Tobacco mosaic virus has been known to cause a production loss for flue cured tobacco of up to two percent in North Carolina. [33] It is known to infect members of nine plant families, and at least 125 individual species, including tobacco, tomato , pepper (all members of the Solanaceae ), cucumbers , a number of ornamental flowers , [ 34 ] and ...
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 ...
The infection is localized to begin with but if the virus remains unchallenged it will spread via the vascular system into a systemic infection. The exact mechanism the virus uses to move throughout the plant is unknown but the interaction of pectin methylesterase , a cellular enzyme important for cell wall metabolism and plant development ...
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.
Notable plant viruses include the papaya ringspot virus, which has caused millions of dollars of damage to farmers in Hawaii and Southeast Asia, [36] and the tobacco mosaic virus which caused scientist Martinus Beijerinck to coin the term "virus" in 1898. [37] Bacterial plant pathogens cause leaf spots, blight, and rot in many plant species. [38]
A mosaic virus is any virus that causes infected plant foliage to have a mottled appearance. Such viruses come from a variety of unrelated lineages and consequently there is no taxon that unites all mosaic viruses.
[3] [9] The antibodies were specific to Tobacco mosaic virus, thus identifying and characterizing the virus as a pathogenic agent in tobacco mosaic disease. [9] [1] The specificity of the antibody for Tobacco mosaic virus, being unreactive with other viruses, proved to be a useful tool with which to diagnose a Tobacco mosaic virus infection. [3]
Martinus Beijerinck (1851–1931), a Dutch microbiologist and botanist, first used the term when studying the tobacco mosaic virus, becoming convinced that the virus had a liquid nature. [1] The word "virus", from the Latin for "poison", was originally used to refer to any infectious agent, and gradually became used to refer to infectious ...
