Researchers report a rice strain in which the grains' aleurone layer, which contains nutrients such as proteins, lipids, dietary fiber, and micronutrients, was thicker than in traditional rice cultivars, resulting in improved nutritional content; mutation in a gene encoding a DNA demethylation enzyme, OsROS1, was found to underlie the thickened aleurone, suggesting a potential strategy for improving the nutritional value of rice and other cereal crops.
