Genetically modified soybean is a soybean (Glycine max) that has had DNA introduced into it in a way other than the combination of male and female gametes. This process may be carried out using "recombinant DNA (rDNA) technology." As a widely planted and versatile crop, soybeans have become a popular subject of genetic modification. To modify a soybean's genetic makeup, the gene to be introduced into the soybean must first be isolated. If the gene does not display an obvious phenotype, or visible characteristic, a marker gene must be linked to it so the modified cells and unmodified cells can be distinguished. According to Dr. Peter Celec, a professor in the Slovakian Comenius University's Department of Molecular Biology, the "marker genes typically confer resistance to a selective agent, often an antibiotic," so the unmodified cells can easily be killed off to leave only modified cells behind, and the "other [gene] is meant to confer a desirable phenotype, which is often agronomic (herbicide, pest, stress resistance) or related to food quality (shelf-life, taste, nutritional value).
