April 15, 2012
Comment on this submission by: 2012-07-03


The Canadian Food Inspection Agency (CFIA) and Health Canada (HC) have received a submission from Okanagan Specialty Fruits Inc., seeking approval for unconfined environmental release for commercial planting purposes, livestock feed and food use for apple (Malus x domestica) events GD743 and GS784, which have been genetically engineered to be non-browning. The submission received is in accordance with CFIAguidelines for assessment of plants with novel traits (PNTs) for unconfined release, CFIAguidelines for assessment of novel feeds from plant sources, and HC guidelines for assessment of novel foods. To view information related to the environmental assessment of a PNT or a novel feed, please refer to the CFIA Web site. To view the information related to the health and safety assessment of a novel food, please refer to the HC Web site.

Summary of the Submission

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 The Biology document “The Biology of Cultivated Apple” is being prepared by the Plant Biotechnology and Risk Assessment Unit of the CFIA.
Description of the Modification The PNT was developed through recombinant DNAtechnology. In order to assess the novel trait, the following was submitted:

  • Rationale for development of non-browning apples
  • Description of the transformation system
  • Biology of polyphenol oxidase (PPO)
  • Components of the transformation vector
Inheritance and Stability of the Introduced Trait In order to assess the inheritance and stability of the genetic modification, the following has been submitted:

  • Mendelian inheritance of the insert
  • Clonal stability of the insert
Description of the Novel Trait In order to characterize the trait, the following has been submitted:

  • Characterization of the DNA insertion by PCR, Southern analysis and reverse primer PCR
  • Quantification of polyphenol oxidase (PPO) suppression by enzyme assay
  • Quantification of the effect of PPO suppression by controlled bruising experiments
Allergenicity/Toxicity Considerations In order to assess allergenicity of the novel trait the following has been submitted:

  • Analysis by NptII ELISA showing that NptII protein does not accumulate in mature apple fruit
  • Rationale that no new proteins are expressed in GD743 and GS784
  • Comparison of the amino acid sequence of putativeORF to known allergens
Nutritional Evaluation of the Novel Plant In order to assess the nutritional aspects of the novel plant the following has been submitted:

  • The nutritional composition of the novel plant has been compared to an unmodified apple. The following have been considered:
    • Proximate composition (e.g. ash, moisture, protein, fat, carbohydrates, calories and sugar profile)
    • Dietary fibre
    • Potassium
    • Vitamin C
    • Oxygen radical absorbance capacity (ORAC)
    • Phenolics
Evaluation of the Environmental Impact of the Novel Plant In order to assess the environmental impact of the novel plant, the following has been submitted:

  • Importance of apple, including production, cultivars, uses of apple, and apple nutrition
  • Economic impact of browning and current methods for inhibition of browning
  • Anticipated economic impact of GD743 and GS784
  • Gene flow and stewardship of GD743 and GS784
  • Agronomic and pest and disease data showing that GD743 and GS784 are equivalent to their untransformed parent cultivars
