Tobacco mosaic virus (TMV)
The virus infects tobacco, related crops like green peper and tomatoes, as well as many other plants. Infections develop within days. The typical symptoms are a mosaic on the leaves (a mixture of light and darker green areas) as well as stunting. However, no symptoms may appear on some hosts. Control strategies include, resistant cultivars, sanitation, crop rotation, or cross protection (infecting plants with a mild strain).

The particles are long and tubular, about 300 x 18 nm, with a positive-sensed, single stranded RNA genome. The virus is transmitted by contact or in some cases through seeds and the particles can remain infectious for years in the soil or in plant residues.
