Iteradensovirus is a genus of viruses in the subfamily Densovirinae[1] of the family Parvoviridae.[2][3] Insects serve as natural hosts. There are five species in this genus.[4][5]
Taxonomy
The following five species are assigned to the genus:[5]
- Lepidopteran iteradensovirus 1
- Lepidopteran iteradensovirus 2
- Lepidopteran iteradensovirus 3
- Lepidopteran iteradensovirus 4
- Lepidopteran iteradensovirus 5
Structure
Viruses in Iteradensovirus are non-enveloped, with icosahedral and Round geometries, and T=1 symmetry. The diameter is around 21-22 nm. Genomes are linear, around 5kb in length.[4]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
| Iteradensovirus | Icosahedral | T=1 | Non-enveloped | Linear | None |
Life cycle
Viral replication is nuclear. Entry into the host cell is achieved by attachment to host receptors, which mediates clathrin-mediated endocytosis. Replication follows the rolling-hairpin model. DNA templated transcription, with some alternative splicing mechanism is the method of transcription. Insects serve as the natural host.[4]
