Notice of submission from Pioneer Hi-Bred Canada for novel food, livestock feed and environmental safety approval for commercial planting purposes of a plant genetically modified for herbicide tolerance and insect resistance
Background
The Canadian Food Inspection Agency (CFIA) and Health Canada have received a submission from Pioneer Hi-Bred Canada Company seeking an environmental safety approval for commercial planting purposes and livestock feed and food use of a maize line designated as DP51291, which has been genetically modified to exhibit herbicide tolerance and protection from targeted lepidopteran pests. The submission received is in accordance with CFIA guidelines for assessment of plants with novel traits for unconfined release and novel animal feeds, as well as Health Canada guidelines for assessment of novel foods.
Summary of the submission package
Updated scientific information may be added to this submission by the developer at a later date, or CFIA and/or Health Canada may request further information from the developer.
Description of the host plant
Please refer to Biology Document BIO2020-01: The Biology of Zea mays (L.) (Maize).
Description of the modification
Corn line DP51291 was developed through the use of recombinant DNA technology. To assess the modification process, the following has been submitted:
- Transformation method description and process
- Description of genetic elements used in the modification
- Description of the inserted genes, IPD072Aa, PAT and PMI
- Description of transformation, selection and breeding method
Inheritance and stability of the introduced trait
To assess the inheritance and stability of the genetic modification the following has been submitted:
- Mendelian inheritance of the novel traits
- Analysis of the stability of the novel traits over multiple generations
Description of the novel traits
To characterize the novel proteins produced in the plant, the following has been submitted:
- Mode of action of the IPD072Aa, PAT and PMI proteins
- Equivalence of the IPD072Aa, PAT and PMI proteins derived from DP51291 maize
- Levels of expression of IPD072Aa, PAT and PMI proteins in leaf, root, pollen, forage, and grain in DP51291 maize
Absence of toxicity of the novel gene products
To support the absence of toxicity of the expressed genetic components on non-target species, humans and animals, the following have been submitted or previously submitted, reviewed, or published:
- in silico toxicity evaluation of the IPD072Aa, PAT and PMI proteins
- Heat lability of the IPD072Aa, PAT and PMI proteins
- Digestibility of the IPD072Aa, PAT and PMI proteins protein in simulated gastric fluid
- Acute oral toxicity evaluation of the IPD072Aa, PAT and PMI proteins
Nutritional evaluation of the novel plant
To assess nutritional aspects the nutritional composition of the novel plant has been compared to unmodified maize. The following have been considered:
- Estimate of dietary exposure to IPD072Aa, PAT and PMI proteins in grain from DP51291 maize
- Generation of tissue samples for nutrient composition analysis
- Determination of nutrient composition analyte concentrations
- Proximates, fiber, and minerals in DP51291 maize forage
- Proximates, fiber in DP51291 maize grain
- Fatty acids, minerals, vitamins, secondary metabolites and anti-nutrients in maize grain
Allergenicity considerations
To assess allergenicity of the expressed genetic components, the following have been submitted or previously submitted, reviewed, or published:
- in silico allergenicity evaluation of IPD072Aa, PAT and PMI in DP51291 maize
Evaluation of the environmental impact of the novel plant
To assess the environmental impact of the novel plant, the following has been submitted:
- Germination and viability evaluation
- Evaluation of agronomic characteristics
- Field insect, disease, and abiotic stressor observations
- Weediness potential of DP51291 maize
- Agronomic performance and field observations conclusion

Public communications
The CFIA and Health Canada are seeking feedback or comments on the Notice of submission for DP51291. If you have a scientific question or any information that would be of value to CFIA and Health Canada evaluators in the assessment of DP51291, we encourage you to participate. Non-scientific input will also be evaluated and appropriate ways of addressing it will be explored.
Comments will not be responded to directly, unless CFIA requires more information. However, scientific questions or information you share will be forwarded to CFIA and Health Canada evaluators for consideration in the assessment. Non-scientific input will be evaluated and appropriate ways of addressing it will also be explored.
Additionally, subject to your consent, the CFIA will forward your comments to developers whose products are being assessed and may post them on the CFIA and Health Canada web sites. Developers will not be given your name or email, nor will any personal information be posted on the CFIA or Health Canada web site.
By way of submitting your comments, you acknowledge that Government of Canada officials and the developer may use your feedback in the assessment of DP51291.
We invite you to send us your comments by email or mail before August 13, 2023.
