A genetically modified organism, also popularly known as GMO, is any kind of organism, inside of which the genes or its other genetic substance have been altered by using recombinant DNA (Vitro) techniques. A plant, like soybean or corn, is reflected as genetically modified when genetic substance from outside of the organism is injected into its DNA sequence. Plants, which are grown from harvested seed from the genetically modified plants, will also be containing the genetic modification.

The most common type of genetic modification in crops discusses insect or herbicide resistance to plans such as the Bacillus thurigenesis gene. The Bt resistance is accomplished by the production of a novel protein, which is encoded by the injected DNA sequence. In plants, which are genetically modified for agricultural purposes have some common genetic elements in the recombinant sections of DNA, which are artificially inserted in the natural plant genome.

Each of the inserted DNA sequences comprises at least a protein-coding site (structural gene), a terminator, and a promoter. Several of these have been prepared and arranged artificially, including corn, flax, cotton, chicory, sugar beet, papaya, melon, potato, mustard, rice rapeseed, squash, soybean, barley, tomato. Others, such as wheat are still under development.
