GMO Detection (35S, NOS, FMV) – Methods & Regulation
Learn how GMOs are detected via 35S, NOS, and FMV markers. Key methods, EU labeling rules, and consumer protection explained.
Things worth knowing about "GMO Detection"
GMO detection (genetically modified organisms) commonly relies on identifying specific promoter and terminator sequences inserted into transgenic plants.
The most widely used markers are the 35S promoter from cauliflower mosaic virus (CaMV), the NOS terminator from Agrobacterium tumefaciens, and the FMV promoter from figwort mosaic virus. These DNA elements serve as key indicators of genetic modification.
Detection is typically carried out using PCR-based methods, which are highly specific and sensitive. By identifying these sequences, laboratories can reliably determine whether a food or feed sample contains genetically modified material. This is especially important for imports from regions where GMO crops are widely cultivated.
Within the European Union, strict labeling regulations apply for products containing more than 0.9% genetically modified content. Therefore, testing for 35S, NOS, and FMV elements is a routine part of accredited laboratory controls, ensuring transparency and consumer protection.
