Oftentimes, researchers find themselves working not with E. coli or other bacteria, but with plant organisms that are unaffected by antibiotics. In these instances, antibiotic resistance is replaced with herbicidal resistance. While the overall process remains essentially the same, herbicide resistance falls under a different category of selectable genetic markers. | |||
One of the most common forms of herbicide resistance found in the world is glyphosate resistance. The Monsanto corporation introduced glyphosate resistance into soybeans in 1996, and provides an example of the commercial application of selectable genetic markers. Since then, Monsanto has incorporated glyphosate resistance into other plants such as canola, corn, and alfalfa. Approximately 50% of all agricultural land in the United States is now occupied by these variants, attesting to the power of selectable genetic markers. | |||
