>One example of hybridization between GM crops and wild species has been documented in creeping bentgrass commonly used on golf courses. Scotts Miracle-Gro genetically engineered this grass to contain a gene that confers resistance to a common herbicide so that the golf course can be sprayed to kill weeds without harm to the grass. Because this grass is wind-pollinated, a perennial, and highly capable of outcrossing with related wild species, researchers decided to investigate wild grass in close proximity for the presence of the herbicide resistance gene. The researchers collected seeds from wild plants at varied distances from the origin of the grass farm and used herbicides to detect tolerant plants. They confirmed the presence of the herbicide resistant gene in wild grass up to 9 miles from its origin only one year after the grass was planted [2,3,4]. This distance is very surprising because most hybridization events have been reported between plants that are less than a mile apart. It is clear from this study that genetic modifications can be transferred to wild species through hybridization; however, future investigations will need to be performed in order to differentiate whether the genetic modification increases the fitness of wild species or if these hybridizations are a natural result of planting a large grass farm in close proximity to wild species. https://sitn.hms.harvard.edu/flash/2015/challenging-evolution-how-gmos-can-influence-genetic-diversity/ https://sitn.hms.harvard.edu/flash/2015/challenging-evolutio...
