Vitivirus is a genus of

viruses in the order Tymovirales, in the family Betaflexiviridae.[1][2] Plants serve as natural hosts. There are 15 species in this genus.[1][3]

Taxonomy

The genus contains the following species:[1]

Structure

Viruses in Vitivirus are non-enveloped, with flexuous and filamentous geometries. The diameter is around 12 nm. Genomes are linear, around 7.6kb in length. The genome codes for 5 proteins.[3]

Vitivirus Filamentous Non-enveloped Linear Monopartite

Life cycle

Viral replication is cytoplasmic, and is lysogenic. 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. The virus exits the host cell by tubule-guided viral movement. Plants serve as the natural host. The virus is transmitted via a vector (mechanical inoculation pseudococcid mealybugs and

aphids). Transmission routes are vector and mechanical.[3]
