Mimoreovirus is a genus of viruses, in the family Reoviridae, in the subfamily Sedoreovirinae. Marine photosynthetic protists serve as natural hosts. There is currently only one species in this genus: the type species Micromonas pusilla reovirus.

Taxonomy
Group: dsRNA
Structure
Viruses in Mimoreovirus are non-enveloped, with icosahedral geometries, and T=13, T=2 symmetry. The diameter is around 90-95 nm. Genomes are linear and segmented, around 15.8kb 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. Marine photosynthetic protists serve as the natural host. Transmission routes are passive diffusion.
