Zusammenfassung:Synchrotron μ-XRF and autoradiography complementally revealed the different behavior of arsenic and phosphorus in Pteris vittata L. at a high spatial resolution in its living state. We found that P. vittata develops several sequestration mechanisms for As from important biological functions at different growth stages. Some of them relate to the activities in the roots of the sporophyte and the reproduction on the gametophyte.
