Question: What plants are affected by tobacco mosaic virus?

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.

Which 2 plants does the tobacco mosaic virus commonly infect?

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.

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?

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 a tobacco mosaic virus infect a human?

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.

Who first crystallized virus?

We will look at Wendell Meredith Stanley, who reported the first virus in crystalline form on June 28, 1935.

How do you test for tobacco mosaic virus?

Currently, enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) are the most commonly used methods to detect TMV in plants2. However, the processes of those methods are quite time-consuming, complex, and even challenging since the TMV may distribute unevenly in plant tissues at low level.

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.

How long does tobacco mosaic virus live on surfaces?

TMV is geographically widespread and economically significant. TMV is transmitted mechanically and is not known to have an invertebrate vector like some other viruses. It is very stable and persists in the soil and on surfaces and can survive almost 50 years in dead, dried plant tissue.

What was the first virus ever?

Two scientists contributed to the discovery of the first virus, Tobacco mosaic virus. Ivanoski reported in 1892 that extracts from infected leaves were still infectious after filtration through a Chamberland filter-candle. Bacteria are retained by such filters, a new world was discovered: filterable pathogens.
