Outline of Final Research Achievements

In this study, we comprehensively analyzed how Al-accumulator woody plants adapt to aluminum (Al) stress by analyzing gene expression, element, metabolite, and Al-form mainly using Melastoma malabathricum (Melastoma). As a result, the whole aspect of gene expression related to Al absorption, transportation and accumulation in Melastoma, the importance of Al-citrate chelate in Al accumulation in leaves, and the importance of phenolics in Al accumulation of woody plants were clarified. The results obtained in this study will give many suggestions in future research on mechanisms of adaptation to excess Al / mechanisms of Al accumulation, in Al-accumulator woody plants.
