Turncurtovirus
Genus of viruses
From Wikipedia, the free encyclopedia
Turncurtovirus 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
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:[2][3]
- Turncurtovirus brassicae, Turnip curly top virus
- Turncurtovirus rapae, Turnip leaf roll virus
- Turncurtovirus sesami, Sesame curly top virus
Structure
Viruses in Turncurtovirus 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 |
|---|---|---|---|---|---|
| Turncurtovirus | 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]
