Figure 5
Tomographic time series of the segmented maize root system showing the evolution of local D2O concentration in the root system reflecting water uptake and axial transport by individual roots. (a) Reference image taken six minutes after D2O infiltration, when the soil water distribution had become stagnant. The soil water (H2O) accumulation is displayed as blue cloudy structure. The soil region underneath is interfused with deuterated water (transparent). (b–e) Development of D2O concentration in the tissue of the individual roots. The time resolution for each tomogram is 2 min. A video of this sequence is provided in the supplementary information.
