Virus classification
Group: Group IV ((+)ssRNA)
Family: Closteroviridae
Genus: Crinivirus
Species: Potato yellow vein virus

The Potato yellow vein virus (PYVV) is a plant pathogen of the Closteroviridae family. It is a whitefly-transmitted closterovirus vectored by Trialeurodes vaporariorum, which is known to cause a yellowing disease in potato crops in South America.[1]

PYVV RNA have a conserved 3'-terminal secondary structure, which includes a pseudoknot.[1]
