Harvesting the Benefits Crop biotechnology is playing an integral role in the evolution of agriculture. From genetic engineering to improve plant varieties, to more effective and environmentally sustainable methods of fertilization and weed control - the range of applications is extensive and expanding continuously. These technologies allow for many improvements in the quantity and quality of food produced. By breeding plants selected for specific genetic traits scientists can increase the performance potential of crops. Genetically engineered plant varieties can offer farmers crops that are less vulnerable to pests and weather conditions.
Consumers benefit from food products with added flavour and nutrition.
Genes for traits such as drought tolerance or resistance to insect pests can be transferred from one variety to another. Genes can also be transferred from other plant species, or even from microorganisms or animals. Crop scientists use a variety of other genetically-based breeding methods to produce plants which are resistant to disease, insects, and herbicides. Certain DNA sequences, called molecular markers, are located near genes for desirable traits. These distinctive patterns act like 'genetic bookmarks,' enabling scientists to detect the targeted traits in the genetic blueprints of seedlings.
