Petuvirus

Petuvirus is a genus of viruses in the order Picornavirales, in the family Secoviridae, and in the subfamily Comovirinae. There is currently only one species in this genus: the Peanut stunt virus.

Taxonomy

The taxonomy of the Petuvirus genus is as follows:

• Order: Picornavirales
• Family: Secoviridae
• Subfamily: Comovirinae
• Genus: Petuvirus
• Species: Peanut stunt virus

Structure

Viruses in Petuvirus are non-enveloped, with icosahedral and spherical geometries, and T=pseudo3 symmetry. The diameter is around 28-30 nm. Genomes are linear and non-segmented, around 8.3-8.5kb in length.

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. 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.

Clinical

The Peanut stunt virus, the only species in the Petuvirus genus, causes significant disease in peanuts, leading to stunted growth and reduced yield.
