Michael Palmgren and colleagues at the University of Copenhagen coined the term "rewilding" to describe restoring useful properties that crops have lost during 10,000 years of domestication, such as tolerance to biotic and abiotic stresses. Precision breeding techniques now allow restoring genes responsible for these properties without introducing foreign DNA. However, rewilded crops may be considered GMOs in the EU due to the regulatory process, not the product. This could pose challenges to their approval and consumer acceptance, despite their potential to improve sustainability and food security. Palmgren is researching rewilded rice varieties with traditional nutrient levels to address malnutrition.
