Becurtovirus is a genus of viruses, in the family Geminiviridae. Dicotyledonous plants serve as natural hosts. There are three species in this genus.[1][2]
Taxonomy
[edit]The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:[2][3]
- Becurtovirus betae, Beet curly top Iran virus
- Becurtovirus exomis, Exomis microphylla associated virus
- Becurtovirus spinaciae, Spinach curly top Arizona virus
Structure
[edit]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
[edit]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 |
