Cadmium is known to pose severe risks to human health and thus is often studied by scientists. In some instances, researchers aim to decrease cadmium accumulation or improve the crops' ability to resist cadmium. Other researchers choose to study plants that can absorb cadmium in large quantities. These plants are studied for phytoremediation of cadmium in soil and water.
This study investigated the physiological and genetic mechanisms involved in Cd uptake in rice. The study suggests that an increase in ammonium nutrition can help reduce concentrations of cadmium in plants.
