Tiny gene edit cuts cadmium in rice by 48% without reducing yields

Article excerpt

Cadmium (Cd) contamination poses a serious threat to global food safety. As a toxic and carcinogenic heavy metal, cadmium can accumulate in agricultural soils through industrialization and urbanization before entering the human food chain. Rice is especially vulnerable because it absorbs more cadmium than other major cereal crops, making it one of the largest dietary sources of cadmium exposure for nearly half the world's population.
