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...

Tobacco mosaic virus (TMV) is a positive-sense single stranded RNA virus that infects plants, namely tobacco and other members of the family Solanaceae. It causes characteristic patterns on the leaves. In 1930 it was determined that an infectious agent was determined to be a virus. Adolf Mayer first described the disease in 1883. The disease can be transferred between plants similar to...
