The tobacco mosaic virus (TMV) was the first virus to be discovered. That is to say, it was the first to be known as a virus.
It is a single stranded RNA virus which infects many plants, especially tobacco and other members of the family Solanaceae. The infection causes "mosaic"-like discolouration on the leaves. Although it was known from the late 19th century that an infectious disease was damaging tobacco crops, it was not until 1930 that the infectious agent was known to be a virus.
