Pecluvirus is a genus of viruses, in the family Virgaviridae . [2] Cereal crops and graminaceous weeds serve as natural hosts. There are two species in this genus. Diseases associated with this genus include: (SBWMV): green and yellow mosaic. [2] [3] [4] The name of the genus is derived from Peanut clump virus: Peanut clump virus, giving rise to Pecluvirus.

Taxonomy

The following two species are assigned to the genus: [4]

Structure

Viruses in the genus Pecluvirus are non-enveloped, with elongated rod-shaped geometries, and helical symmetry. The diameter is around 21 nm, with a length of 245 nm. Genomes are linear and segmented, segments are about 5.9 and 4.8kb in length. [2] [3]

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, and suppression of termination. The virus exits the host cell by tripartite non-tubule guided viral movement. Cereal crops and graminaceous weeds serve as the natural host. The virus is transmitted via a vector (fungus). Transmission routes are vector and seed borne. [2] [3]

<i>Crinivirus</i> Genus of viruses

Crinivirus, formerly the lettuce infectious yellows virus group, is a genus of viruses, in the family Closteroviridae. They are linear, single-stranded positive sense RNA viruses. There are 14 species in this genus. Diseases associated with this genus include: yellowing and necrosis, particularly affecting the phloem.

Luteovirus is a genus of viruses, in the family Tombusviridae. There are 13 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. 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.
