Basic Genetic Modification
| Gene Introduced | Gene Source | Product | Function |
| cry1B.34.1 | Bacillus thuringiensis | Cry1B.34.1 protein | Binds to receptors in the insect midgut, disrupts midgut epithelial cells, and causes death of susceptible lepidopteran insect larvae. It is a truncated version of the Cry1B.34 Bt toxin protein. |
| cry1B.61.1 | Bacillus thuringiensis (Bt) | Cry1B.61.1 protein | Produces an insecticidal Bt Cry protein that binds to receptors in the digestive tract of susceptible lepidopteran insects, disrupting midgut epithelial cells and leading to insect death. It provides an additional mode/site of action for pest control. |
| ipd083Cb | Giant maidenhair fern, Adiantum trapeziforme var. braziliense | IPD083Cb protein | Produces a novel insecticidal protein that binds to target sites in the midgut of susceptible lepidopteran insects, disrupting gut epithelial cells and causing insect death. It acts through target sites different from many Bt proteins, helping delay insect resistance development. |
| gm-hra_1 | Soybean (Glycine max) | GM-HRA_1 protein (modified acetolactate synthase, ALS enzyme) | Encodes a modified ALS enzyme involved in the biosynthesis of branched-chain amino acids (isoleucine, leucine, and valine). Two amino acid substitutions make the enzyme tolerant to ALS-inhibiting herbicides while retaining normal enzymatic activity. |

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.
