Dennis’s guest for this episode is David Spencer, a researcher in plant physiology and phytopathology in Germany. In his Ph.D., David uses genetic engineering to fortify soybeans against fungal infection. They explain why we need more resilient crops fast, why this would be great for the environment, and how genetic engineering can help achieve this.

The episode complements the previous one (extended throwback with Hélène Pidon) which focused on explaining different breeding methods and how artificially induced mutations compare to naturally occurring ones.

Plant geneticists are not happy with the European judgement on gene editing

Dr. Hélène Pidon is a postdoctoral researcher at the Leibniz Institute of Plant Genetics and Crop Plant Research. She searches for genes that give plants resistance to diseases. She wants to use these genes to fortify cultivated Barley against these diseases, and thus reduce the amount of pesticides used to grow the plant. When the European Court of Justice ruled on the status of crops modified with gene editing methods like CRISPR, Hélène contacted me to talk with me about GMO crops.
