Babuvirus is a genus of virus in the Family Nanoviridae that lives in Africa and Asia. It targets plants and is responsible for many banana deaths of African farms. TheGenus Babuviruscontains two species.
Babuvirus's form of reproduction is termed by virologists "Nuclear". The virus first penetrates the membrane of its host plant cell, then uncoats and releases its ssDNA into the host cell's nucleus. Then the ssDNA is converted into dsDNA with the help of the host cell. This allows the virus's proteins to be read by the host cell's workers. After the virus's proteinswere converted, the host cell now makes the virusand releases them through its own membrane.
Babuvirusis transmitted by aphids from plant to plant.
Babuvirus is a genus of viruses, in the family Nanoviridae.[1] Musa species serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: stunting, severe necrosis and early plant death. BBTV induces banana bunchy top disease (BBTD).[1][2][3]
The following species are included in the genus:[3]
Viruses in the genus Babuvirus are non-enveloped, with icosahedral and round geometries, and T=1 symmetry. The diameter is around 18-19 nm.
Genomes are multipartite with 6 to 8 circular segments. Genome size is around 81 kb in totsl.[1][2]
Viral replication is nuclear. Entry into the host cell is achieved by penetration into the host cell. Replication follows the ssDNA rolling circle model. DNA templated transcription is the method of transcription. The virus exits the host cell by nuclear pore export, and tubule-guided viral movement. Musa species serve as the natural host. The virus is transmitted via a vector (aphids). Transmission routes are vector.[1][2]
