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[edit | edit source]

The taxonomy of the Petuvirus genus is as follows:

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

Structure[edit | edit source]

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[edit | edit source]

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[edit | edit source]

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