DNA insert from MON87411 vector PV-ZMIR10871
The MON87411 genome contains three cassettes: an RNA interference (RNAi) cassette targeting Diabrotica virgifera virgifera, Bacillus thuringiensis cry3Bb1 and Agrobacterium tumefaciens 5-enolpyruvylshikimate-3-phosphate synthase (cp4-epsps).

Transcription of the RNAi cassette commences from the Cauliflower mosaic virus 35S enhanced promoter and terminates at the Pisum sativum ribulose bisphosphate carboxylase small chain 2 terminator. The transcript initially contains a Zea mays heat shock protein 70 intron, which contributes to enhanced expression in vegetative tissues of the plant, and two partial coding sequences of the D. virgifera virgifera Snf7p gene, which encodes the SNF7 subunit of the ESCRT-III complex. The two Snf7p sequences are in an inverted orientation, separated by a 150-nucleotide intervening sequence, which allows base pairing between the inverted sequences and hairpin RNA formation post-transcription, which then triggers an RNAi response. Due to RNAi processing, small interfering RNA molecules (roughly 21-23 nucleotides in length) will be produced and thus no translation into protein will occur from this cassette.

Transcription of the cry3Bb1 is under control of the Z. mays physical impedance induced protein promoter and Triticum aestivum (wheat) heat shock protein 17.3 terminator. The transcript also contains a wheat 5' untranslated leader from chlorophyll a/b-binding protein and Oryza sativa actin 1 intron for enhanced expression of the transgene. Expression of cp4-epsps is under control of an O. sativa alpha tubulin promoter and terminator. The transcript additionally contains Arabidopsis thaliana chloroplast targeting peptide 2 to sequester the protein to the chloroplast.

Note:
- Sequencing, PCR and bioinformatic analyses indicate that a single, intact insertions of the three gene cassettes occurred in the parental line.
- No plasmid backbone was detected.

DNA insert from 59122 vector PHP17662:
Transcription of Bacillus thuringiensis cry34Ab1 starts at Zea mays ubiquitin gene promoter and terminates at the Solanum tuberosum proteinase inhibitor II gene terminator. Transcription of B. thuringiensis cry35Ab1 commences from the (Triticum aestivum (wheat) peroxidase gene promoter and stops at another S. tuberosum proteinase inhibitor II gene terminator.

Note:
- The coding sequence of cry34Ab1 and cry35Ab1 has been adapted to the codon usage in maize as to achieve optimal expression in planta.
- The cry34Ab1 and cry35Ab1 were cloned from B. thuringiensis strain PS149B1.
- Sequence analysis of 59122 done by the European Food Safety Authority indicated that this LMO contains one complete copy of the T-DNA of PHP17662 without internal rearrangements. All three gene cassettes, cry34Ab1, cry35Ab1 and pat, are intact within the transgenic event. The DNA sequences of the genes in 59122 are identical to those in the original plasmid except for two nucleotide differences in the wheat peroxidase promoter. At the 5' T-DNA end a deletion of 22 bp is observed and at the 3' T-DNA end a deletion of 25 bp is observed. The absence of vector backbone in maize 59122 was also demonstrated.
