What is the family for Tobamovirus?

VirgaviridaeTobamovirus / FamilyVirgaviridae is a family of positive-strand RNA viruses. Plants serve as natural hosts. The name of the family is derived from the Latin word virga, as all viruses in this family are rod-shaped. There are currently 59 species in this family, divided among seven genera. Wikipedia

Is Tobamovirus a pathogen?

Tobamovirus is a group of viruses that have become serious pathogens of crop plants.

What kingdom tobacco mosaic virus is?

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.

What is TMV in biology?

Tobacco mosaic virus (TMV) encodes four known functional proteins: the 126 and 183 kDa replication-associated proteins, the movement protein (MP), and the structural capsid or coat protein (CP).

Who discovered 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:

  • stunting.
  • 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 does tobacco mosaic virus reproduce?

Chewing insects such as grasshoppers and caterpillars occasionally spread the virus but are usually not important in spread. Vegetative propagation perpetuates TMV and other virus diseases. Cuttings taken from an infected plant usually are infected even if no symptoms are immediately exhibited by the cutting.

Who discovered TMV virus?

Why is it called 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.

Is TMV prokaryotic or eukaryotic?

Expert-verified answer TMV is neither considered as the prokaryote nor a eukaryote. TMV or a tobacco mosaic virus which is positive sense RNA virus which really affects a wide range of the plants especially tobacco. This infection is caused by the characteristics pattern like discoloration of the leaves.

What is the structure and composition of TMV?

Tobacco mosaic virus (TMV; Tobamovirus, Virgaviridae) is a rodlike virus with a length of 300 nm and diameter of 18 nm. TMV capsids are composed of 2130 identical protein subunits, which assemble around the viral ssRNA to form a helical structure, with a hollow central cavity of 4 nm diameter.

Who Crystallised TMV?

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