''Macanavirus'' 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.

''Tombusviridae'' is a family of single-stranded positive sense RNA plant viruses. There are three subfamilies, 17 genera, and 95 species in this family. The name is derived from ''Tomato bushy stunt virus'' (TBSV).

''. Plants serve as natural hosts. There is only one species in this genus: ''Furcraea necrotic streak virus''. Diseases associated with this genus include: macana disease.
Structure
Viruses in ''Macanavirus'' are non-enveloped, with icosahedral and spherical geometries, and T=3 symmetry. The diameter is around 28 nm. Genomes are linear, around 4kb 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, using the premature termination model of subgenomic RNA transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement. Plants serve as the natural host.[
