Mon 863 is a variety of maize. It was in the news for the following reason:
- It is a genetically modified dwarf variety which is resistant to drought
- It is a genetically modified variety which is pest resistant
- It is a genetically modified variety with ten times higher protein content than regular maize crop
- It is a genetically modified variety used exclusively for bio-fuel production
Explanation
Option (b) is correct
- MON 863 is a genetically modified maize variety developed by Monsanto. It was engineered to express the Cry3Bb1 protein derived from the soil bacterium Bacillus thuringiensis. This protein is toxic to specific insect pests, particularly the corn rootworm, which is one of the most destructive pests affecting maize crops globally. The Cry proteins act by binding to receptors in the gut lining of the insect larvae, leading to disruption of gut integrity and eventual death of the pest.
