Mon 863 is a genetically modified variety of maize that was developed by the biotech company Monsanto. It was in the news primarily for its controversial approval for commercial cultivation in various countries.

The variety was engineered to be pest-resistant, specifically against the European corn borer, which is a major pest of maize crops. Mon 863 contains a gene from the bacterium Bacillus thuringiensis (Bt), which produces a protein toxic to the corn borer. This Bt protein is only harmful to specific insect pests and has been shown to be safe for human consumption.

While Mon 863 was not specifically designed for drought resistance, it has been suggested that it may have some level of tolerance to drought stress due to its reduced susceptibility to pest damage. However, this is not a primary trait of the variety, and it is not marketed or promoted as a drought-tolerant crop.

There is no evidence to suggest that Mon 863 has a higher protein content than regular maize crop or that it is used exclusively for biofuel production.

Overall, Mon 863 is a genetically modified variety of maize that was developed for its pest-resistant trait and has been a subject of controversy regarding its commercial cultivation and potential risks to human health and the environment.
