Cheravirus is a genus of viruses in the order Picornavirales , in the family Secoviridae . Plants serve as natural hosts. There are eight species in this genus. [1] [2] [3]
The name is derived from Cherry rasp leaf virus.
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species: [2] [4]
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]

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]
