The study did use three different potatoes. There was a parent non-GMO potato, and two GM potato lines created from the parent. The two lines were produced at the same time, under the same conditions, using the same GNA lectin transgene.
In 2005, another group of scientists studied the effects of genetically modified potatoes on human health. Various potato clones were selected for this study where the cultivar and breeding lines had varying colors of flesh. The genetically modified cultivars had their composition of starch altered.
Árpád Pusztai is a Hungarian-born biochemist and nutritionist who spent 36 years at the Rowett Research Institute in Aberdeen, Scotland. He is a world expert on plant lectins, authoring 270 papers and three books on the subject. In 1998, Árpád Pusztai publicly announced that the results of his research showed feeding genetically modified potatoes to rats had negative effects on their stomach lining and immune system. This led to scientific criticism. Pusztai was suspended and his annual ...
Oct 31, 2018 · BELLINGHAM, WA — October 31 —The potato has been added to the High-Risk list of the Non-GMO Project Standard because a GMO potato variety is now “widely commercially available” in the United States. To determine when a crop needs to be moved from the Monitored-Risk list to the High-Risk list, the Project uses an established set of criteria related to the likelihood of GMO contamination in the conventional and non-GMO supply chain.
Apr 22, 2015 · It is not the first instance of natural GMOs to be found, but it is the first in sweet potatoes - a major crop plant. And the researchers say sweet potatoes all over the world contain this genetic ...

Ewen Mullins is the face of modern Ireland: Young, cosmopolitan, highly educated, he is a plant scientist whose work on a genetically modified potato inherently looks to the future. But Mullins also must think back to one of Ireland’s darkest chapters, the Great Famine of the 1840s.
This variety of potatoes is the one which was involved in the Pusztai affair. In 2014, a team of British scientists published a paper about three-year field trial showing that another genetically modified version of the Désirée cultivar can resist infection after exposure to late blight, one of the most serious diseases of potatoes. They developed this potato for blight resistance by inserting a gene (Rpi-vnt1.1), into the DNA of Désirée potatoes.
Nov 03, 2016 · The potatoes in question come from JR Simplot, a massive Idaho-based agricultural company probably best known as the biggest supplier of McDonald’s french fries. On November 2nd, the USDA approved two products in Simplot’s “Innate” line of GMO potatoes: the “Ranger Russet” and “Atlantic” varieties.
Genetically modified potatoes are on the way to market as of 2015. The U.S. government has deemed GM foods safe, but not all scientists agree. There is no legislation requiring the labeling of GMO foods, and critics worry about potential contamination of the conventional food supply and the safety of increased herbicide use.
