Outline of Final Research Achievements

Ionomic analysis, high-throughput elemental analysis, was performed in three diverse fruit crops to represent element concentrations in edible parts and to compare element concentrations between edible parts and vegetative organs and between species. Nineteen elements containing essential elements for human health, toxic elements, and elements with radioisotopes from nuclear reactors were analyzed in apple, Japanese pear, eggplant, and edamame. The distributions of elements were shown as basic information needed for biofortification, and high mobilities depending on species were found in some elements whose mobilities are believed to be low. Classification of element profiles into the leaf and the others containing the edible part except with the calyx in principal component analysis revealed the similarity in element distribution across the species. The present study may contribute to the research progress in the ionomics studies of fruit crops.
