(unranked): Virus
Realm: Monodnaviria
Kingdom: Shotokuvirae
Phylum: Cossaviricota
Class: Quintoviricetes
Order: Piccovirales
Family: Parvoviridae
Subfamily: Densovirinae
Genus: Iteradensovirus

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]

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]
