Bt corn has been made resistant from corn borer disease by introductio...
Introduction:
Bt corn, also known as genetically modified corn, has been developed to resist corn borer disease. This has been achieved by introducing a specific gene into the corn plant.
Answer:
The correct gene that has been introduced into Bt corn is cry l Ab. This gene is derived from the bacterium Bacillus thuringiensis (Bt) and codes for a protein called Cry1Ab. This protein is toxic to the larvae of the corn borer, a pest that can cause significant damage to corn crops.
When the corn borer larvae ingest the Cry1Ab protein, it binds to receptors in their digestive system and forms pores in their gut lining. This causes the larvae to stop feeding and eventually die.
The introduction of the cry l Ab gene into Bt corn has allowed farmers to reduce their use of chemical pesticides, which can have negative environmental impacts. Bt corn has also been shown to increase crop yields and improve the quality of the corn produced.
Conclusion:
In summary, the introduction of the cry l Ab gene into Bt corn has provided a sustainable solution to controlling corn borer disease. This has led to improved crop yields, reduced use of chemical pesticides, and a more environmentally friendly agricultural industry.
