Tritimovirus


Tritimovirus is a genus of viruses, in the family Potyviridae. Plants serve as natural hosts. There are six species in this genus.

Taxonomy

The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:Tritimovirus arrhenatheri, Tall oatgrass mosaic virusTritimovirus avenae, Oat necrotic mottle virusTritimovirus bromi, Brome streak mosaic virusTritimovirus eqlidense, Wheat Eqlid mosaic virusTritimovirus triseti, Yellow oat-grass mosaic virusTritimovirus tritici, Wheat streak mosaic virus

Structure

Viruses in Tritimovirus are non-enveloped, with flexuous and filamentous geometries. The diameter is around 12-15 nm, with a length of 690-700 nm. Genomes are linear, monopartite or bipartite, and around 9.3-10.0kb in length.

Life cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement. Plants serve as the natural host. The virus is transmitted via a vector. Transmission routes are vector and mechanical.
