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 ...
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]
The human strains of Ebola virus, for example, incapacitate those infected extremely quickly and kill them soon after. As a result, those affected by this disease do not have the opportunity to travel very far from the initial infection zone. [72] Also, this virus must spread through skin lesions or permeable membranes such as the eye.
Movement proteins allow for local and systemic viral spread throughout a plant. [1] MPs were first studied in the Tobacco Mosaic Virus (TMV), where it was found that viruses were unable to spread without the presence of a specific protein. [1] In general, the plant viruses first move within the cell from replication sites to the plasmodesmata (PD).
[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]
West Nile virus; Many factors affect the incidence of vector-borne diseases. These factors include animals hosting the disease, vectors, and people. [21] Humans can also be vectors for some diseases, such as Tobacco mosaic virus, physically transmitting the virus with their hands from plant to plant. [citation needed]
