DNA insert from MON87460 vector PV-ZMAP595
The T-DNA insert contains the following gene cassettes: Bacillus subtillus cold shock protein (cspB) and Escherichia coli neomycin phosphotransferase II (nptII). 

Transcription of cspB is under control of the Oryza sativa actin 1 promoter and Agrobacterium tumefaciens transcript 7 gene 3' untranslated region. The transcript initially contains an O. sativa actin 1 intron for enhanced gene expression of cspB. The sequence is removed (spliced) prior to protein translation. Constitutive expression of cspB is expected due to the actin promoter.

Transcription of nptII is under control of the Cauliflower mosaic virus (CaMV) 35S promoter and A. tumefaciens nopaline synthase terminator. High levels of transcription are expected due to the CaMV promoter.

Note:
- The coding sequence of cspB has been codon optimized for optimal expression within plant cells.
- Southern blot analysis indicated that no vector backbone sequences were inserted into the parental genome
- Southern blot analysis indicated that the parental genome contains a single insertion
- Sequencing analyses confirm the Southern blot analyses.
- A 22 base pair deletion of genomic DNA at the insert-to-plant DNA junction occurred.
- loxP sites can be found in the parental genome and could potentially allow for the excision of the nptII cassette by CRE recombinase.

DNA insert from MON89034 vector PV-ZMIR245
Two insecticidal protein expression cassettes were inserted into the genome. Bacillus thuringiensis cry1A.105 expression is under the control of the CaMV 35S enhanced promoter, which first transcribes wheat (Triticum aestivum) 5' untranslated region of the chlorophyll a/b-binding protein (cab) and a rice actin 1 intron before transcribing cry1A.105. Transcription terminates at the wheat heat shock protein 17.3 terminator. Expression of the B. thuringiensis cry2Ab2 starts at the Figwort mosaic virus 34S promoter, which transcribes the Zea mays heat shock protein 70 (hsp70), then the Z. mays transit peptide and the cry2Ab2 coding sequence, before terminating at the nos terminator.

Note:
- The Cry2Ab2 coding sequence was modified for optimal expression in plants.
- South blot analysis confirmed that single insertions of both cry2Ab2 and cry1A.105, as well as no vector backbone were present and in the parent.
- A deletion removed the duplicated enhancer elements compared to the original CaMV 35S enhanced promoter in PV-ZMIR245.
- The selectable marker, nptII, cassette was bred out of the parental line and became not associated with this transformation event.

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.
