Supplementary Figure 14

Composite, 2D elemental concentration maps of wet, as cut thin sections of (a, d) wild type, (b, e) VIT1 and (c, f) IRT1 + FER1 cassava (a-c) stems and (d-f) storage roots. Relative concentrations of iron, zinc and calcium are represented as the intensity of red, green and blue respectively. The brightness has been scaled separately for each element, but is identical for each sample type. Scale bars at the lower left correspond to 1 mm. The color guide at mid-right illustrates the appearance of overlapping colors. In particular, yellow regions in (c) indicate strong co-localization of Fe and Zn in vascular bundles in IRT1 + FER1 stems.
