Becurtovirus is a genus of viruses, in the family Geminiviridae. Dicotyledonous plants serve as natural hosts. There are currently only two species in this genus, including the type species Beet curly top Iran virus.[1][2]
Taxonomy
Group: ssDNA
Order: Unassigned
- Family: Geminiviridae
- Genus: Becurtovirus
- Beet curly top Iran virus
- Spinach curly top Arizona virus
Structure
Viruses in Becurtovirus are non-enveloped, with icosahedral geometries, and T=1 symmetry. Genomes are circular and non-segmented, around 3.0kb in length.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Becurtovirus | Twinned Icosahedral | Incomplete T=1 | Non-enveloped | Circular | Monopartite |
Life cycle
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. Dicotyledonous plants serve as the natural host.[1]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Becurtovirus | Spinach | Phloem; sieve; phloem-limited | Viral movement; mechanical inoculation | Budding | Nucleus | Nucleus | Viral movement; contact |
