Preliminary investigation for plant science at Molecular Imaging Center

We have investigated of carbon nutrient dynamics in a higher plant by using a positron emission tomography, which is one of the most typical imaging apparatus installed at a Molecular Imaging Center in Medicine. Dynamic PET data of 11C activity distribution into root and soil was acquired quantitatively in intact plant body of soybean. This indicates that the three-dimensional photoassimilate translocation into the sink organs of underground was imaged successfully.
