Which Part Of Tobacco Plant Is Infected By Meloidogyne Incognita?

The nematode Meloidogyne incognita has caused an infection in the roots of the tobacco plant.

How does nematode Meloidogyne incognita affect tobacco plants?

The nematode Meloidogyne incognita infects the roots of tobacco plants. This nematode infection is quite frequent and damaging since it reduces the output of tobacco and lowers its quality. The nematode Meloidogyne incognita invades the roots of tobacco plants, causing a reduction in the amount of tobacco that can be harvested from each plant.

What is the host of Meloidogyne incognita?

  • Meloidogyne incognita is thought to have been tainted by a herbaceous plant that is cultivated on an annual basis.
  • All parts of the plant contain nicotine to varying degrees.
  • This is the major species that is utilized in the manufacturing of cigars, cigarettes, and a variety of other products for smokers.
  • The Agrobacterium organism serves as a vehicle for the production of double-stranded RNA in the host plant.

How do you develop resistance to tobacco infection?

The infection has spread to the roots of the tobacco plants. In order to create resistance to infection, a mechanism known as RNA I (Interference RNA) is utilized.

Which of the following nematodes infected the root of tobacco plant?

The roots of tobacco plants are susceptible to infection by the nematode Meloidogyne incognita.

What part of tobacco plant is tobacco made from?

To obtain an intoxicating effect from the leaves, they must first be dried and then eaten. The dried leaves can also be chewed like snuff or smoked like tobacco. This is the primary species that is utilized in the production of cigars, cigarettes, and other items catering to smokers’ needs.

How is transgenic tobacco plant protected against Meloidogyne incognita?

A mechanism based on RNA interference, which is a type of cellular defense that is possessed by all eukaryotic organisms, was used to defend the transgenic tobacco plant from the parasite.

Which of the following is used to protect tobacco plants from Meloidogyne?

Meloidegyne incognita is the problem, and it infects the roots of the tobacco plant, which leads to a significant decrease in output. RNA interference (RNAi) is the approach that and will be used to prevent this infection.

Which part is affected by Meloidogyne?

Therefore, the answer that you should select is ″Root.″

How do nematodes affect tobacco plants?

When tobacco is infected with nematodes, the roots can get bloated, develop knots, and even decay. This can happen both in the nursery and in the field. Plants may also become stunted, yellow, and wilt as a result of this condition. Nematodes are the culprits behind root knots.

What are the diseases of tobacco?

Cancer, heart disease, stroke, lung illnesses, diabetes, and chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis, are among diseases that can be caused by smoking cigarettes. Additionally, the chance of TB, certain eye disorders, and issues with the immune system, like as rheumatoid arthritis, is raised when a person smokes.

How do tobacco plants reproduce?

Although it is grown in farms as an annual plant, tobacco is essentially a perennial plant that reproduces by seed. The seeds are scattered throughout the beds. When planted on soil with a surface area of one hundred square yards, one ounce of seed can potentially result in four acres of flue-cured tobacco or three acres of burley tobacco.

Where is nicotine produced in the tobacco plant?

  • The roots of the tobacco plant are responsible for the production of nicotine, which is then stored in the plant’s leaves.
  • The nicotine content of the tobacco plant ranges from 0.3 percent to 0.5 percent of the plant’s dry weight.
  • Tobacco plants are classified as members of the nightshade family of plants.
  • Nicotine may be found in all tobacco species, including those used only for aesthetic purposes.

What is RNA interference in tobacco plant?

RNA interference, often known as RNAi, is a potential strategy for managing nuisance insects. This method works by suppressing the expression of key insect genes in order to disrupt the development and physiology of the insect. However, many insect orders are immune to this process.

How are tobacco plants benefited when nematode-specific genes are introduced?

Through a process known as DNA recombination, the genes that are unique to nematodes may be transferred into plant organisms. In this case, Agrobacterium is chosen because it carries the necessary gene and can attach itself to the DNA of tobacco plants, which ultimately results in the production of tobacco plants with increased disease resistance.

How does RNA interference help in developing resistance in tobacco plants against nematode infection?

  • When the roots of tobacco plants are infected by the nematode Meloidegyne incognitia, the plants’ ability to produce tobacco is significantly hindered.
  • The RNA interference mechanism, which is checked by the silencing of particular mRNA owing to a complementary ds RNA, can be utilized to ward off the infection and inhibit its spread.
  • The ds RNA forms a complex with the mRNA, which then inhibits its translation.

Which organism infects the root of tobacco plants and cause great loss of reduction?

Tobacco plants can become infected with incognita, which leads to a significant decrease in crop output.

Which of the following nematodes infects the roots of tobacco plants and causes a great reduction in yield?

The presence of Meloidogyne incognita, which infects the roots of tobacco plants, results in a significant decrease in output.

Which nematode causes root knot in tobacco plant?

Meloidogyne worms are responsible for the root knot nematode that affects tobacco. These nematodes include Meloidogyne incognita (southern root knot nematode), Meloidogyne javanica (Javanese root knot nematode), Meloidogyne hapla (northern root knot nematode), Meloidogyne
