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]

| Babuvirus | Icosahedral | T=1 | Non-enveloped | Circular | Segmented |
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]

Geminiviridae is a family of plant viruses that encode their genetic information on a circular genome of single-stranded (ss) DNA. There are 520 species in this family, assigned to 14 genera. Diseases associated with this family include: bright yellow mosaic, yellow mosaic, yellow mottle, leaf curling, stunting, streaks, reduced yields. They have single-stranded circular DNA genomes encoding genes that diverge in both directions from a virion strand origin of replication. According to the Baltimore classification they are considered class II viruses. It is the largest known family of single stranded DNA viruses.
Nanoviridae is a family of viruses. Plants serve as natural hosts. There are currently 12 species in this family, divided among 2 genera and one unassigned species. Diseases associated with this family include: stunting. Their name is derived from the Greek word νᾶνος, because of their small genome and their stunting effect on infected plants.
Avihepadnavirus is a genus of viruses, in the family Hepadnaviridae. Birds serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: hepatitis, hepatocellular carcinomas, and cirrhosis.
Betaflexiviridae is a family of viruses in the order Tymovirales. Plants and fungi serve as natural hosts. There are 108 species in this family, assigned to 13 genera in two subfamilies. Diseases associated with this family include mosaic and ringspot symptoms.

Diseases associated with this genus include: CSSV: leaf chlorosis, root necrosis, red vein banding in young leaves, small mottled pods, and stem/root swelling followed by die-back. Infection decreases yield by 25% within one year, 50% within two years and usually kills trees within 3–4 years.
Caulimovirus is a genus of viruses, in the family Caulimoviridae order Ortervirales. Plants serve as natural hosts. There are 12 species in this genus. Diseases associated with this genus include: vein-clearing or banding mosaic.
