In situ L-edge XANES spectra obtained for nine standard compounds and the selected plant samples obtained using synchrotron-based XAS. Data are presented for buckwheat (Xiqiao-2) and Arabidopsis (Col-0) exposed to Al for 48 h. 50Sat is 50% saturation, 100Sat is 100% saturation and 150Sat is 150% saturation. TFY = total fluorescence yield. |
