Introduction Expand

This stacked cotton 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 Gossypium hirsutum (Cotton) Expand

Center of Origin Reproduction Toxins Allergenicity

Believed to originate in Meso-America (Peruvian-Ecuadorian-Bolivian region).

Generally self-pollinating, but can be cross-pollinating in the presence of suitable insect pollinators (bees). In the U.S., compatible species include G. hirsutum, G. barbadense, and G. tomentosum.

Gossypol in cottonseed meal.

Cotton is not considered to be allergenic, although there are rare, anecdotal reports of allergic reactions in the literature.

Donor Organism Characteristics Expand

Latin Name Gene Pathogenicity
Bacillus thuringiensis subsp. kurstaki cry1Ac

Although target insects are susceptible to oral doses of Bt proteins, there is no evidence of toxic effects in laboratory mammals or bird given up to 10 µg protein / g body wt. There are no significant mammalian toxins or allergens associated with the host organism.

Bacillus thuringiensis subsp. kurstaki cry1Ab-Ac

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.

Agrobacterium tumefaciens strain CP4 CP4 epsps

Agrobacterium tumefaciens is a common soil bacterium that is responsible for causing crown gall disease in susceptible plants. There have been no reports of adverse effects on humans or animals.

Abstract Collapse

15985 X MON1445 (OECD identifier: MON-15985-7 x MON-Ø1445-2) cotton is the product of the cross-breeding of the insect-resistant cotton line 15985 (MON-15985-7) with the herbicide-tolerant cotton line MON1445 (OECD: MON-Ø1445-2). This stacked cotton line 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. Examples of jurisdictions that require either notification or information about stacked hybrids prior to their release into the environment, and for use in human food and livestock feed are Canada and Japan.

The stacked cotton line 15985 X MON1445 expresses three novel proteins: the delta-endotoxins Cry1Ac and Cry2Ab, both of which confer resistance to the lepidopteran pests of cotton, such as the cotton bollworm, pink bollworm and tobacco budworm, and the CP4 EPSPS protein which confers tolerance to the herbicide glyphosate. The insecticidal proteins Cry1Ac and Cry2Ab produced by the cry1Ac gene and cry2Ab genes respectively, both of which are from 15985. The CP4 EPSPS protein is produced by the cp4 epsps gene from MON1445. The novel traits of each parental line have been combined, through traditional plant breeding, to produce this new cotton line. For a full description of each parental line please refer to the individual product descriptions in the crop database for 15985 and MON1445.
The inserted genes and their gene products have a history of safe use, and have undergone review and approval by several regulatory agencies. No interactions among the gene products or negative synergistic effects are expected in the stacked hybrid. Since neither Cry1Ac, nor Cry2Ab are enzymes, these proteins have no effect on plant metabolism. The CP4 EPSPS has high affinity for its substrates phosphoenolpyruvate (PEP) and shikimate-3-phosphate, which are part of the shikimate metabolic pathway. CP4 EPSPS, Cry1Ac and Cry2Ab are therefore not expected to interact within, nor affect the metabolism of the stacked line.
Studies were conducted to compare the resistance to lepidopterans and tolerance to glyphosate between the stacked cotton line and each parental line. Results demonstrated that there were no significant differences in the stacked line in the resistance to the lepidopteran pests, or in the tolerance to applications of glyphosate, compared to the parental lines.
