Genetic Modification – Felipe Ricachenevsky

Getting enough iron from the food we eat is something most of us take for granted, but about 2 billion people worldwide have an iron deficiency, the Number 1 nutritional deficiency globally. An international research team led by scientists in Brazil have come up with a way to boost iron content in rice, which is one of the most consumed foods. Farm Table Talk talks with Dr. Felipe Ricachenevsky about research at the Federal University of Rio Grande do Sul in Brazil, where he is working to biofortify rice with higher iron and zinc content through genetic modification using CRISPR technology. Felipe explained that approximately 25-30% of the world population lacks sufficient iron and zinc in their diets, particularly affecting children in developing countries where rice is a staple food. He explains his lab’s approach of combining two iron transporters to achieve a 50-70% increase in iron concentration in rice grains, though this came with some trade-offs in waterlogged conditions. The discussion also covered the broader context of genetic modification, including the challenges faced by Golden Rice and how public perception shifted from accepting genetic improvements to opposing them when they were primarily used for pesticide-resistant crops. felipecruzalta@gmail.com
