Abstract

Gene flow from crops to related wild species must be considered when assessing the potential environmental impact of cultivating genetically modified plants1. Evidence of pollen dispersal within species has been found for several crops but little information is available on spontaneous gene flow from crops to related species with simultaneous flowering periods2,3. To study the genetic mechanisms involved, we have developed an intergeneric model of gene flow from transgenic oilseed rape (Brassica napus L.; genotype, AACC; diploid chromosome number, 2n=38) containing one copy of the bar gene, which confers resistance to the herbicide Basta (glufosinate ammonium), to wild radish (Raphanus raphanistrum L.; genotype, RrRr; 2n=18), a widely distributed weed.
