The Info List - Arctic Apples

--- Advertisement ---

Arctic® apples are a group of trademarked apples that contain a nonbrowning trait (when the apples are subjected to mechanical damage, such as slicing or bruising, the apple flesh remains as its original color)[1][2] introduced through biotechnology. They were developed through a process of genetic engineering by Okanagan Specialty Fruits Inc.[3][4] Specifically, gene silencing reduces the expression of polyphenol oxidase (PPO), thus preventing the fruit from browning.[5] It is the first genetically engineered apple to be approved for commercial sale, though Innate potato varieties that were improved through biotechnology have also been approved for sale in the United States.[6] Developing nonbrowning Arctic® apples relies upon a technique called RNA-interference (RNAi).[7] This approach enables silencing of PPO expression to less than 10% of its normal expression, but does not change other aspects of the apple.[8] The RNAi process is accomplished through the use of a transgene that uses gene sequences that control PPO production.[2] Promoter and terminator gene sequences are used to support the implementation of PPO suppression genes, as is a marker gene which produces a protein (called NPTII) that makes the plant tissue resistant to the antibiotic kanamycin, allowing transformed plants to metabolize neomycin and kanamycin antibiotics.[9] This step is used to confirm that silencing PPO was successful.[8] Okanagan Specialty Fruits successfully petitioned for regulatory approval for two apple varieties in Canada from the Canadian Food Inspection Agency and Health Canada[10] and in the US from the Animal and Plant Health Inspection Service (APHIS), part of the United States Department of Agriculture.[2] Varieties that have received U.S. approval include Arctic® Golden (called GD743) and Arctic® Granny (GS784) in 2015,[11] and Arctic® Fuji (NF872) in 2016.[12] Arctic® Golden and Arctic® Granny varieties were both approved in Canada in 2015[13]. The Arctic® Fuji (NF872) was approved in Canada in 2018.[14] As of late 2017, the Arctic® Golden variety began retail sales as packaged, preservative-free apple slices.[15] Packaging bears Arctic® branding including their "snowflake" logo[16] and a QR code

that can be scanned with a smartphone to inform consumers about the safety and non-browning benefits via the company website.[17] Approval of the apple was opposed by GE Free BC and the Canadian Biotechnology
Action Network.[18] References[edit]
