How do you know if a plant has tobacco mosaic virus?
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 .
What plants does mosaic virus infect?
Mosaic viruses affect a wide range of edible crops – alfalfa, apples, beans, celery, corn, cucumbers, figs, peppers, spinach, tobacco and tomatoes are some of the more common ones. They can also infect ornamental plants like abultilon, delphinium, gladiola, marigold, petunia and one of the most notable, roses.
Can plants recover from virus?
Virus-induced diseases cause severe damages to cultivated plants resulting in crop losses. Interestingly, in some cases, the diseased plants are able to re-gain health, further grow and develop normally.
Does mosaic virus live in soil?
Unlike TMV (tobacco mosaic virus), CMV is not seedborne in tomato and does not persist in plant debris in the soil or on workers’ hands or clothing. The occurrence of this virus is erratic and unpredictable; consequently, control of this disease can be difficult.
Can you eat cucumbers with mosaic virus?
Yes, you can eat squash and melons that are infected with mosaic virus. These viruses are not harmful to humans and do not cause the fruit to rot. Often the discoloration is only skin deep. In cases where fruit are severely distorted, the texture of the fruit may be affected and may not be desirable for eating.
Can humans get tobacco mosaic virus?
Tobacco mosaic virus (TMV), a widespread plant pathogen, is found in tobacco (including cigarettes and smokeless tobacco) as well as in many other plants. Plant viruses do not replicate or cause infection in humans or other mammals.
How can we prevent the tobacco mosaic virus from spreading?
Controlling the spread of tobacco mosaic virus
wash their hands after handling infected plants. wash tools that have come into contact with infected plants in detergent or bleach. rotate the crops they grow in a contaminated field – they must not grow tobacco or tomato plants in the field for at least two years.
