The maize (Zea mays) was produced through crossing modified parental lines for resistance to insect pests and tolerance to herbicides. For protection from Lepidoptera insects, the maize expresses Cry1F and VIP3Aa20 proteins, which have a pore-forming mode of action that selectively damages the midgut epithelium line of feeding larvae. For tolerance to glufosinate, the maize expresses Streptomyces viridochromogenes phosphinothricin N-acetyltransferase, which inactivates phosphinothricin through acetylation. For tolerance to aryloxyphenoxypropionate and 2,4-dichlorophenoxyacetic acid herbicides (acetyl‐CoA carboxylase inhibitors), the modified maize expresses Sphingobium herbicidovorans aryloxyalkanoate dioxygenase, which cleaves 2,4-dichlorophenoxyacetic acid into non-herbicidal dichlorophenol and glyoxylate, as well as inactivates aryloxyphenoxypropionate. In addition, the modified maize also contains a gene cassette for Escherichia coli phosphomannose isomerase, which was used as a selectable marker during transformation by allowing for the transformed maize plants to use mannose as a carbon source.
El término "organismo receptor" hace referencia a un organismo (modificado o no modificado) que fue objeto de una modificación genética, en tanto que "organismos parentales" hace referencia a los implicados en el cruzamiento o la fusión de células.

DNA insert from TC1507 (DAS-Ø15Ø7-1) vector PHI8999A
DNA fragment PHI8999A contains two adjacent plant gene expression cassettes for Bacillus thuringiensis cry1F and Streptomyces viridochromogenes phosphinothricin N-acetyltransferase (pat).
Transcription of cry1F is directed by the promoter and first exon and intron of the maize (Zea mays) ubiquitin gene and terminates at the Agrobacterium tumefaciens ORF25 terminator.
Transcription of the pat gene commences from a Cauliflower mosaic virus 35S promoter and ends at the Cauliflower mosaic virus 35S terminator.

Transcription of the pat gene commences from a Cauliflower mosaic virus 35S promoter and ends at the Cauliflower mosaic virus 35S terminator.
Note:
- The coding sequence of both genes has been optimized to achieve a high level of expression in maize.
- The sequences of the complete cry1F and pat are identical to those in the original plasmid.
- The Cry1F protein includes the F604K (phenylalanine to lysine at position 604) amino acid substitution, which was introduced to create a specific restriction site for cloning purposes.
DNA insert from MIR162 (SYN-IR162-4) vector pNOV1300
The parental genome contains two gene cassettes: a variant of the native Bacillus thuringiensis vegetative insecticidal protein 3Aa (vip3Aa20) and Escherichia coli phosphomannose isomerase.
Transcription of vip3Aa20 commences at the Zea mays ubiquitin promoter and then transcribes vip3Aa20 followed by intron 9 of Z. mays phosphoenolpyruvate carboxylase, before terminating at the Cauliflower mosaic virus 35S terminator. Higher levels of expression are expected due to the promoter and the enhancement by the intron.
The pmi coding sequence is under the control of Z. mays ubiquitin promoter and transcription terminates at the Agrobacterium tumefaciens nopaline synthase gene (nos) terminator.

The pmi coding sequence is under the control of Z. mays ubiquitin promoter and transcription terminates at the Agrobacterium tumefaciens nopaline synthase gene (nos) terminator.
Note:
- Southern blot analyses demonstrated that the T-DNA insert contains: (i) single copies of a vip3Aa20 gene and a pmi gene; (ii) two copies of the maize ubiquitin promoter; (iii) one copy of the nos terminator; and (iv) no backbone sequences from transformation plasmid pNOV1300.
- In the parental MIR162 maize, a variant of the native B. thuringiensis vegetative insecticidal protein 3Aa (vip3Aa20), named vip3Aa19, which has codon changes that result in a single M129I amino acid substitution was inserted into the transformation cassette. During the transformation process an additional DNA mutation resulted in a K284Q amino acid substitution.
DNA insert from DAS40278 (DAS-4Ø278-9) vector pDAS1740
The parental LMO was generated using the Whiskers-mediated transformation method. Sphingobium herbicidovorans aryloxyalkanoate dioxygenase-1 (aad-1) is under the control of Zea mays ubiquitin gene promoter and Z. mays root preferential cationic peroxidase terminator. Elevated levels of transcription are expected to occur due to the constitutive nature of the ubiquitin promoter.

Note:
- The aad-1 coding sequence was optimized for expression in the plant.
- Southern blot analysis indicated that a single complete copy of the transformation cassette was stably integrated into the host genome at a single locus.
- No integration of the vector backbone occurred.
