Luteoviridae

provided by wikipedia EN

Luteoviridae is a family of viruses. Plants serve as natural hosts. There are currently 33 species in this family, divided among 3 genera. Diseases associated with this family include: yellowing symptoms.[1][2]

Taxonomy

Group: ssRNA(+)

[2]

Structure

Viruses in Luteoviridae are non-enveloped, with icosahedral and Spherical geometries, and T=3 symmetry. The diameter is around 25-30 nm. Genomes are linear and non-segmented, around 5.3-5.7kb in length.[1] Luteoviruses can act as helper viruses for Umbraviruses, providing them with a coat protein.[2]

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.[1]
