Basic Genetic Modification
| Gene Introduced | Gene Source | Product | Function |
| aad-1 | synthetic form of the aad-1 gene from Sphingobium herbicidovorans | aryloxyalkanoate dioxygenase 1 (AAD-1) protein | detoxifies 2,4-D herbicide by side-chain degradation and degrades the R-enantiomers of aryloxyphenoxypropionate herbicides |
| cp4 epsps (aroA:CP4) | Agrobacterium tumefaciens strain CP4 | herbicide tolerant form of 5-enolpyruvulshikimate-3-phosphate synthase (EPSPS) enzyme | decreases binding affinity for glyphosate, thereby conferring increased tolerance to glyphosate herbicide |

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.
