Serial images of ⁷⁴As behavior and time course of the amount of As in different regions of A. thaliana. (a) Photograph of test plant in the experimental apparatus. The solid red rectangles indicate the field of view of the PETIS during the plant imaging. (b) Serial images of the A. thaliana (0–168 h). Each frame was created from the integration of original images collected every 5 min. (c) Examined regions in the plant. The blue rectangle indicates the region of the solution, the purple rectangle indicates the solution with the roots inside, the yellow-green rectangle indicates the roots above the solution and the green rectangle indicates the shoots. (d) The time course of the amount of As in the regions shown in (c) fed with 0.2 μM AsV including 2 kBq of ⁷⁴As-labeled AsV.
