Turncurtovirus


Turncurtovirus is a genus of viruses, in the family Geminiviridae. Dicotyledonous plants serve as natural hosts. There are three species in this genus.

Taxonomy

The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:Turncurtovirus brassicae, Turnip curly top virusTurncurtovirus rapae, Turnip leaf roll virusTurncurtovirus 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.

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.
