Outline of Final Research Achievements

Imaging mass spectroscopy technique was used to map spacial distribution of metabolites, sugars, lipids and proteins on a thin slice of animal tissues, but it was very difficult to apply to the plant tissue analysis. In this study, the hardware and software was implemented to enable to map spacial distribution of metabolites, sugars and lipids on a intact plant tissue, not only on a thin sliced tissue, The special software to pick up the spacial distributions of the ions from several hundreds giga bytes of the data produced by the imaging mass spectroscope was also successfully developed.
