Rice is the major food for half of the world population. The nutrition component in rice is critical for improvement of people’s health. Vitamin E serves as important antioxidant by quenching the free radical intermediates and thus protects the cell membrane. Because of the high nutritional value and the benefits of vitamin E in human health, increasing the tocochromanol content of major agricultural crops has long been in the focus of breeding programs and genetic engineering approaches. The key genes involved in tocopherol biosynthesis have been elucidated in Arabidopsis and other model organisms. Quantitative trait locus (QTL) study performed in Arabidopsis suggested that some of these key genes and a few additional loci contribute to natural tocopherol variations. Identifying such genetic variations in rice, enrich our understanding of the genetic mechanisms controlling tocopherol variation, which can be directly applied to rice breeding programs. In this study, we used genome-wide association mapping with high-resolution density SNPs of rice core set to identify natural allelic variations, which contribute to tocopherol increase in rice
