Abstract:

Current techniques for detecting genetically modified (GM)rice primarily rely on conventional PCR, with no high-throughput, rapid screening methods available. This study used matrix assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) to create a multiplex primer panel for detecting multiple targets in GM rice. This method covers five target elements: the TT51 rice transformant-specific sequence, the Cry1A gene, the bar gene, theCaMV 35S promoter and the NOS terminator. The minimum detection limit for target genes was 0.5%. The established detection method offers high-throughput, multi-target capability, strong specificity and high sensitivity, offerring robust technical support for safety regulation, identity authentication and traceability management of genetically modified rice.

Key words: transgenic detection, nucleic acid mass spectrometry, rice transformant-specific sequences, exogenous genes
