Gene
The maize (Zea mays) was modified for resistance to insects and tolerance to herbicides. For resistance to Lepidopteran pests, the modified maize expresses a Bacillus thuringiensis chimeric delta endo-toxin Cry1Da2, which forms non-specific, ion conducting pores in the apical membrane of the midgut epithelial cells and leads to larval death. For tolerance to glyphosate, the modified maize expresses Streptomyces sviceus DGT28 5-enolpiruvilshikimate- 3-phosphate synthase, which allows for the continuing functioning of the shikimate pathway by avoiding inhibition from the herbicidal compound.
