Iteradensovirus


Iteradensovirus is a genus of viruses in the subfamily Densovirinae of the family Parvoviridae. Insects serve as natural hosts. There are seven species in this genus.

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.

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.
