Introduction Expand

This stacked maize hybrid is a product of traditional plant breeding, and is therefore not automatically subject to regulation in all countries, unlike transgenic plants resulting from recombinant-DNA technologies. The approvals table above does not include entries from these countries. Other countries may request notification in advance of the release of a stacked hybrid, or may request information to conduct an environmental and food safety assessment, and these countries’ decisions are reflected in the approvals table.

Characteristics of Zea mays (Maize) Expand

Center of Origin Reproduction Toxins Allergenicity

Mesoamerican region, now Mexico and Central America

Cross-pollination via wind-borne pollen is limited, pollen viability is about 30 minutes. Hybridization reported with teosinte species and rarely with members of the genus Tripsacum.

No endogenous toxins or significant levels of antinutritional factors.

Although some reported cases of maize allergy, protein(s) responsible have not been identified.

Donor Organism Characteristics Expand

Latin Name Gene Pathogenicity
Bacillus thuringiensis subsp. kurstaki EC2.4.2.19

While target insects are susceptible to oral doses of Bt proteins, no evidence of toxic effects in laboratory mammals or birds given up to 10 µg protein/g body weight.

Streptomyces viridochromogenes pat

S. viridochromogenes is ubiquitous in the soil. It exhibits very slight antimicrobial activity, is inhibited by streptomycin, and there have been no reports of adverse affects on humans, animals, or plants.

Bacillus thuringiensis strain AB88 5AT

While target lepidopteran insects are susceptible to oral doses of VIP proteins, there is no evidence of toxic effects in laboratory mammals, in birds, and in non-target arthropods, including beneficial insects.
