Analysis of the Choristoneura fumiferana nucleopolyhedrovirus genome.
The double-stranded DNA genome of Choristoneura fumiferana nucleopolyhedrovirus (CfMNPV) was sequenced and analysed in the context of other group I nucleopolyhedroviruses (NPVs). The genome consists of 129,593 bp with a G + C content of 50.1 mol%. A total of 146 open reading frames (ORFs) of greater than 150 bp, and with no or minimal overlap were identified. In addition, five homologous region...
متن کاملCharacterization of a baculovirus lacking the alkaline nuclease gene.
The Autographa californica multiple nucleocapsid nucleopolyhedrovirus (AcMNPV) alkaline nuclease (AN) associates with the baculovirus single-stranded DNA binding protein LEF-3 and possesses both a 5'-->3' exonuclease and an endonuclease activity. These activities are thought to be involved in DNA recombination and replication. To investigate the role of AN in AcMNPV replication, the lambda Red ...
متن کاملCharacterization of late gene expression factors lef-9 and lef-8 from Bombyx mori nucleopolyhedrovirus.
Late gene expression factors, LEF-4, LEF-8, LEF-9 and P47 constitute the primary components of the Autographa californica multinucleocapsid polyhedrovirus (AcMNPV)-encoded RNA polymerase, which initiates transcription from late and very late promoters. Here, characterization of lef-9 and lef-8, which encode their corresponding counterparts, from Bombyx mori NPV is reported. Transcription of lef...
متن کاملChoristoneura fumiferana nucleopolyhedrovirus encodes a functional 3'-5' exonuclease.
The Choristoneura fumiferana nucleopolyhedrovirus (CfMNPV) encodes an ORF homologous to type III 3'-5' exonucleases. The CfMNPV v-trex ORF was cloned into the Bac-to-Bac baculovirus expression-vector system, expressed in insect Sf21 cells with an N-terminal His tag and purified to homogeneity by using Ni-NTA affinity chromatography. Biochemical characterization of the purified V-TREX confirmed ...
متن کاملBaculovirus DNA replication-specific expression factors trigger apoptosis and shutoff of host protein synthesis during infection.
Apoptosis is an important antivirus defense. To define the poorly understood pathways by which invertebrates respond to viruses by inducing apoptosis, we have identified replication events that trigger apoptosis in baculovirus-infected cells. We used RNA silencing to ablate factors required for multiplication of Autographa californica multicapsid nucleopolyhedrovirus (AcMNPV). Transfection with...
