A type of wild Cruciferae growing near a national highway in Mie Prefecture has been found to have genes of a genetically modified rapeseed, possibly a result of crossing between the wild plants and imported rapeseeds that had fallen during transportation, a survey by a civic group said Friday. [...] ”As the possibility that modified genes could spread among wildlife emerged, we are concerned that it could have an impact not only to farming products but also to ecosystems,” said Masaharu Kawata, a Yokkaichi University lecturer who was involved in the survey.
