Tobacco mosaic virus (TMV) is an RNA virus that infects plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns (mottling and discoloration) on the leaves (thus the name).

The Tobacco mosaic virus (TMV) is an RNA virus that infects plants, especially tobacco, showing characteristic patterns (mottling and discoloration) on the leaves (thus the name). It was the first virus to be discovered.
Tomato plants infected with tobacco mosaic virus (which attacks tomato plants as well as tobacco). The plants in the back row carry an introduced gene conferring resistance to the virus.
" Russian biologist Dimitri Ivanowsky worked with tobacco mosaic virus. In 1892 he confirmed Pasteur's hypothesis of an infectious agent smaller than bacteria.
Viruses consist of a nucleic acid (DNA or RNA) enclosed in a protein coat (known as a capsid). The capsid may be a single protein repeated over and over, as in tobacco mosaic virus (TMV).
Very simple viruses like the tobacco mosaic viruses that infect tobacco leaves, are composed of RNA and a single type of protein.
