Tobacco mosaic virus [a] (TMV) is a positive-sense single-stranded RNA virus species in the genus Tobamovirus that infects a wide range of plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns, such as "mosaic"-like mottling and discoloration on the leaves (hence the name).
[3] [4] The name Tobamovirus comes from the host and symptoms of the first virus discovered (Tobacco mosaic virus). [ 5 ] There are four informal subgroups within this genus: these are the tobamoviruses that infect the brassicas , cucurbits , malvaceous , and solanaceous plants.
The trivial genome map of satellite virus genera Virtovirus and Aumaivirus [4] Tobacco virtovirus 1 is a small, icosahedral plant virus which worsens the symptoms of infection by Tobacco mosaic virus (TMV). Satellite viruses are some of the smallest possible reproducing units in nature; they achieve this by relying on both the host cell and a ...
[4] [5] Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, [6]: 4 more than 11,000 of the millions of virus species have been described in detail. [7] [8] The study of viruses is known as virology, a subspeciality of ...
Pepper mild mottle virus (PMMoV) is a plant pathogenic virus that occurs worldwide on species of field grown bell, hot and ornamental pepper species. It is caused by members of the plant virus genus Tobamovirus—otherwise known as the tobacco mosaic virus family. Tobamovirus are viruses that contain positive sense RNA genomes that infect ...

After tobacco mosaic was recognized as a virus disease, virus infections of many other plants were discovered. [34] The importance of tobacco mosaic virus in the history of viruses cannot be overstated. It was the first virus to be discovered, and the first to be crystallised and its structure shown in detail.
Transmission electron micrograph of Tobacco mosaic virus, the first virus to be discovered and a ribovirian. Diseases caused by viruses in Riboviria have been known for much of recorded history, though their cause was only discovered in modern times. Tobacco mosaic virus was discovered in 1898 and was the first virus to be discovered. [56]
