Abstract
Accelerator mass spectrometry (AMS) is an accelerator-based microanalysis technique with extremely high sensitivity. AMS can detect very rare isotopes, especially long-lived radioisotopes. One excellent application of AMS is in tracer experiments in biomedical samples. A recent study on aluminum transport has introduced the AMS method for the microanalysis of eluted aluminum in plant roots that had been exposed to A1.
To investigate the movement of such a small amount of Al at intracellular organelle levels, we developed a 26Al tracer technique with AMS and investigated Al accumulation in the leaf subcellular organelles after Al3+ had been absorbed by the roots and transported from roots to shoots. The investigation was carried out after Al3+ had absorbed by roots and transported to leaves in ruzigrass, an Al-tolerant plant, and barley, Al sensitive plant.
