Pamela Ronald studies the genes that make plants more resistant to disease and stress. In an eye-opening talk, she describes her decade-long quest to help create a variety of rice that can survive prolonged flooding. She shows how the genetic improvement of seeds saved the Hawaiian papaya crop in the 1990s — and makes the case that modern genetics is sometimes the most effective method to enhance food security for our planet’s growing population.
