Imaging and analysis of¹⁰⁷Cd transport into the panicle for Koshihikari and BIL48. BIL48 carries the QTL responsible for high Cd accumulation derived from Jarjan with the Koshihikari genetic background. (a) Photograph of test plants. The large dotted rectangle indicates the FOV of PETIS. (b) Serial images of Cd accumulation in the panicle (0-36 h). (c) Time course of Cd amounts in ROI-3 (neck nodes of panicles). (d) Time course of Cd amounts in ROI-4 (panicles). The Cd in ROI-4 refers to the Cd amount per glumous number. The relevant portion of each ROI is surrounded by red lines in the black and white photographs. Cd in ROI-3(pmol) and Cd in ROI-4(pmol) in Figure 4 indicate the sums of radioactive¹⁰⁷Cd and nonradioactive Cd.
