Which of the following is incorrect with respect to Bt toxin?
  • a)
    Bt toxin does not kill the bacteria themselves because toxin proteins occur in inactive form called protoxin.
  • b)
    Toxin can kill certain insects such as dipterans, coleopterans, and lepidopterans.
  • c)
    Bt toxin is commonly used to produce herbicide–resistant GM crops.
  • d)
    When an insect ingests an inactive toxin, it is converted into an active form of toxin due to the alkaline pH of the gut that solubilises the protein crystals.
Correct answer is option 'C'. Can you explain this answer?

Incorrect Statement about Bt Toxin

Explanation:

Bt toxin is a protein produced by the bacterium Bacillus thuringiensis. It is commonly used in organic farming as a biopesticide to control insect pests. The toxin is highly specific and only targets certain insects, such as dipterans, coleopterans, and lepidopterans. The toxin works by binding to receptors in the gut of the insect, causing the gut cells to rupture and leading to the death of the insect.

Incorrect Statement: Bt toxin is commonly used to produce herbicide–resistant GM crops.

Explanation: This statement is incorrect because Bt toxin is not used to produce herbicide-resistant GM crops. Instead, Bt genes are inserted into GM crops to make them resistant to insect pests. This allows farmers to reduce their use of chemical pesticides, which can be harmful to the environment and human health. Bt toxin itself does not provide any resistance to herbicides.

Bt toxin is commonly used to produce insecticide-resistant GM crops that can kill certain insects such as dipterans, coleopterans, and lepidopterans. Bacillus thuringiensis produces protein crystals encoded by the cry gene. This toxin exists in an inactive form called protoxins, but the inactive form gets converted into an active form in the alkaline pH of the insect gut, that solubilizes the crystals. This activated form of toxin binds to the midgut epithelial cells and create pores that causes death of the insect.
