Metabolite fingerprinting tools to detect differences between transgenic and conventional crops

Morin, Geneviève. January 2007 (has links)
A concern in transgenic crops is the potential risk posed by unintended effects which could result from genetic transformation. The objective of this work was to develop an untargeted approach that could characterize transgenic crops, as well as conventional crops, at the molecular level. An experimental approach was designed and used to compare conventional and transgenic soybean varieties. Varieties were compared using their metabolite fingerprints obtained by reverse-phase high performance liquid chromatography (HPLC) and both the analytical and biological variability were assessed. Multivariate and univariate statistical analyses were applied to the data to detect significant differences between the varieties. It was found that transgenic variety PS 46 RR was the most different variety analyzed and that it differed most from Mandarin (Ottawa) and AC Dundas. The statistical analyses also determined that PS 46 RR differed more from the conventional varieties tested than 2601R did.
