Rice Grain Quality & Climate Change


plant growth experiments

The lack of a single micronutrient (zinc) and presence of a single toxin (arsenic) in rice grain adversely impact the health of hundreds of millions of people. We are working to understand connections between climate conditions and concentrations of arsenic and zinc in rice gain. Climate change is expected to decrease rice yields, but its impact on the nutritional quality of rice grain is unknown. While human health depends on having enough food to eat, the nutritional quality of the food is equally important, particularly in developing countries where grain is the primary food source. Grain elemental composition depends on plant access to and uptake of elements from soil, and on translocation of these elements to grain. Availability, uptake and translocation of arsenic and zinc in rice plants are all punitively sensitive to climate conditions.
