the completed RNA products. The first class consists of oligonucleotides which correspond to the 5’terminal sequence of the virus mRNAs (referred to as initiator oligonucleotides). The major species of initiator oligonucleotides...
متن کاملTranscriptome analysis of interactions between silkworm and cytoplasmic polyhedrosis virus
Bombyx mori cytoplasmic polyhedrosis virus (BmCPV) specifically infects silkworm midgut (MG) and multiplication occurs mainly in posterior midgut (PM). In this study, MG and fat body (FB) were extracted at 0, 3, 24, and 72 h after BmCPV infection. The total sequence reads of each sample were more than 1510000, and the mapping ratio exceeded 95.3%. Upregulated transcripts increased in MG during ...
متن کاملCharacterization of nuclear polyhedrosis virus DNAs.
The nuclear polyhedrosis virus DNAs characterized and compared in this study consist of the singly-enveloped nucleocapsids (SNPV) of Trichoplusia ni and the bundles of nucleocapsids common to a single envelope (MNPV) from Spodoptera frugiperda and Rachiplusia ou. The SNPV and MNPV DNAs are very similar in hydrodynamic properties and molecular weights. In addition, the NPV DNAs are similar in si...
