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 ...
TMV MP30 localizes to plasmodesmata when fused to GFP. This image was captured using confocal laser scanning microscopy. A movement protein (MP) is a specific virus-encoded protein that is thought to be a general feature of plant genomes. For a virus to infect a plant, it must be able to move between cells so it can spread throughout the plant.
Comparison between crystallisation of salt (left) and Tobacco Mosaic virus (right) as seen through electron microscopy. Virus crystallisation is the re-arrangement of viral components into solid crystal particles. [1] The crystals are composed of thousands of inactive forms of a particular virus arranged in the shape of a prism. [2]
[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 main differences between these groups are genome sequences, and ...
Adolf Eduard Mayer (9 August 1843 – 25 December 1942) was a German agricultural biologist whose work on tobacco mosaic disease played an important role in the discovery of tobacco mosaic virus and viruses in general. Mayer was born in 1843 into the family of a high school teacher in Oldenburg.
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 host-virus (in this case, TMV) for the machinery necessary for them to reproduce.
In 1935, American biochemist and virologist Wendell Meredith Stanley examined the tobacco mosaic virus (TMV) and found it to be mainly made from protein. [7] A short time later, this virus was shown to be made from protein and RNA. [8] Rosalind Franklin developed X-ray crystallographic pictures and determined the full structure of TMV in 1955. [9]
Tobacco mosaic virus (TMV) and cauliflower mosaic virus (CaMV) are frequently used in plant molecular biology. Of special interest is the CaMV 35S promoter, which is a very strong promoter most frequently used in plant transformations. Viral vectors based on tobacco mosaic virus include those of the magnICON® and TRBO plant expression ...
