A significant environmental concern about using genetically modified crops is possible cross-breeding with related crops, giving them advantages over naturally occurring varieties. One example is a glyphosate-resistant rice crop that crossbreeds with a weedy relative, giving the weed a competitive advantage.
While there are some legitimate concerns when it comes to GMOs and the Big Four companies that manufacture them -- Monsanto , DuPont Dow Chemical and Syngenta -- the benefits of using the seeds ...
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]
One of the best-known and controversial applications of genetic engineering is the creation and use of genetically modified crops or genetically modified livestock to produce genetically modified food. Crops have been developed to increase production, increase tolerance to abiotic stresses, alter the composition of the food, or to produce novel ...
Genetically modified organisms refers to any plant, animal or microorganism that has been genetically altered, due to modern biotechnology like genetic engineering. Often, GMOs are labeled “GE ...
Genetically modified plants have been engineered for scientific research, to create new colours in plants, deliver vaccines, and to create enhanced crops. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors .
Regulations regarding the commercialisation of genetically modified crops are mostly conducted by individual countries. For cultivation, environmental approval determines whether a crop can be legally grown. Separate approval is generally required to use GM crops in food for human consumption or as animal feed.

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.
