Maize 1507 x NK603


Trait: Resistance to lepidopteran pests, and tolerance to glufosinate ammonium and glyphosate containing herbicides.
Inserted gene (1507):
cryIF-gene

Source: Bacillus thuringiensis kurstaki

Function: The gene 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).

Inserted gene (NK603):
cp4 epsps- gene

Source: Soil bacterium Agrobacterium ssp. strain CP4

Function: The cp4 epsps gene encodes for a version of EPSPS that is highly tolerant to inhibition by glyphosate and therefore leads to increased tolerance to glyphosate-containing herbicides.

pat-gene Source: Soil bacterium (Streptomyces viridochromogenes)

Function: The pat gene codes for the enzyme Phosphinothricin-Acetyltransferase (PAT) and leads to increased tolerance to glufosinate-containing herbicides.

Methods for the genetic modification: Microparticle bombardment of plant cells tissue.
