Strawberry vein banding virus
Strawberry vein banding virus (SVBV) is a plant pathogenic virus and a member of the family Caulimoviridae. It was first described by Frazier after differential aphid transmission to susceptible wild strawberries. He identified suitable virus indicators and demonstrated virus transmission by various aphids, dodder, and grafting. He also established the inability of the virus to transmit via sap.
Stenger purified and cloned the SVBV genome. Due to the limited techniques of the time he was unable to demonstrate the infectious nature of the clone.
