  • Title: Analysis of genetically modified organisms by pyrosequencing on a portable photodiode-based bioluminescence sequencer.
    Author: Song Q, Wei G, Zhou G.
    Journal: Food Chem; 2014 Jul 01; 154():78-83. PubMed ID: 24518318.
    Abstract:
    A portable bioluminescence analyser for detecting the DNA sequence of genetically modified organisms (GMOs) was developed by using a photodiode (PD) array. Pyrosequencing on eight genes (zSSIIb, Bt11 and Bt176 gene of genetically modified maize; Lectin, 35S-CTP4, CP4EPSPS, CaMV35S promoter and NOS terminator of the genetically modified Roundup ready soya) was successfully detected with this instrument. The corresponding limit of detection (LOD) was 0.01% with 35 PCR cycles. The maize and soya available from three different provenances in China were detected. The results indicate that pyrosequencing using the small size of the detector is a simple, inexpensive, and reliable way in a farm/field test of GMO analysis.
