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 ...
Helen Alice Purdy Beale, (September 19, 1893 – November 5, 1976) was an American virologist who made significant contributions to the fields of plant virology and immunology.
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. The first X-ray diffraction pictures of the crystallised virus were obtained by Bernal and Fankuchen in 1941.

The United States Army Medical Research Institute of Infectious Diseases (USAMRIID; / j uː ˈ s æ m r ɪ d /) is the United States Army's main institution and facility for defensive research into countermeasures against biological warfare.
In the diagnostic laboratory, virus infections can be confirmed by a myriad of methods. Diagnostic virology has changed rapidly due to the advent of molecular techniques and increased clinical sensitivity of serological assays. [1]
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.
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]
Dmitri Iosifovich Ivanovsky (alternative spelling Dmitrii or Dmitry Iwanowski; Russian: Дми́трий Ио́сифович Ивано́вский; [a] 28 October 1864 – 20 June 1920) was a Russian botanist, the co-discoverer of viruses (1892), and one of the founders of virology.
