Biology:Eragrovirus
Eragrovirus is a genus of viruses, in the family Geminiviridae. Dicotyledonous plants serve as natural hosts. There is only one species in this genus: Eragrostis curvula streak virus (Eragrovirus curvulae).[1][2][3]
Structure
Viruses in Eragrovirus 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 |
|---|---|---|---|---|---|
| Eragrovirus | 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 |
|---|---|---|---|---|---|---|---|
| Eragrovirus | Plants | None | Viral movement; mechanical inoculation | Budding | Nucleus | Nucleus | Treehopper; leafhopper |
