Taxonomy

Group: ssRNA(+)

Structure

Viruses in Tobravirus are non-enveloped, with rod-shaped geometries, and helical symmetry. The diameter is around 22 nm, with two lengths: 46-115 nm and 180–215 nm. Genomes are linear and segmented, bipartite, positive-sense, single-stranded RNA around 26.84.5kb in total length (8600–11300 nucleotides for each length).

Life Cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. Translation takes place by suppression of termination. The virus exits the host cell by monopartite non-tubule guided viral movement. Plants serve as the natural host. The virus is transmitted via a vector (mechanical nematodes trichodorus and paratrichodorus). Transmission routes are vector and mechanical.
