同步辐射MU-XRF和放射自显影在高空间分辨率下互补地揭示了砷和磷在凤尾草生存状态下的不同行为。我们发现，在不同的生长阶段，P.vittata从重要的生物学功能中为As开发了几种隔离机制。其中一些与孢子体根部的活动和配子体上的繁殖有关。
Synchrotron mu-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.
