Taxonomy
Group: dsRNA
Structure
Viruses in Idnoreovirus are non-enveloped, with icosahedral geometries, and T=13, T=2 symmetry. The diameter is around 70 nm. Genomesare linear and segmented, around 480027-30kb in length. The genome codes for 11 proteins.
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment to host receptors, which mediates endocytosis. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. The virus exits the host cell by monopartite non-tubule guided viral movement. Hymonoptera insects serve as the natural host.
