Event Name: DP305423 x GTS 40-3-2
Event Code : DP-3Ø5423-1 x MON-Ø4Ø32-6
Trade Name: not available
Crop: Glycine max L. - Soybean
Developer: DuPont (Pioneer Hi-Bred International Inc.)
Method of Trait Introduction: Conventional breeding - cross hybridization and selection involving transgenic donor(s)
GM Traits: Glyphosate herbicide tolerance , Sulfonylurea herbicide tolerance , Modified oil/fatty acid
Commercial Trait: (Stacked) Herbicide Tolerance (HT) + Modified Product Quality (PQ)
Basic Genetic Modification
| Gene Introduced | Gene Source | Product | Function |
| gm-hra * | Glycine max | modified acetolactate synthase (ALS) enzyme | confers tolerance to applications of sulfonylurea – based herbicides |
| gm-fad2-1 (partial sequence) | Glycine max | no functional enzyme is produced (expression of the endogenous fad2-1 gene encoding omega-6 desaturase enzyme was suppressed by the partial gm-fad2-1 gene fragment) | blocks the formation of linoleic acid from oleic acid (by silencing the fad2-1 gene) and allows accumulation of oleic acid in the seed |
| 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 |

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.
