TMV is a single-stranded RNA virus that commonly infects Solanaceous plants, which is a plant family that includes many species such as petunias, tomatoes and tobacco.
Which plant is affected by mosaic disease?
mosaic, plant disease caused by various strains of several hundred viruses. A number of economically important crops are susceptible to mosaic infections, including tobacco, cassava, beet, cucumber, and alfalfa.
Who does tobacco mosaic virus affect?
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.
Is tobacco mosaic virus?
Tobacco mosaic virus (TMV) is a positive-sense single-stranded RNA virus species in the genus Tobamovirus that infects a wide range of plants, especially tobacco and other members of the family Solanaceae.

Can any plant get mosaic virus?
Mosaic viruses affect more than 150 types of plants, including many fruits, vegetables, and flowers. The disease is characterized by leaves that are mottled with yellow, white, and light or dark green spots and streaks (in other words, a “mosaic” of these colors).
How many plants are affected by tobacco mosaic virus?
Tobacco mosaic virus (TMV) is named for one of the first plants in which it was found in the 1800s. However, it can infect well over 350 different species of plants. TMV is made up of a piece of nucleic acid (ribonucleic acid; RNA) and a surrounding protein coat.
Which plant disease is caused by virus?
|Rank||Virus||Author of virus description|
|1||Tobacco mosaic virus (TMV)||Karen-Beth G. Scholthof|
|2||Tomato spotted wilt virus (TSWV)||Scott Adkins|
|3||Tomato yellow leaf curl virus (TYLCV)||Henryk Czosnek|
|4||Cucumber mosaic virus (CMV)||Peter Palukaitis|
How do plants get tobacco mosaic virus?
Transmission from plant to plant
TMV is very easily transmitted when an infected leaf rubs against a leaf of a healthy plant, by contaminated tools, and occasionally by workers whose hands become contaminated with TMV after smoking cigarettes.
What will happen to tobacco plants if infected by tobacco mosaic virus?
Tobacco mosaic virus causes a mottled browning of tobacco leaves, and accordingly is of major economic importance. It also infects other crops, most notably tomatoes. The virus is spread mechanically from infected plants to scratched or damaged leaves of normal plants.
Does mosaic virus stay in soil?
Great for the aphid, but really unfortunate for the hundreds of plants it can bite during those few hours. If there’s any good news here it’s that unlike some other mosaics, Cucumber Mosaic Virus can’t be passed along through seeds and won’t persist in plant debris or soil.
What type of pathogen is tobacco mosaic virus?
TMV is a viral plant pathogen and a member of a large group of viruses within the genus Tobamovirus.
Can you eat a watermelon 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.
Is mosaic virus common in houseplants?
Typically, most houseplant viruses are named after the plant that they affect, plus having “mosaic” in the name. There are, unfortunately, quite a few viruses that affect houseplants. If you have viral diseases of houseplants, there is regrettably no cure, so you’ll have to destroy your plant.
Can tomatoes get mosaic virus?
For example, tomato mosaic virus most often infects tomatoes, but can also infect pepper, potato, apple, pear, cherry and numerous weeds, including pigweed and lamb’s quarters. Tobacco mosaic virus can infect ornamentals and weeds including cucumber, lettuce, beet, pepper, tomato, petunia, jimson weed and horsenettle.
