- British scientists have developed genetically modified potatoes that are resistant to the vegetable's biggest threat - blight. A three-year trial has shown that these potatoes can thrive despite being exposed to late onset blight. That disease has plagued farmers for generations and it triggered the Irish potato famine in the 1840s.

Oct 20, 2022 · Late blight, caused by Phytophthora infestans, is the most devastating disease in potato production. Here, we show full late blight resistance in a location with a genetically diverse pathogen population with the use of GM potato stacked with three resistance (R) genes over three seasons.
Jan 6, 2022 · For instance, the potato varieties Bionica and Toluca are resistant to late blight because they carry the Rpi-blb2 gene of S. bulbocastanum, but its development took more than 50 years. 19,27 Using genetic engineering approaches

Feb 27, 2020 · “The conventional varieties farmers have need to be sprayed up to 15 times with fungicides against late blight and other diseases,” Magembe said. “The bioengineered potato doesn’t need any spraying. It is completely resistant to the disease, which means zero pesticide use. This will increase the incomes of the resource-poor farmers.”

Internal potato tuber symptoms of late blight. Note that areas are rust to dark brown in color and remain firm and grainy in texture. When symptoms progress, secondary soft-rotting pathogens often invade. Rapid repetition of the asexual cycle causes large-scale late blight epidemics.
Dec 5, 2019 · A genetically modified potato with improved tuber quality and resistance to the devastating disease late blight has progressed successfully through the latest stage of trials.
