No Escape for GM Pollen?
Little chance that genetic modifications to chloroplasts are transferred by pollen to wild plants.
Duration: 3 minutes, 29 seconds
Critics of genetically modified (GM) crops worry that herbicide resistance genes could be transferred to wild plants in pollen blown from a field of GM plants. Now researchers have shown that GM genes carried in maternally inherited chloroplasts are rarely transferred through pollen to other plants.
