Role of the phosphatidylinositol-3-kinase/Akt/target of rapamycin pathway during ambidensovirus infection of insect cells.
TLDR
The deciphered the role of PI3K/Akt/TOR signalling in the course of infection and found that non-structural (NS) protein expression correlates with the inhibition of TOR and the shutdown of cellular synthesis, concomitant with the burst of viral protein expression. Expand
Characterization of a new densovirus infecting the German cockroach, Blattella germanica.
TLDR
A new DNA virus (Parvoviridae: Densovirinae, Densovirus) was isolated and purified from descendants of field-collected German cockroaches, Blattella germanica, revealing the presence of extended palindromes. Expand
A Densovirus of German Cockroach Blattella germanica: Detection, Nucleotide Sequence, and Genome Organization
TLDR
A new Blattella germanica densovirus (BgDNV, Parvoviridae: Densovirinae, Densovirus) was found and the genome structure was compared with that of other Parviviridae. Expand
Decrease in the expression level of the gene encoding the putative Bombyx mori bidensovirus receptor during virus infection
Bombyx mori bidensovirus (BmBDV) is a pathogen that replicates only in the midgut columnar cells of silkworms, causing fatal disease. Resistance to BmBDV, which does not depend on the viral dose, isExpand
Characterization and genome comparison of an Indian isolate of bidensovirus infecting the silkworm Bombyx mori
TLDR
The bipartite genome of an Indian isolate of Bombyx mori bidensovirus (BmBDV), one of the causative agents of the fatal silkworm disease ‘Flacherie’, was cloned and completely sequenced and revealed two viral DNA segments, VD1 and VD2 as well as a DNA polymerase motif which supports its taxonomical status as the type species of a new family of Bidnaviridae. Expand
Densovirus infection in silkworm Bombyx mori and genes associated with disease resistance
TLDR
While most of the strains of B. mori are susceptible to BmDV, few races have been found to be completely resistant to the virus, and the studies undertaken towards screening of B mDV resistant silkworm Races have been discussed in this review. Expand
Genetic engineering of Periplaneta fuliginosa densovirus as an improved biopesticide
TLDR
This is the first report showing the improvement of engineered densovirus for the potential application of biopesticide. Expand
Susceptibility and tissue specificity of Spodoptera frugiperda to Junonia coenia densovirus
TLDR
It is shown that Junonia coenia densovirus has great potential as a biological control agent against pests such as S. frugiperda or S. litura, and although JcDV can infect all three lepidopteran species, their susceptibility to the virus differs. Expand
Mass mortality in freshwater mussels (Actinonaias pectorosa) in the Clinch River, USA, linked to a novel densovirus
TLDR
Viral infection warrants consideration as a factor in unionid mass mortality events either as a direct cause, an indirect consequence of physiological compromise, or a factor interacting with other biological and ecological stressors to precipitate mortality. Expand
Virome Variation during Sea Star Wasting Disease Progression in Pisaster ochraceus (Asteroidea, Echinodermata)
Sea star wasting disease (SSWD) is a condition that has affected asteroids for over 120 years, yet mechanistic understanding of this wasting etiology remains elusive. We investigated temporal viromeExpand

Biological and Molecular Properties of Densoviruses and Their Use in Protein Expression and Biological Control
The first report of an insect disease caused by a densovirus (DNV) goes back to the early 1960s when the Laboratoire de Pathologie Comparee, a reference center for diagnosis of invertebrate pathogensExpand
The structure of an insect parvovirus (Galleria mellonella densovirus) at 3.7 A resolution.
TLDR
The sequence of the glycine-rich motif, which occupies each of the channels along the fivefold axes in vertebrate viruses, is conserved between mammalian and insect parvoviruses. Expand
Detection of replicative intermediate with closed terminus of Bombyx densonucleosis virus
TLDR
The structure of the replicative intermediate of BmDNV DNAs is analyzed by CR using specific primers designed for detection of RI with closed terminal structure (RI-CT) which is expected to be formed by replication with self-priming mechanism, strongly suggested that the B mDNV-1 replicates with the “self-primed and hairpin-transfer” mechanism similar to the human parvoviruses, while Bm DNV-2 does not. Expand
Autonomous parvovirus and densovirus gene vectors.
TLDR
Results suggest that packaging LuIII transducing genomes into heterologous virions can effectively alter the specificity of transduction and may allow delivery of genes to a wider variety of cell types. Expand
Cryo-electron microscopy studies of empty capsids of human parvovirus B19 complexed with its cellular receptor.
TLDR
The three-dimensional structures of human parvovirus B19 VP2 capsids, alone and complexed with its cellular receptor, globoside, have been determined to 26 resolution and suggest that neutralization of virus infectivity is caused by preventing attachment of viruses to cells. Expand
DNA polymerase delta-dependent formation of a hairpin structure at the 5' terminal palindrome of the minute virus of mice genome.
TLDR
In an in vitro DNA replication system using HeLa cell extracts, it was found that there was a distinct activity that utilized the 5' terminal palindrome sequence of MVM to produce a secondary structure from a duplex extended form, in a time-dependent fashion. Expand
Testing the unique amplification event and the worldwide migration hypothesis of insecticide resistance genes with sequence data
TLDR
A surprisingly high level of nucleotide polymorphism is found in coding and noncoding regions, and the extent of polymorphism detected is higher than that previously described for the most polymorphic loci in Drosophila. Expand
The evolution and control of parvovirus host ranges
TLDR
Host ranges of parvoviruses are complex, and depend on both the strain of virus and on the cell or animal being inoculated, although differences in the non-structural protein genes of the minute virus of mice determine some host-range differences. Expand
Complete nucleotide sequence and genomic organization of the Aedes albopictus parvovirus (AaPV) pathogenic for Aedes aegypti larvae.
TLDR
Comparison with other invertebrate and vertebrate parvoviruses revealed that the AaPV genome shares 77.3% nt sequence homology and between 73 and 78% aa sequence homologies with the Aedes aegypti densonucleosis virus (Aedes DNV). Expand
Densovirus of Aedes aegypti as an expression vector in mosquito cells.
TLDR
The results indicate that the genome of AeDNV can serve as a vector for delivery and expression of foreign genes in mosquito cells with subsequent targeting of the product to the desired cell compartment. Expand
