GM Crops Food. 2025 Dec;16(1):1-10. doi: 10.1080/21645698.2024.2444048. Epub 2024 Dec 26.
The number of authorized genetically modified (GM) soybeans has increased worldwide. In Japan, 34 GM soybeans containing single events and their stacked varieties have been approved as food. However, not all approved GM events are commercially cultivated or distributed. In this study, we evaluated domestically distributed samples from the United States (US) and Canada using 17 event-specific detection methods for GM soybeans. Identity-preserved (IP) soybean samples imported from the US and Canada, and non-IP samples from the US in 2021 and 2022 were analyzed. Four GM soybean events consisting of MON89788, A5547-127, MON87708, and DAS-44406 were detected in all lots in the non-IP samples. Furthermore, a single-kernel-based analysis was conducted to determine whether the detected GM soybean events are stacked. The results suggest that DAS-44406 is rapidly increasing, particularly as a single event among GM soybeans.
全球范围内，获批的转基因大豆数量有所增加。在日本，34种含有单一事件及其叠加品种的转基因大豆已被批准用作食品。然而，并非所有获批的转基因事件都进行了商业化种植或销售。在本研究中，我们使用17种转基因大豆事件特异性检测方法，对来自美国和加拿大的国内销售样本进行了评估。分析了从美国和加拿大进口的身份保留（IP）大豆样本，以及2021年和2022年来自美国的非IP样本。在非IP样本的所有批次中均检测到由MON89788、A5547-127、MON87708和DAS-44406组成的四种转基因大豆事件。此外，还进行了基于单粒的分析，以确定检测到的转基因大豆事件是否为叠加事件。结果表明，DAS-44406正在迅速增加，尤其是作为转基因大豆中的单一事件。
