Foveavirus is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants serve as natural hosts. There are 13 species in this genus. Diseases associated with this genus include: mosaic and ringspot symptoms.[1][2]

Taxonomy

The following species are assigned to the genus, listed by scientific name and followed by the exemplar virus of the species:[2]

Structure

Viruses in Foveavirus are non-enveloped, with flexuous and filamentous geometries. The diameter is around 12-13 nm. Genomes are linear, around 8.4-9.3kb in length. The genome codes for 5 proteins.[1]

Life cycle

Viral replication is cytoplasmic, and is lysogenic. 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 tripartite non-tubule guided viral movement. Plants serve as the natural host. Transmission routes are grafting.[1]
