Basic Genetic Modification
| Gene Introduced | Gene Source | Product | Function |
| cry1F | Bacillus thuringiensis var. aizawai | Cry1F delta-endotoxin | confers resistance to lepidopteran insects by selectively damaging their midgut lining |
| pat | Streptomyces viridochromogenes | phosphinothricin N-acetyltransferase (PAT) enzyme | eliminates herbicidal activity of glufosinate (phosphinothricin) herbicides by acetylation |
| cry34Ab1 | Bacillus thuringiensis strain PS149B1 | Cry34Ab1 delta-endotoxin | confers resistance to coleopteran insects particularly corn rootworm by selectively damaging their midgut lining |
| cry35Ab1 | Bacillus thuringiensis strain PS149B1 | Cry35Ab1 delta-endotoxin | confers resistance to coleopteran insects particularly corn rootworm by selectively damaging their midgut lining |

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.
