| Outline of Final Research Achievements |
Rice phytolith is a highly persistent plant remains and is used to study about ancient rice cultivation. In the previous study, we developed a basic technique to recovery remained genetic information from inside of rice phytolith. However, some problems remained with the basic technique. Therefore, in this research, we improved for the following three agendas with practical applications and presented a new method to examine rice phytolith DNA. (1) Verification of the effectiveness of this technique for various sedimentary environments and soils of production residual soil. (2) Improvement of efficiency in extraction process of phytolith from the soil. (3) Verification of the practicality and effectiveness of this technique by a third party
As a result, it becomes clear that anyone who has basic experiment skills can recovery genetic information from rice phytolith extracted from paddy soil by using the method constructed in this research.

| Academic Significance and Societal Importance of the Research Achievements |
稲作の存否の検証に用いられるイネのプラント・オパールから遺伝情報が得られることにより、稲作史研究における限界の一つであった「時間と空間を網羅したイネ情報の整備」への道が拓かれたと言え、国内外の関連研究分野の進展に大きく貢献できる成果と言える。
また、本研究により復元される過去のイネの遺伝情報は、学術研究のみならず育種など農学部分野における社会実装にも繋がる可能性を有する成果でもある。
