DNA insert from MON87427 PV-ZMAP1043
Transcription of 5-enolpyruvylshikimate-3-phosphate synthase (cp4-epsps) from Agrobacterium tumefaciens commences from the Cauliflower mosaic virus (CaMV) enhanced 35S promoter and ends at the A. tumefaciens nopaline synthase (nos) gene terminator. The transcript contains a Zea mays heat shock protein 70 (hsp70) intron, Arabidopsis thaliana N-terminal chloroplast transit peptide sequence, and cp4-epsps.  The CaMV enhanced 35S promoter-hsp70 combination promotes gene expression in female and vegetative tissues, but not in male reproductive tissues (pollen microspores and tapetum).

Note:
- Southern blot analyses indicate that a single copy of the T-DNA was inserted at a single site in the parental maize genome and no plasmid vector backbone sequences were detected to have been integrated. DNA sequencing analyses further indicated that the expected T-DNA sequences were integrated.
- The cp4-epsps coding sequence is the codon optimized coding sequence of the aroA gene from Agrobacterium sp. strain CP4 encoding CP4 EPSPS.
- A second epsps cassette from the MON87411 promotes expression of epsps in all plant tissues (overcoming the tissue specificity from this parental genome).

DNA insert from MON87460 vector PV-ZMAP595
The T-DNA insert contains the following gene cassettes: Bacillius 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 TC1507 vector PHI8999A
DNA fragment PHI8999A contains two adjacent plant gene expression cassettes for Bacillus thuringiensis cry1F and Streptomyces viridochromogenes 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 the Cauliflower mosaic virus (CaMV) 35S promoter and ends at the CaMV 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 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.
