Late blight caused the Irish Potato famine of the 19th Century. It results from infection by the fungal-like mould Phytophthora infestans, causing losses of $6B/ year for potato and tomato production.Potato is the fourth most important crop in the world and widely grown in Europe, USA, South America, Canada, China, India and Africa.Potato is easy to modify using strains of nature’s genetic engineer the bacterium Agrobacterium tumefaciens which transfers specific genes into cells of potato. Pieces of potato stem are used for making the genetically modified potato plants. Cells which have received the gene from the bacterium form a mass of undifferentiated cells, or callus, on ...
Traditional breeding techniques have failed to produce varieties that have durable resistance to late blight. This is because they have tended to introduce resistance genes one at a time which are easily overcome by the pathogen. Professor Jonathan Jones says: “If you put in three effective genes at once they are all in effect saving each other bec...
Bruising causes millions of potatoes to be thrown away every year. Maris Piper lines used in these trials have a gene switched off, or silenced, which makes the tuber less prone to bruising and ensure that the potato meets customer quality specifications. “There is a lot of wastage from bruising. Potato harvest is in September/October so to ensure ...
May 18, 2018 · The paper has been published in the European Journal of Agronomy. 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.
Jan 6, 2022 · These problems can be addressed by genetic modification (GM) or gene editing (GE) and open a wide horizon for potato crop improvement. Current genetically modified and gene edited varieties include those with Colorado potato beetle and late blight resistance, reduction in acrylamide, and modified starch content.

Apr 22, 2021 · Farmers of the future face a big challenge: feeding Earth's expanding population while minimising environmental impacts and keeping food affordable. One solution is genetically modified (or GM) crops. Read on as we examine what food that can be genetically modified, how they can be improved, and why people worry about GM foods.
May 26, 2020 · The 100-plus wild species relatives of potato provide a virtually endless source of traits that can be incorporated into elite varieties relatively easily and quickly.
