(A) X-ray fluorescence (µXRF) map showing distribution of Se (in red), Ca (in green) and iron (in blue) in a cross-section of an A. bisulcatus taproot. (B) Se speciation in the tap root as determined by X-ray absorption near edge structure (XANES) spectroscopy at the locations indicated in panel A by circles. (C) Distribution of Se (in red), Ca (in green) and Zn (in pink) in a lateral root with nodule. (D) Sespeciation in the tip of the lateral root (locations shown as white circles in C).
