''. Plants serve as natural hosts. There are two species in this genus. Diseases associated with this genus include: TVCV: vein-clearing symptoms in ''N. edwardsonii''.
Taxonomy
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:
* ''Solendovirus venaipomeae'',
Sweet potato vein clearing virus
* ''Solendovirus venanicotianae'',
Tobacco vein clearing virus
Structure
Viruses in ''Solendovirus'' are non-enveloped, with icosahedral geometries, and T=7 symmetry. The diameter is around 50 nm. Genomes are circular and non-segmented, around 7.7kb in length. The genome has 3 open reading frames.

Life cycle
Viral replication is nuclear/cytoplasmic. Replication follows the dsDNA(RT) replication model. dsDNA(RT) transcription is the method of transcription. The virus exits the host cell by nuclear pore export, and tubule-guided viral movement. Plants serve as the natural host. Transmission routes are seed borne.[
