In Bt-cotton and Bt-brinjal, what is the meaning of Bt?

🔑Key Points:
The bacteria Bacillus thuringiensis contain genes that produce bt toxin.
This toxin is encoded by the cry gene, which is present in its genome.
The genes are isolated and inserted into the plants such as cotton and brinjal.
The plants which form by the insertion of a sequence of nucleotide is termed transgenic plant.
Bt-cotton and Bt-brinjal are insect-resistant plants.
In Bt-cotton and Bt-brinjal,  the meaning of Bt is Bacillus thuringiensis.
The cry gene is inserted into the plant body and produces toxins.
The toxin is ingested by the insect, in the body gets activated, thus killing them.

🔴Additional Information:

• Bacillus thermophilus:
It is rod-shaped bacteria.
It can live in hotspring and can tolerate high temperatures.
It forms biofilms on the products.

• Bordetella trematum:
It is gram-negative bacteria.
It causes respiratory infections.
It enters the body from the wound site.

• Bacillus thermolactis:
It can tolerate high temperatures.
It is present in dairy products.
It produces acid and thus destroys the dairy product.
