}} Not to be confused with MaculavirusMacluravirus is a genus of viruses, in the family Potyviridae. Plants serve as natural hosts. There are currently six species in this genus including the type species Maclura mosaic virus.[1][2] TaxonomyGroup: ssRNA(+){{Collapsible list|title= Order: Unassigned|1={{Collapsible list| framestyle=border:none; padding:1.0em;|title=Family: Potyviridae |1={{hidden begin|title=Genus: Macluravirus}}
}} }}[2] DescriptionSimilarly to other Potyviridae genera, Macluravirus is characterised by its flexuous filamentous particles, inclusion bodies in infected plant cells and a polyprotein genome strategy. Unlike the other genera it is transmitted by insects. It also has shorter particles (650-660 nm in length). The genomes are monopartite. The name is derived from the type species, Maclura mosaic virus.[3] HistoryThe genus was proposed at the ICTV meeting in San Diego in 1998,[4] and subsequently ratified.[5] StructureViruses in Macluravirus are non-enveloped, with flexuous and Filamentous geometries. The diameter is around 12-15 nm, with a length of 650-660 nm. Genomes are linear and non-segmented, bipartite, around 8.0kb in length.[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. The virus is transmitted via a vector (insects). Transmission routes are vector and mechanical.[1]
