Naturally Genetically Modified Sweet Potato
Found to Naturally Contain Genes from Bacteria

Whoops. It may come as a shock to some people but genetically modified (GM) crops are not just created by humans, but also occur naturally. A news report in the 23 April 2015 Nature (pg. 410) reports on the discovery of a sweet potato cultivar that had apparently been infected by Agrobacterium bacteria in the past. These bacteria infect plants and transfer DNA into their host’s genome, which is how the genes ended up in the sweet potato. (In fact, modern genetic engineering commonly uses these bacteria as vehicles to transfer genes into plants they want to genetically modify.) The original paper on this subject was published in the Proceedings of The National Academy of Sciences,2 in which the authors concluded, “This finding could influence the public’s current perception that transgenic crops are ‘unnatural.’”
