''Macluravirus'' is a genus of
viruses
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Viruses are found in almo ...

Description
''Macluravirus'' is characterised by its flexuous filamentous particles,
inclusion bodies
Inclusion bodies are aggregates of specific types of protein found in neurons, and a number of tissue (biology), tissue cells including red blood cells, bacteria, viruses, and plants. Inclusion bodies of aggregations of multiple proteins are also ...
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 member species
Maclura mosaic virus.
History
The genus was proposed at the ICTV meeting in San Diego in 1998, and subsequently ratified.
Structure
Viruses 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.
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 (insects). Transmission routes are vector and mechanical.
