DNA insert from MON87427 (MON-87427-7) vector PV-ZMAP1043
Transcription of Agrobacterium tumefaciens 5-enolpyruvylshikimate-3-phosphate synthase (epsps) commences from the Cauliflower mosaic virus (CaMV) enhanced 35S promoter and terminates at the A. tumefaciens nopaline synthase (nos) terminator. The transcript contains a Zea mays heat shock protein 70 (hsp70) intron, an Arabidopsis thaliana N-terminal chloroplast transit peptide sequence for chloroplast targeting of the protein and 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 epsps coding sequence is the codon optimized coding sequence of the aroA gene from Agrobacterium sp. strain CP4 encoding EPSPS.


DNA insert from DAS40278 (DAS-4Ø278-9) vector pDAS1740
The 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.


Kindly refer to the parental  LMO records for more information.
