Mimoreovirus
Genus of viruses
From Wikipedia, the free encyclopedia
Mimoreovirus is a genus of viruses, in the family Sedoreoviridae. The only isolate infects the marine photosynthetic protist Micromonas pusilla, a prasinophyte.[1] There is only one species in this genus: Micromonas pusilla reovirus (Mimoreovirus micromonadis).[2][3][4]

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.[2]

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.[2]
