article_snippet.sent: The remarkable finding of ‘foreign DNA’ in the vegetable shows that The remarkable finding of ‘foreign DNA’ in the vegetable contains a type of natural genetically modified organism (GMO).
article_snippet.sent: It is not the first instance of natural GMOs to be found, but It is the first in sweet potatoes - a major crop plant.
article_snippet.sent: And the researchers say sweet potatoes all over the world contain this genetic modification.
article_snippet.sent: In comparison to "natural" GMOs, that are beyond we control, human-made GMOs have the advantage that we know exactly which characteristic we add to the plant,’ said Dr Gheysen.
