Virus classification Edit this classification
(unranked): Virus
Realm: Riboviria
Kingdom: Orthornavirae
Phylum: Pisuviricota
Class: Pisoniviricetes
Order: Picornavirales
Family: Secoviridae
Genus: Cheravirus

Cheravirus is a genus of viruses in the order Picornavirales, in the family Secoviridae. Plants serve as natural hosts. There are five species in this genus.[1][2][3]

The name is derived from Cherry rasp leaf virus.

Taxonomy

The genus contains the following species:[2]

Structure

Viruses in Cheravirus are non-enveloped, with icosahedral geometries, and T=pseudo3 symmetry. The diameter is around 25-30 nm. Genomes are linear and bipartite, around 13.3kb in length.[1]

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 (nematodes maybe seed-transmitted). Transmission routes are vector and seed borne.[1]
