Imaging and analysis of107Cd uptake by the roots of rice cultivars (vegetative stage). (a) Photograph of test plants. The large dotted rectangle indicates the FOV of PETIS. Nipponbare, Koshihikari, and Sasanishiki are of the japonica type, showing low Cd-accumulating cultivars. Choko-koku, Jarjan, and Anjana Dhan are of the indica type, showing high Cd-accumulating cultivars. (b) Serial images of Cd movement (0-36 h). (c) Time courses of Cd amounts in the roots surrounded by red lines in the black and white photograph. (d) Time course of Cd amounts in culture solution surrounded by red line. Cd in the roots (pmol) and Cd in solution (pmol) in Figure 1 indicate the sums of radioactive107Cd and nonradioactive Cd.
