Potato yellow vein virus
Encyclopedia
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

Pseudoknot
A pseudoknot is a nucleic acid secondary structure containing at least two stem-loop structures in which half of one stem is intercalated between the two halves of another stem. The pseudoknot was first recognized in the turnip yellow mosaic virus in 1982...
