Spinareovirinae ''Spinareovirinae'' is a subfamily of double-stranded RNA viruses in the family ''Reoviridae''. Viruses in this group are distinguished by the presence of a turreted protein on the inner capsid. (''Spina'' = spiny or thorny in Latin.) Taxonomy ...

Hymenoptera Hymenoptera is a large order (biology), order of insects, comprising the sawfly, sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are Par ...

Structure

Viruses in genus ''Idnoreovirus'' are non-enveloped, with icosahedral geometries. The outer capsid has T=13 symmetry and the inner capsid has T=2 symmetry. The diameter is around 70 nm. Genomes are linear and segmented. They are around 27–30 kbp in total 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.
