|3'-terminal pseudoknot in BYV|
|Predicted secondary structure of the 3'-terminal pseudoknot in BYV|
Closterovirus, also known as beet yellows viral group, is a plant-infecting viral genus included in family Closteroviridae. This genus has a probably worldwide distribution and includes among other viral species the Beet yellows virus and the tentatively assigned Citrus tristeza virus, rather economically important plant diseases. At least some species require vectors such as aphids or mealybugs for their transmission from plant to plant.
The viral RNA molecules of some members of this genus contain four hair-pin structures and a pseudoknot in the 3'UTR. These secondary structures have been found to be important in viral RNA replication.
