A stacked insect-resistant and herbicide-tolerant maize derived from conventional cross-breeding of DAS-Ø15Ø7-1 with DAS-59122-7.  Insect resistance is conferred by the cryIF, cry34Ab1 and cry35Ab1 genes from the common soil bacterium Bacillus thuringiensis, and glufosinate herbicide tolerance through the pat gene from Streptomyces viridochromogenes.
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.

Additional Information
Additional Information
Maize line TC1507 x DAS-59122 contains the cryIF gene from Bacillus thuringiensis subsp. kurstaki, which codes for a Bt-toxin, which protects the plant against the european corn borer (Ostrinia nubilalis) and other lepidopterans such as the pink borer (Sesamia spp.), fall armyworm (Spodoptera frugiperda), black cutworm (Agrotis ipsilon) and southwestern corn borer (Diatraea grandiosella), as well as cry34Ab1 and cry35Ab1 genes from Bacillus thuringiensis which protect the plant from the Coleopteran insects western corn rootworm (Diabrotica virgifera), northern corn rootworm (D. barberi), and Mexican corn rootworm (D. virgifera zeae).

This line also contains stacked tolerance to glufosinate ammonium containing herbicides, through incorporation of the pat gene from the soil bacterium Streptomyces viridochromogenes, which codes for the enzyme Phosphinothricin-Acetyltransferase (PAT) and leads to increased tolerance to glufosinate-containing herbicides.

This plant is a product of traditional plant breeding, and therefore is not automatically subject to regulation in all jurisdictions as are transgenic plants resulting from recombinant DNA technologies. Certain jurisdictions may request notification in advance of the release of a stacked hybrid, or may request information to conduct an environmental and food safety assessment.
