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 ...

Jan 6, 2022 · Introduction. Potato (Solanum tuberosum L.) is the third most important food for human consumption behind wheat and rice, and among the top horticultural crops. 1 Two thirds of the annual yield is marketed fresh, while the remainder is processed for snack and other industrial food products, including animal feed, adhesives, pharmaceuticals, wood, and textile commodities. 2,3 In 2019, 17.5 ...

Sep 14, 2022 · Potatoes (Solanum tuberosum) are one of the most important crops worldwide. However, its production and nutrient content are endangered by both biotic and abiotic stresses. The main yield losses are caused by pest damage (e.g., Colorado potato beetle and aphids), virus disease (e.g., Potato leafroll virus and Potato viruses Y and X), or oomycete pathogens (like Phytophthora infestans), which ...
