A team led by Prof. Liu Chunming at the Institute of Crop Sciences of CAAS published an article titled "Mutations in the DNA demethylase OsROS1 result in a thickened aleurone and improved nutritional value in rice grains" in Proceedings of the National Academy of Sciences. This study discovered a novel way to improve the nutritional value of rice through identification of thick aleurone mutants, which provides genetic materials for developing nutrient-dense rice and possibly other cereals as well.
Mutation of the OsROS1gene led to a general improvement of nutritional profile in rice
