tobacco mosaic virus

n.
An RNA virus that causes mosaic disease in tobacco and some other plants and is widely used in research in virology and genetics.

tobacco mosaic virus (TMV)

a rod shaped viral particle consisting of an RNA helix surrounded by a protein coat. The virus was the first to be purified and crystallized. It causes yellowing and mottling in the leaves of tobacco and other crops (e.g. tomato) which affects adversely the quality and quantity of crop produced
