::summary Genus of viruses ::

| taxon = Luteovirus

Luteovirus is a genus of viruses, in the family Tombusviridae. There are 14 species in this genus. Plants serve as natural hosts. The geographical distribution of Luteoviruses is widespread, with the virus primarily infecting plants via transmission by aphid vectors. The virus only replicates within the host cell and not within the vector https://web.archive.org/web/20010219050554/http://www4.ncbi.nlm.nih.gov/ICTVdb/ICTVdB/39010000.htm. The name 'luteovirus' arises from the Latin luteus, which is translated as 'yellow'. Luteovirus was given this name due to the symptomatic yellowing of the plant that occurs as a result of infection.

Taxonomy

The genus contains the following species, listed by scientific name and followed by their common names:

• Luteovirus avii, Cherry associated luteovirus

Morphology and genome structure

Viruses in Luteovirus are non-enveloped, with icosahedral and spherical geometries, and T=3 symmetry. The diameter is around 25-30 nm,

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 leaky scanning, -1 ribosomal frameshifting, and suppression of termination. The virus exits the host cell by tubule-guided viral movement. Plants serve as the natural host. The virus is transmitted via a vector (insects). Transmission routes are vector and mechanical.
