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.
