Basic Genetic Modification
| Gene Introduced | Gene Source | Product | Function |
| cp4 epsps | Agrobacterium tumefaciens (strain CP4) | 5-enolpyruvylshikimate-3-phosphate synthase | confers tolerance to glyphosate herbicides by providing an alternative metabolic pathway for aromatic amino acid synthesis that is not inhibited by the chemical |
| cry1B.868 | Bacillus thuringiensis | crystalline protein prototoxin Cry1B.868 | The cry1B.868 coding sequence is under control of a Zea mays ubiquitin promoter and an Oryza sativa lipid transfer-like protein terminator. The promoter contains the promoter, leader and intron sequences from the maize ubiquitin gene. High levels of transcription are expected in all tissues due to the constitutive nature of the promoter. |
| cry1Da_7 | Bacillus thuringiensis | crystalline protein prototoxin Cry1Da_7 | The cry1Da_7 coding sequence is under control of a Setaria italica promoter and an O. sativa gos2 terminator. The first intron of the rice actin 15 gene was also included and likely improves expression of the gene. |
| vip3Aa20 | Bacillus thuringiensis strain AB88 | vegetative insecticidal protein (vip3Aa variant) | confers resistance to feeding damage caused by lepidopteran insects by selectively damaging their midgut |
| pmi * | Escherichia coli | Phosphomannose Isomerase (PMI) enzyme | metabolizes mannose and allows positive selection for recovery of transformed plants |
| cry3Bb1 | Bacillus thuringiensis subsp. kumamotoensis | Cry3Bb1 delta endotoxin | confers resistance to coleopteran insects particularly corn rootworm by selectively damaging their midgut lining |

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.
