Abstract Densoviruses continues to increase and, as a group, to diversify. Based on recent data on the structure and organization of their genome, we propose here a taxonomic structure for the Densovirinae subfamily including four genera instead of the three adopted recently by the ICTV. One putative genus,Bidensovirus, is proposed for densoviruses with a bipartite genome which replicate differently from other parvoviruses. A working model of their replication fitting the characteristics of the… Expand
Parvoviruses of Arthropods
Densoviruses (DNVs) are small icosahedral nonenveloped parvoviruses of arthropods containing a single-stranded linear genome 4–6 kb in length. They are classified, along with their vertebrateExpand
Effects of recombination on densovirus phylogeny
The aim of the present work was to study possible recombination events in the evolutionary history of densoviruses and to assess possible effects of recombination on phylogenies inferred using amino acid sequences of nonstructural (NS) and capsid (viral protein, VP) proteins. Expand
The structure of an insect parvovirus (Galleria mellonella densovirus) at 3.7 A resolution.
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
Genome organization of Casphalia extranea densovirus, a new iteravirus.
The approximate 75% sequence identity between the DNAs from CeD NV and BmDNV-1 and identical genome organization indicated that CeDNV should be classified in the Iteravirus genus. Expand

The sudden and devastating emergence of mink enteritis virus (MEV) and CPV in the last 50 years, and the possibility of more future outbreaks, demonstrates the importance of understanding parvovirus tropism. Expand
Transcription of the German cockroach densovirus BgDNV genome: Alternative processing of viral RNAs
It was shown that splicing of RNAs encoding both VP and NS proteins is observed during infection development and that the viral RNAs for NS proteins undergo alternative splicing, and the size of the transcripts synthesized from two viral promoters were determined. Expand
Organization and Expression Strategy of the Ambisense Genome of Densonucleosis Virus of Galleria mellonella
Despite the transcription and translation strategies being radically different from those of vertebrate parvoviruses, the capsid was found to have phospholipase A2 activity, a feature thus far unique for parviviruses. Expand
Genome organization of the densovirus from Bombyx mori (BmDNV-1) and enzyme activity of its capsid.
It is demonstrated that capsids have a phospholipase A2 activity thus far unknown to occur in viruses, which showed a substrate preference for phosphatidylethanolamine andosphatidylcholine over phosph atidylinositol. Expand
Novel parvoviruses in reptiles and genome sequence of a lizard parvovirus shed light on Dependoparvovirus genus evolution.
The suspected ability for autonomous replication, results of phylogenetic tree reconstruction, intron lengths and the structure of the AAP suggested that a single Squamata origin instead of the earlier assumed diapsid (common avian-reptilian) origin is more likely for the genus Dependoparvovirus of the family Parvoviridae.
