The GP64 protein of Autographa californica multiple nucleopolyhedrovirus rescues Helicoverpa armigera nucleopolyhedrovirus transduction in mammalian cells

Journal of General Virology, 2005
Autographa californica multiple nucleopolyhedrovirus (AcMNPV) belonging to the group I nucleopolyhedroviruses (NPVs) and expressing the envelope-fusion glycoprotein GP64 transduces a variety of mammalian cells to express foreign genes under the control of mammalian promoters. In contrast, the group II Helicoverpa armigera single NPV (

Transgenic Clustered Regularly Interspaced Short Palindromic Repeat/Cas9-Mediated Viral Gene Targeting for Antiviral Therapy of Bombyx mori Nucleopolyhedrovirus

Journal of Virology, 2017
We developed a novel antiviral strategy by combining transposon-based transgenesis and the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9) system for the direct cleavage of Bombyx mori nucleopolyhedrovirus ...

RNAi Regulator C3PO Promotes Arbovirus Infection in Insect Vectors

Advanced Science, Volume 13, Issue 4, 19 January 2026.
RNA interference (RNAi) is vital for eukaryotes to defend against virus infection. The C3PO complex takes part in RNAi but its role in regulating viral infection remains unclear. This work finds that insect C3PO facilitates arbovirus replication by degrading precursors of miRNAs, especially miR‐971‐3p.

Specificity of Baculorivus P6.9 Basic DNA-Binding Proteins and Critical Role of the C Terminus in Virion Formation

, 2010
The majority of double-stranded DNA (dsDNA) viruses infecting eukaryotic organisms use host- or virus-expressed histones or protamine-like proteins to condense their genomes.

Characterization of Bombyx mori nucleopolyhedrovirus with a knockout of Bm17 [PDF]

Cytotechnology, 2012
Open reading frame 17 (Bm17) gene of Bombyx mori nucleopolyhedrovirus is a highly conserved gene in lepidopteran nucleopolyhedroviruses, but its function remains unknown. In this report, transient-expression and superinfection assays indicated that BM17 localized in the nucleus and cytoplasm of infected BmN cells.

Functional analysis of FP25K of Helicoverpa armigera single nucleocapsid nucleopolyhedrovirus

, 2005
The fp25k gene of Helicoverpa armigera single nucleocapsid nucleopolyhedrovirus (HearNPV) was studied. HearNPV fp25k gene transcription was found starting from about 18 h post-infection, and protein could be detected from the same time with antiserum ...

A Role for the Anti-Viral Host Defense Mechanism in the Phylogenetic Divergence in Baculovirus Evolution. [PDF]

PLoS ONE, 2016
Although phylogenic analysis often suggests co-evolutionary relationships between viruses and host organisms, few examples have been reported at the microevolutionary level. Here, we show a possible example in which a species-specific anti-viral response

Update of the list of QPS‐recommended biological agents intentionally added to food or feeds as notified to EFSA

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The qualified presumption of safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of relevant knowledge and safety concerns of microorganisms intentionally added to the food and feed chain.
