The maize (Zea mays) was modified for resistance to insects and tolerance to herbicides. For resistance to Lepidopteran pests, the modified maize expresses a Bacillus thuringiensis chimeric delta endo-toxin Cry1Da2, which forms non-specific, ion conducting pores in the apical membrane of the midgut epithelial cells and leads to larval death. For tolerance to glyphosate, the modified maize expresses Streptomyces sviceus DGT28 5-enolpiruvilshikimate- 3-phosphate synthase, which allows for the continuing functioning of the shikimate pathway by avoiding inhibition from the herbicidal compound.
Le terme « organisme récepteur » désigne un organisme (non modifié ou déjà modifié) ayant fait l'objet d'une modification génétique, tandis que les « organismes parentaux » désignent les organismes impliqués dans un croisement ou une fusion cellulaire pour générer un organisme modifié.

The modified maize (Zea mays) contains two gene cassettes: Bacillus thuringiensis cry1Da2 and Streptomyces sviceus DGT28 5-enolpiruvilshikimate- 3-phosphate synthase (dgt28-epsps).
The cry1Da2 coding sequence is under control of a Zea mays ubiquitin (ubi1) promoter and terminator. The 5' untranslated region contains a ubi1 leader and intron to enhance the expression of cry1Da2. Due to the nature of the promoter, high levels of expressions are expected from this cassette.
The dgt28-epsps coding sequence is under control of the a ubi1 promoter and terminator. The 5' untranslated region contains a ubi1 leader and intron to enhance the expression of dgt28-epsps. A chimeric transit peptide (TraP8) was added to direct the translated DGT28-EPSPS protein to the chloroplast. Due to the nature of the promoter, high levels of expressions are expected from this cassette.

Note
- The cry1Da2 coding sequence is a chimeric sequence consisting of cry1Da2 gene encoding an insecticidal core toxin and a derivative of the cry1Ab gene.
- The TraP8 coding sequence is a chimeric sequence consisting of both Brassica napus and Brassica rapa donor organisms.
- The Cry1Da2 protein is 603 amino acids in length, including the last 9 amino acids derived from cry1Ab, and has a molecular weight of approximately 68 kDa.
- The DGT28-EPSPS protein has a length of 481 amino acids and a molecular weight of approximately 51 kDa which includes the 65-amino acid TraP8 peptide as well as a 2-amino acid linker.
- The T-DNA contains two attB recombination sites, two engineered landing pad regions and four zinc finger nuclease target recognition sites.
- Southern-by-Sequencing analysis confirmed a single insertion of the T-DNA into the maize genome and the absence of plasmid backbone sequences. No unexpected insertions, deletions, rearrangements or junctions were detected.
- PCR confirmed presence of the transgenic cassettes, and southern analysis indicated stable inheritance across generations during development.

- Transformation method: Immature maize embryos were harvested from a surface‐sterilized ear of B104 maize approximately 10‐14 days after pollination and inoculated with Agrobacterium tumefaciens strain DAt13192. Glyphosate was applied to select for transformants.
- DAS-01131-3 seed was deposited with the American Type Culture Collection on May 26, 2021, as ATCC PTA-127077.
