Studies On Gene Flow From Herbicide-resistant Genetically Modified Rapeseed To Crucifers

Herbicide-resistant genetically modified crops (GMC) are being increasingly produced worldwide. A major concern about these releases is that transgene might flow from GMC to its wild relatives through pollen drift, which may cause certain ecological risks. Prior to commercialization of GMC, the assessment of the potential gene flow to the relatives is very necessary. Oilseed rape is one of the most important oil crops in the world; it belongs to the family of Cruciferae, genus Brassica. Cross-pollination and high cross-compatibility are frequently found in many cruciferous plants, which implies that there might be potential risk of alien gene flow among crucifers. In this work, the sexual compatibility between glyphosate-resistant GM rapeseed variety Q3 (Brassica napus L.) and 16 varieties from 15 cruciferous species was studied through fluorescence...
