About Tobacco Mosaic Virus
- Tobacco mosaic virus infects cells in the leaves of the plant. This leads to a 'mosaic' pattern on the leaves which is where it gets its name.
- Tobacco mosaic virus damages the leaves reducing photosynthesis and therefore slowing the growth of the plant.
- Tobacco mosaic virus can be spread by contact between an infected and a healthy plant and by animal vectors.
- There is no treatment for tobacco mosaic virus so farmers grow strains of resistant plants.
- The number of tobacco mosaic virus infections can be reduced by killing the animal vectors.
