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 · By Michelle Starr. (Nastco/iStock) 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 · This review aims to highlight the current genetic engineering tools that are being employed in potato improvement, with special emphasis on varieties that have reached the market. It examines the traits that have been modified in potato, the methods used, and the final outcomes.

On the surface of it, his now-controversial research was perfectly straightforward: he fed genetically modified potatoes expressing a snowdrop lectin to rats and looked to see whether this food affected their physiology, particularly the gut, metabolic process and immune system.
Sep 14, 2022 · Because potatoes are an important commodity in the food and feed industry, there is growing pressure to adopt genetically modified plants that are tolerant to adverse conditions. Great development is also expected thanks to the new efficient genome editing tool (CRISPR/Cas9), which will make genetic transfection faster and more efficient than ...
Feb 17, 2014 · The blight-resistant GM potato was developed by scientists in the UK, including at The Sainsbury Laboratory, but it is unlikely to become commercially available in the UK any time soon, given restrictions around GM crops in the European Union.
