Santos Silva discovered that the cowpea mosaic virus could not penetrate the vascular system of some tobacco plants. In the future, researchers want to establish the reason for this.
Transmission to other plants completes a virus’s life cycle. History The first plant virus to be discovered was found on the leaves of tobacco plants in the late 19th Century.
Now scientists have turned to a virus, the tobacco mosaic virus (TMV), that commonly infects tobacco plants. TMV is rod-shaped, about 18 nanometers wide by 200 to 300 nanometers long.
Research to date has unveiled a remarkable chemical diversity among metabolites derived from tobacco species, including flavonoids, isoflavones, isoindolin-1-ones and sesquiterpenes.

This vaccine is different in that it is developed through the creation of an entirely separate virus — the Tobacco Mosaic Virus. “We’ve been able to genetically engineer a plant virus,” Arntzen said. ...
A classic example is tobacco mosaic virus. If you smoke, it can be transferred from your hands or shoes to other host plants in the solanaceae family, such as tomatoes, potatoes, eggplants and ...
TRV was first identified in tobacco, but it can affect 400 kinds of plants, from tulips to chickweed. Many of these plants don’t show any effect of the virus and it stays only in the roots.
The tobacco mosaic virus is composed of protein and nucleic acid, which may be separated by gentle chemical treatment. When the two components are mixed together, they form infective virus particles ...
