2015年4月21日 · 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...

2015年5月5日 · People have been farming — and eating — a GMO for thousands of years without knowing it. Scientists have found genes from bacteria in sweet potatoes around the world. So who made the GMO?

2015年4月22日 · The sweet-potato genome contains genes from bacteria, so is an example of a naturally occurring genetically modified (GM) plant.

2016年4月11日 · By any scientific definition of “gmo”, which entails an organism that contains nonendogenous gene sequences inserted via some means other that sexual reproduction, the sweet potato would be included.

2015年6月2日 · One of the world's most important staple crops, the sweet potato, is a naturally transgenic plant that was genetically modified thousands of years ago by a soil bacterium. This surprising...

2015年4月20日 · Simple and quantitative PCR, Southern blotting, genome walking, and bacterial artificial chromosome library screening and sequencing unambiguously demonstrated that two different T-DNA regions (IbT-DNA1 and IbT-DNA2) are present in the cultivated sweet potato (Ipomoea batatas [L.] Lam.) genome and that these foreign genes are expressed at ...

2015年11月27日 · Some 8,000 years ago a bacterium (Agrobacterium) inserted two of its genes into the original sweet potato DNA, thus producing a GM sweet potato. These genes have been detected in some 300 varieties of yam but are absent in close wild relatives; they are expressed and cause tissues like the root to swell.

2015年5月5日 · People have been farming — and eating — a GMO for thousands of years without knowing it. Scientists have found genes from bacteria in sweet potatoes around the world. So who made the GMO?

2021年12月20日 · Cassava (Manihot esculenta Crantz), sweetpotato (Ipomoea batatas) and yams (Dioscorea spp.) are important root and tuber crops grown for food, feed and various industrial applications. However, their genetic gain potentials are limited by breeding and genetic bottlenecks for improvement of many desired traits.

Those sweet potato varieties are not modern GMOs. They could, however, be natural GMOS. Scientists at the International Potato Center and the University of Ghent in Belgium discovered that all 291 sweet potato varieties they tested, and …
