eldavojohn writes "A research team conducting a survey has found that about 86% of wild canola plants in North Dakota have genetically modified genes in them, and 'two samples contained multiple genes from different species of genetically modified plants.' Canola usually has little competition when cultivated but does not fare well in the wild. The Roundup Ready and Liberty Link strains of genetically modified canola appear to be crossing over to wild plants and helping it survive. The University of Arkansas team claims that the ease in which genetically modified canola has 'escaped' into the wild should be noted by seed makers like Monsanto because this is proof that it will happen."
Reader n4djs notes that Monsanto has been known to sue farmers for patent infringement when their crops unintentionally contain genetically modified plants.
