Question
- Which insects are killed by Bacillus thuringiensis?
- The Bt binds to which cells?
- In which plants Bt toxin is used?
✓
Answer
- The activated toxin binds to the surface of midgut epithelial cells and creates pores that cause cell swelling and lysis leading to the death of an insect.
- Bacillus thuringiensis forms protein crystals (Cry) during a particular phase of their growth. These crystals contain a toxic insecticidal protein.
