Eragrovirus
Eragrovirus is a genus of viruses, in the family Geminiviridae. Dicotyledonous plants serve as natural hosts. There is currently only one species in this genus: the type species Eragrostis curvula streak virus.[1][2]

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 |
gollark: I can mostly only think of food and water as immediately problematic things, and it's still a lot easier to import help when on the ground.
gollark: Terrestrial housing gets breathable air and some degree of temperature control "for free".
gollark: It'll probably be a while before there are actually space habitats that big, and more having to be done technologically probably means more failures.
gollark: If they fail on a space habitat, I probably die horribly and can't easily get help from somewhere nearby.
gollark: If the power or water supply fail here, I'll probably be somewhat uncomfortable until they're restored, but be basically fine, at least as long as they're available somewhere not too far away.
