Genotypic differences in shoot silicon concentration and the impact on grain arsenic concentration in rice

Silicon in rice ( Oryza sativa L.) has been demonstrated to be involved in resistance to lodging, drought, and salinity, and also enhances resistance to pests and diseases. The aim of this study was to determine the range of silicon concentration in a set of rice ( Oryza sativa L.) accessions, and to determine if the natural variation of shoot silicon is linked to the previously identified silicon transporters ( Lsi genes). Silicon concentration...
