}}Velarivirus is a genus of viruses, in the family Closteroviridae. Plants serve as natural hosts. There are currently three species in this genus, including the type species Grapevine leafroll-associated virus 7. Diseases associated with this genus include: GLRaV-7: symptomless in white-berried grapevine cultivar from Albania. However, it induces leafroll symptoms onto grafted cv. cabernet.[1][2] TaxonomyGroup: ssRNA(+){{Collapsible list|title= Order: Unassigned|1={{Collapsible list| framestyle=border:none; padding:1.0em;|title=Family: Closteroviridae |1={{hidden begin|title=Genus: Velarivirus}}
}} }}[2] StructureViruses in Velarivirus are non-enveloped, with filamentous geometries. These viruses are about 1500-1700 nm long. Genomes are linear, around 16-17kb in length. The genome codes for 10 proteins.[1]
Life cycleViral 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. Transmission routes are mechanical.[1]
