| Outline of Final Research Achievements |
Green stem disorder (GSD) causes a serious problem in the soybean harvesting because seed coat surfaces are soiled and its quality is deteriorated during machine harvesting. The metabolite- and element-compositions in the stems of soybean RILs with different GSD sensitivity were examined using the metabolomics and ionomics technique to evaluate the relationship between the genetical traits and physiological mechanism of GSD insensitivity. In the sensitive RIL to GSD, the amino acid and organic acid metabolism were activated, results in the increase of nitrogen content of stems. It was suggested GSD was activated the nitrogen metabolism because the increase of the amount of translocation of the element to the stems, not to seeds.
