The discovery of viruses is attributed to Dmitry Ivanovsky, a Russian microbiologist who, between 1887 and 1890, investigated the mosaic disease of tobacco plants occurring in Eastern Europe. He found that the disease-causing factor passed through a porcelain filter that had pores fine enough to hold back bacteria.
Who demonstrated the cause of the tobacco mosaic disease?
In 1879, Adolph Mayer, working in the Netherlands, investigated this disease and named it the mosaic disease of tobacco. He reported that the “the harm done by this disease is often very great … and it has caused the cultivation of tobacco to be given up entirely” in certain places (17).
Who discovered structure of TMV?
Tobacco mosaic virus occupies a unique place in the history of virology and was in the forefront of virus research since the end of the nineteenth century. It was the German Adolf Mayer, working in the Netherlands, who in 1882 first described an important disease of tobacco which he called tobacco mosaic disease.
What are the symptoms of tobacco mosaic virus?
Symptoms associated with TMV infections:
- mosaic pattern of light and dark green (or yellow and green) on the leaves.
- malformation of leaves or growing points.
- yellow streaking of leaves (especially monocots)
- yellow spotting on leaves.
- distinct yellowing only of veins.
How can we prevent tobacco mosaic virus?
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.
Who gave the name of virus?
Viruses are named based on their genetic structure to facilitate the development of diagnostic tests, vaccines and medicines. Virologists and the wider scientific community do this work, so viruses are named by the International Committee on Taxonomy of Viruses (ICTV).
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.
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.
