Notice of submission from Bayer CropScience Inc. and KWS SAAT SE & Co. KGaA for novel food, livestock feed and environmental safety approval for commercial planting purposes of a plant genetically modified for herbicide tolerance
The Canadian Food Inspection Agency (CFIA) and Health Canada have received a submission from Bayer CropScience Inc. and KWS SAAT SE & Co. KGaA seeking an environmental safety approval for commercial planting purposes and livestock feed and food use of a sugar beet line designated as KWS20-1, which has been genetically modified to exhibit herbicide tolerance. 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 BIO2023-01: The Biology of Beta vulgaris L. (Sugar Beet).
Description of the modification
Sugar beet line KWS20-1 was developed through the use of recombinant DNA technology. To assess the modification process, the following has been submitted:
- Characterization of the transformation system/modification process
- Description of the transformation method
- Nature and source of the carrier DNA
- Description of the genetic material delivered to the plant
- Components of the vector
- Summary of all genetic components
- Description of the inserted genes – dmo, pat and cp4 epsps
- Description of the promoters and terminators
- Portion and size of the inserted sequence
- Location, order and orientation in the vector
- Function of the genetic sequences in the plant
- Source of the dmo, pat, and cp4 epsps genes (donor organisms)
- Level of expression of dicamba mono-oxygenase (DMO), phosphinothricin N-acetyltransferase (PAT) and 5‑enolpyruvylshikimate‑3‑phosphate synthase (CP4 EPSPS) in roots and tops
- Review of the absence of toxicity and pathogenic ability of the genetic components to plants and other organisms
- Review of the absence of toxicity and pathogenic ability of the donor organisms to plants and other organisms
- History of use of the dmo, pat and cp4 epsps genes
- Detailed map of the vector
Inheritance and stability of the introduced trait
To assess the stability of the genetic modification the following has been submitted:
- Analysis of stability over multiple generations
To assess the inheritance of the genetic modification the following has been submitted:
- Analysis of segregation from one generation
Description of the novel traits
To characterize the DNA inserted in the plant, the following has been submitted:
- Information for all coding areas
- Information on plant promoters
- DNA analysis for introns, terminators and enhancers of plant expressible cassette
- Information on non-coding regions that have no known plant function and are not associated with expression of coding regions: DNA analysis for known function
- Characterization of DMO, PAT and CP4 EPSPS proteins in sugar beet tissues
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 either submitted or previously submitted, reviewed, and published:
- Bioinformatics evaluation of the DMO, PAT and CP4 EPSPS proteins
- Heat stability of the DMO, PAT and CP4 EPSPS proteins
- Digestibility of the DMO, PAT and CP4 EPSPS proteins
Nutritional evaluation of the novel plant
To assess nutritional aspects of the novel plant the following has been submitted:
- The nutritional composition of the novel plant has been compared to unmodified soybean. The following have been considered:
- Proximate composition (protein, fat, ash, carbohydrates)
- Composition of amino acids and minerals
- Crude fiber, pectin and root sucrose
- Secondary metabolites
To assess allergenicity and toxicity of the expressed genetic components the following has been submitted:
- Analysis of the amino acid sequence similarity of the DMO, PAT and CP4 EPSPS proteins to known protein allergens or toxins through bioinformatics analysis.
Evaluation of the environmental impact of the novel plant
To assess the environmental impact of the novel plant information addressing the following has been submitted:
- Potential of the PNT to become a weed of agriculture or be invasive of natural habitats
- Potential for gene flow to sexually compatible plants whose hybrid offspring may become more weedy or more invasive
- Potential of the PNT to become a plant pest
- Potential impact of the PNT or its gene products on non-target species, including humans
- Potential impact on biodiversity
- Herbicide tolerance management plan
