Potatoes are the No. 1 vegetable crop worldwide and the third most important human food crop, only behind rice and wheat in global production. Potatoes are grown in over 160 countries on 40.8 million acres and serve as a staple food for more than a billion people. With a medium-size potato supplying approximately 160 calories, mostly derived from s...
The amount of starch in potato tubers is the main factor that determines a potato’s use. High-starch potatoes are often used to make processed foods such as french fries, chips and dehydrated potatoes, Vales said. Potatoes with low to medium starch levels are frequently used for the fresh or table stock market, she said. For the fresh market, addit...
Developing potato cultivars with modified starch could open new opportunities, Toinga said. Potatoes with high amylopectin and low amylose, like the gene-edited Yukon Gold strain she described in the International Journal of Molecular Sciences, have industrial applications beyond traditional uses. In contrast, potatoes with high amylose levels and ...
CRISPR/Cas9 technology has expanded the toolset available to breeders, Vales said, and it represents a more direct, faster means to incorporate desired traits into popular commercial crop varieties. Conventional breeding is a lengthy process that can take 10-15 years. In addition, she said, due to the complex nature of the potato genome, generating...
Among the various potato cultivars evaluated in the first study, the Yukon Gold strain regenerated the best, and so it was used for the second study. In the second knockout study, described in the International Journal of Molecular Sciences, the native gene gbss in the tetraploid Yukon Gold strain was targeted to effectively eliminate amylose. The ...

May 18, 2018 · A potato variety genetically engineered to resist potato blight can help reduce the use of chemical fungicides by up to 90 percent, according to a new study - drastically reducing the environmental impact of potato farming.
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.
Dec 5, 2019 · The field trials follow successful lab experiments to modify Maris Piper potatoes with late blight resistance genes from wild relatives of potato called Solanum americanum and Solanum venturii.
