What is Real-time imaging and analysis of differences in cadmium dynamics in rice cultivars ( Oryza sativa ) using positron-emitting^107^Cd tracer about?
## Background Rice is a major source of dietary intake of cadmium (Cd) for populations that consume rice as a staple food. Understanding how Cd is transported into grains through the whole plant body is necessary for reducing rice Cd concentrations to the lowest levels possible, to reduce the associated health risks. In this study, we have visualized and quantitatively analysed the real-time Cd dynamics from roots to grains in typical rice cultivars that differed in grain Cd concentrations. We used positron-emitting^107^Cd tracer and an innovative imaging technique, the positron-emitting tracer imaging system (PETIS). In particular, a new method for direct and real-time visualization of the Cd uptake by the roots in the culture was first realized in this work. ## Results Imaging and quantitative analyses revealed the different patterns in time-varying curves of Cd amounts in the roots of rice cultivars tested. Three low-Cd accumulating cultivars (__japonica__ type) showed rapid saturation curves, whereas three high-Cd accumulating cultivars (__indica__ type) were characterized by curves with a peak within 30 min after^107^Cd supplementation, and a subsequent steep decrease resultin
