GmoDetector: An accurate and efficient GMO identification approach and its applications

Area of Science:

• Agricultural Biotechnology
• Molecular Biology
• Food Safety

Background:

• Increasing prevalence of genetically modified organisms (GMOs) in food and feed supply chains.
• Challenges in current GMO detection methods due to donor microorganism contamination.
• Need for sensitive and reliable detection of both authorized and unauthorized GMOs (UGMOs).

Purpose of the Study:

• To develop a high-throughput and contamination-removal method for GMO detection.
• To create a tool capable of identifying a wide range of transgenic elements and GMO events.
• To ensure accurate detection of GMOs in various food and feed matrices.

Main Methods:

• Development of GmoDetector, a novel GMO detection approach.
• Utilizing next-generation sequencing (NGS) combined with target enrichment technology.
• Targeting 64 common transgenic elements and 76 GMO-specific events from 251 GM events.

Main Results:

• GmoDetector effectively excludes donor microorganism contamination.
• Successful detection of both authorized and unauthorized GMOs (UGMOs) in processed and unprocessed food/feed.
• Achieved a sensitivity as low as 0.1% GMO content, meeting global labeling thresholds.

Conclusions:

• GmoDetector is a robust and efficient tool for GMO detection.
• The method provides accurate identification of authorized and unauthorized GMOs.
• GmoDetector addresses current limitations in GMO detection, enhancing food safety and regulatory compliance.
