Agricultural biotechnology, also known as agritech, is an area of agricultural science involving the use of scientific tools and techniques, including genetic engineering, molecular markers, molecular diagnostics, vaccines, and tissue culture, to modify living organisms: plants, animals, and microorganisms. [1]
Biotechnology has several applications in the realm of food security. Crops like Golden rice are engineered to have higher nutritional content, and there is potential for food products with longer shelf lives. [92] Though not a form of agricultural biotechnology, vaccines can help prevent diseases found in animal agriculture.
Genetically modified crops (GM crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering methods. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors .
Genetically modified crops are genetically modified plants that are used in agriculture. The first crops provided are used for animal or human food and provide resistance to certain pests, diseases, environmental conditions, spoilage or chemical treatments (e.g. resistance to a herbicide). [16]
Genetically modified crops (GM crops) are genetically modified plants that are used in agriculture.

A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques.The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination". [1]
Agronomists use biotechnology to extend and expedite the development of desired characteristics. [1] Biotechnology is often a laboratory activity requiring field testing of new crop varieties that are developed. In addition to increasing crop yields agronomic biotechnology is being applied increasingly for novel uses other than food.
Using a minor crop such as safflower or tobacco avoids the greater political pressures and risk to the food supply involved with using staple crops such as beans or rice. Expression of proteins in plant cell or hairy root cultures also minimizes risk of gene transfer, but at a higher cost of production.
