Basic Genetic Modification
| Gene Introduced | Gene Source | Product | Function |
| bar | Streptomyces hygroscopicus | phosphinothricin N-acetyltransferase (PAT) enzyme | eliminates herbicidal activity of glufosinate (phosphinothricin) herbicides by acetylation |
| cry1Ac | Bacillus thuringiensis subsp. Kurstaki strain HD73 | Cry1Ac delta-endotoxin | confers resistance to lepidopteran insects by selectively damaging their midgut lining |
| cry2Ab2 | Bacillus thuringiensis subsp. kumamotoensis | Cry2Ab delta-endotoxin | confers resistance to lepidopteran insects by selectively damaging their midgut lining |
| nptII * | Escherichia coli Tn5 transposon | neomycin phosphotransferase II enzyme | allows transformed plants to metabolize neomycin and kanamycin antibiotics during selection |
| uidA * | Escherichia coli | beta-D-glucuronidase (GUS) enzyme | produces blue stain on treated transformed tissue, which allows visual selection |
| aad * | Escherichia coli | 3''(9)-O-aminoglycoside adenylyltransferase enzyme | allows selection for resistance to aminoglycoside antibiotics such as spectinomycin and streptomycin |

Regulatory and Biosafety Information
Detection Methods
The GM Approval Database, or GMAD, is one of ISAAA’s unique features that compiles all the available information about biotech/GM crops that have been approved for planting and importation for food and feed, and commercialization. ISAAA sources out the information from publicly available decision documents per country, Biosafety Clearing Houses and peer-reviewed scholarly articles to maintain the credibility of the database. Your contribution can help expand and maintain the GMAD and make useful information more available to researchers, students, and the general public. You can help by donating as little as $10.
