The stacked maize line ACS-ZMØØ3-2 x MON-ØØ81Ø-6 was obtained through the traditional cross breading of each of the parental organisms to produce a maize that expresses each of PAT and Cry1Ab genes. The expression of these genes are expected to confer resistance to Lepidoptera, and tolerant to glufosinate herbicide.
Recipient Organism or Parental Organisms
The term Recipient organism refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas Parental organisms refers to those that were involved in cross breeding or cell fusion.

Notes regarding the genetic elements introduced or modified in this LMO
DNA insert from ACS-ZMØØ3-2 vector pDH51
Glufosinate tolerance in T25 maize due to the enzyme phosphinothricin-N-acetyltransferase (PAT). The PAT enzyme catalyzes the acetylation of phosphinothricin, detoxifying it into an inactive compound. Molecular analyses shows that it has a truncated copy of the bla gene (25% of the 5' end of the bla gene is missing in T25) and an intact Ori-pUC.

DNA insert from MON-ØØ81Ø-6 vector PV-ZMBK07 and PV-ZMGT10
MON810 contains a truncated portion of a synthetic form of the cry1Ab gene from Bacillus thuringiensis subsp. kurstaki. This confers resistance to Lepidoptera pests. Two constructs PV-ZMBK07 and PV-ZMGT10 were used for transformation, but molecular analyses showed no elements from the PV-ZMGT10 construct were integrated and only the elements from construct PV-ZMBK07 have been integrated into its genome. The terminator of the nopaline synthase (nos) gene was lost due to a truncation at the 3' end of the gene cassette during genome integration and is, therefore, not present in MON810.
