Figure 1. Localization of Se, Zn and Ca in seeds of Se hyperaccumulators S. pinnata and A. biculcatus.

Figure 1

(a) Photograph of three seeds of S. pinnata (left) and three of A. bisulcatus (right) taken after synchrotron analysis. Note: at this time one of the A. bisulcatus seeds had shifted slightly toward the bottom left. (b) X-ray fluorescence (XRF) map showing Se distribution (in white) in the S. pinnata and A. bisulcatus seeds. (c) Tricolor-coded µXRF map of S. pinnata and A. bisulcatus seeds showing Se (in red), Zn (in green) and Ca (in blue). (d) Tricolor-coded µXRF map of S. pinnata and A. bisulcatus seeds showing Se (in red), Fe (in green) and K (in blue). The locations where XANES spectra were collected are indicated with numbered circles in panels B and C and results from XANES analyses are tabulated in Table 1.
