Like any cultivated crop, sweet potatoes have been genetically modified by humans over a very long period of time, through selective breeding, to produce improved varieties with desirable traits for flavor, texture, color, shape, pest and disease resistance, drought tolerance, and so on.
Do sweet potatoes exist in nature?
Sweet potatoes from all over the world naturally contain genes from the bacterium Agrobacterium, researchers report. Sweet potato is one of the most important food crops for human consumption in the world. Because of the presence of this “foreign” DNA, sweet potato can be seen as a “natural GMO,” the researchers say.
How was sweet potato created?
Sweet potato has been radiocarbon-dated in the Cook Islands to 1210–1400 CE. A common hypothesis is that a vine cutting was brought to central Polynesia by Polynesians who had traveled to South America and back, and spread from there across Polynesia to Easter Island, Hawaii and New Zealand.
Is sweet potato a hybrid food?
Researchers from Ghent University and the International Potato Institute have discovered that sweet potatoes from all over the world naturally contain genes from the bacterium Agrobacterium. Because of the presence of this ‘foreign’ DNA, sweet potato can be seen as a ‘natural genetically modified organism (GMO)’.
Where do sweet potatoes originally come from?
The earliest cultivation records of the sweet potato date to 750 BCE in Peru, although archeological evidence shows cultivation of the sweet potato might have begun around 2500-1850 BCE.
Are sweet potatoes a hybrid vegetable?
Not only that, but sweet potato plants actively express some of these genes. In light of this discovery, sweet potatoes serve as the first known example of a naturally transgenic food crop.
How can you tell if a potato is genetically modified?
There is no definitive way to tell if a potato has been genetically modified by looking at it. GMO White Russet potatoes can be identified by their branded bags with language such as “reduced bruising” and “fewer black spots,” but they may also be found in prepared and processed foods.

Who created sweet potato?
Sweet potatoes originated in Central and South America. But archaeologists have found prehistoric remnants of sweet potato in Polynesia from about A.D. 1000 to A.D. 1100, according to radiocarbon dating. They’ve hypothesized that those ancient samples came from the western coast of South America.
