Question

What causes tobaco mosaic virus​

Answer 1

THE TOBACCO MOSAIC VIRUS

The virus is spread mechanically from infected plants to scratched or damaged leaves of normal plants. The virus is very stable in nature, and has been isolated from tobacco produce several years after their preparation.

Answer 2

Answer:

The tobacco mosaic virus infects tobacco and lots of other closely related species like tomatoes and peppers. It is transmitted by

contact between plants, either naturally or on the hands of farmers. It infects the chloroplasts of plant leaves and changes their colour from green to yellow or white in a mosaic pattern. It can also make leaves crinkled or

curled up. This reduces the plant's ability to photosynthesise and

grow properly, which can reduce farmers' crop yields.
