Basic Genetic Modification
| Gene Introduced | Gene Source | Product | Function |
| cry1Ab | Bacillus thuringiensis subsp. kurstaki | Cry1Ab 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 |
| mcry3A | synthetic form of cry3A gene from Bacillus thuringiensis subsp. tenebrionis | modified Cry3A delta-endotoxin | confers resistance to coleopteran insects particularly corn rootworm pests by selectively damaging their midgut lining |
| pmi * | Escherichia coli | Phosphomannose Isomerase (PMI) enzyme | metabolizes mannose and allows positive selection for recovery of transformed plants |
| mepsps | Zea mays | modified 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) enzyme | confers tolerance to glyphosate herbicides |
| amy797E | synthetic gene derived from Thermococcales spp. | thermostable alpha-amylase enzyme | enhances bioethanol production by increasing the thermostability of amylase used in degrading starch |

Event Description
Regulatory and Biosafety Information
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.
