The US Department of Agriculture's Animal and Plant Health Inspection Service (USDA APHIS) has exempted the genetically engineered Kal91.3 potato, developed by Michigan State University (MSU), from biotechnology regulations. This potato, bred by Prof Dave Douches, can be stored for long periods at low temperatures without sucrose, potentially reducing the need for fertilizers and pesticides. The potato was developed using RNA interference to silence the gene that produces an enzyme responsible for breaking down sucrose, improving storage stability and quality. This exemption marks the first for a genetically engineered vegetable developed by a land-grant university, opening up possibilities for its impact on the potato chip industry, particularly in Michigan, the eighth largest potato producer in the US.

A NEW genetically engineered potato will get to market faster in the United States by being granted exemption from the biotechnology regulations placed on genetically modified products. The Kal91.3 potato, bred Michigan State University (MSU) potato breeder Professor Dave Douches from an MSU potato variety named Kalkaska, can be stored in cool temperatures for long periods of time without sucrose, leading to healthier and higher-quality products, including potato chips. The Kal91.3 potato can also potentially reduce the environmental impact of the growing process without as many fertilisers and pesticides needed to maintain the potato during storage. The variety was granted exemption from the biotechnology regulations by the US Department of Agriculture's Animal and Plant Health Inspection Service (USDA APHIS). Sucrose, the compound that sugar is typically stored in potatoes as, is broken down in potatoes by vacuolar acid invertase, an enzyme reactive to the external environment ...
