Abstract:Arsenic (As) is naturally present in all soils and can accumulate to toxic levels in rice (Oryza sativa L.) grains under some production conditions. It can also reduce grain yields, posing a double threat to global food security. Plant genetics can affect the amount of As accumulated in grains. A growing body of evidence suggests that one mechanism plants use to detoxify As and limit As concentrations in grains (grain-As) is to sequester As in vegetative tissues. We evaluated 17 rice cultivars previously shown… Show more
