Researchers at the University of Illinois have successfully engineered potatoes to be more resilient to global warming by adding two new genes, glycolate dehydrogenase and malate synthase, which increase the efficiency of photosynthesis. This modification has led to a 30% increase in tuber mass in hot conditions, as shown in field trials during a heat wave that hit the potatoes during the 2022 field season. The study, published in Global Change Biology, highlights the potential of improving photosynthesis to produce climate-ready crops without compromising nutritional quality.
