Biotechnology Definition and Examples Continued
Biotechnology has been used with plants in many applications, including:
- Insect protection that comes from within the plants, rather than from externally applied pesticides.
- Herbicide tolerance that makes weed control more effective and reduces the amount of herbicide applications needed.
- Disease protection that comes from within the plant to provide protection from specific viral or fungal diseases.
- Improved nutritional profiles, food quality and/or food processing advantages (1).
- By modifying a plant’s production of linoleic acid, it can better withstand cold temperatures and frost.
- Desirable functional characteristics --
- Potatoes rDNA-engineered for a higher starch content will absorb less oil when deep fried, resulting in French fries with less fat (1).
- Tomatoes bioengineered for delayed ripening may stay on the vine longer, resulting in better flavor and color before being picked and shipped to market (1).
- Enhanced nutritional characteristics -- Adding Vitamin A to rice (called Golden Rice).
