Time course of the amount of zinc in different regions of dwarf rice plants. a Examined regions in the underground part of the plants. The blue dotted rectangle indicates the region of the solution and the red solid rectangle that of the solution and the root. b Time course of the amount of zinc in the solution. c Time course of the amount of newly acquired zinc in the root. e Examined regions of the above-ground part of the plants. d Time course of the amount of newly acquired zinc in the shoot base. f Time course of the amount of newly acquired zinc in the shoot base. g Time course of the amount of newly acquired zinc in the panicle. The dotted line indicates a linear approximation of the data. The red bar below the time axis represents the duration of the ⁶⁵Zn feeding step, during which 3 nmol of zinc were administered to the plants
