Bacillus thuringiensis (Bt) strains have been used for designing novel:
Correct answer: D. Bioinsecticidal plants.
- A. Biofertilizers
- B. Bio-metallurgical techniques
- C. Bio-mineralization processes
- D. Bioinsecticidal plants.
Explanation
Bacillus thuringiensis strains have been used for designing bioinsecticidal plants. A gene from this bacteria has insecticidal property which is transferred to cotton plants to produce Bt cotton which is resistant to bollworm insect which is a major pest of cotton. Similarly, insects affecting maize; cabbage, sunflower etc., are also controlled by mutant strains of Bacillus thuringiensis bacteria.
