No Escape for GM Pollen?
Join commentators Dave Micklos and Jan Witkowski for a lively discussion of DNA in the news from world-renowned Cold Spring Harbor Laboratory! No Escape for GM Pollen? Little chance that genetic modifications to chloroplasts are transferred by pollen to wild plants. 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.
