中文摘要：加拿大是世界上最大的亚麻生产国和出口国。2009年，在出口欧洲的加拿大亚麻中检测到了未经授权的转基因亚麻CDCTriffid的DNA，这导致了加拿大亚麻种植量的大量减少及出口市场的重大转变。对此，加拿大亚麻业进行了重大改革来确保从供应链中去除转基因亚麻。加拿大用RT-PCR检测方法对采收后的亚麻样品进行实验，以检测是否有转基因亚麻CDCTriffid的存在。本研究基于2009-2015年的更新数据，用先前描述的仿真模型重新评估了转基因亚麻在加拿大谷物市场的存在情况。此外，本文还研究了因亚麻生产和出口机会减少而导致的加拿大经济损失、主要亚麻品种重组的相关损失、及亚麻供应链中转基因亚麻的存在情况。
外文摘要：Canada is the world's largest producer and exporter of flaxseed. In 2009, DNA from deregistered genetically modified (GM) CDC Triffid was detected in a shipment of Canadian flaxseed exported to Europe, causing a large decrease in the amount of flax planted in Canada and a major shift in export markets. The flax industry in Canada undertook major changes to ensure the removal of transgenic flax from the supply chain. To demonstrate compliance, Canada adopted a protocol involving testing grain samples (post-harvest) using an RT-PCR test for the construct found in CDC Triffid. Efforts to remove the presence of GM flax from the value chain included reconstituting major flax varieties from GM-free plants. The reconstituted varieties represented the majority of planting seed in 2014. This study re-evaluates GM flax presence in Canadian grain stocks for an updated dataset (2009-2015) using a previously described simulation model to estimate low-level GM presence. Additionally, losses to the Canadian economy resulting from the reduction in flax production and export opportunities, costs associated with reconstituting major flax varieties, and testing for the presence of GM flax along the flax value chain are estimated.
