Detailed explanation-1: -“Bt crops are transgenic crops that are genetically engineered from the DNA of bacterium Bacillus thuringiensis.” Bt Crops are transgenic crops that produce the same toxin as the bacterium Bacillus thuringiensis in the plant cell, thereby, protecting the crops from pests.

Detailed explanation-2: -Cotton is genetically engineered to produce a toxin that kills the bollworm, one of cotton’s primary pests. This pest-resistant cotton is engineered with a gene from the bacteria Bacillus thurengiensis or “Bt, ” and is called Bt cotton.

Detailed explanation-3: -Bt cotton is a genetically modified pest resistant plant cotton variety, which produces an insecticide to combat bollworm.

Detailed explanation-4: -The Bt cotton landscape. In India, the first genetically modified crop of cotton was officially introduced in the year 2002. This cotton carried genes from the bacterium Bacillus thuringiensis, and is, therefore, called Bt cotton. These genes produce proteins that protect the cotton plant from the pest called bollworm.

Detailed explanation-5: -Pest resistant GM crops (primarily cotton and maize), have been genetically modified so they are toxic to certain insects. They are often called Bt crops because the introduced genes were originally identified in a bacterial species called Bacillus thuringiensis.
