Jan 6, 2022 · The oomycete Phytophthora infestans causes late blight disease in potato. This biotrophic pathogen invades living plant cells to obtain nutrients through the release of certain proteins, such as extracellular toxins, hydrolytic enzymes, and effectors.

May 16, 2022 · The use of Rpi genes recognizing conservative, essential effectors of P. infestans and the construction of Rpi gene pyramids may help to achieve durable, broad-spectrum late blight resistance, which could be accelerated through genetic engineering.
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.
Various Solanum species have been utilized as a source of resistance genes to combat late blight disease. Several potential resistance genes and quantitative resistance loci (QRLs) have been identified and mapped through the application of molecular techniques.
Feb 27, 2020 · According to Magembe, results from field trials conducted by the National Agricultural Organization (NARO) in Uganda showed that bioengineered (genetically engineered) potatoes could be cultivated without use of fungicides, while non-bioengineered potatoes were rapidly killed by late blight disease.
The use of Rpi genes recognizing conservative, essential effectors of P. infestans and the construction of Rpi gene pyramids may help to achieve durable, broad-spectrum late blight resistance, which could be accelerated through genetic engineering.
Jan 2, 2021 · Current genetically modified and gene edited varieties include those with Colorado potato beetle and late blight resistance, reduction in acrylamide, and modified starch content.
