Outline of Final Research Achievements

Our research via the use of unique genetic resources was carried out enable a holistic approach to profile the phytochemical composition as well as its related gene expression of alliums for functional material studies, through collaborative development of resources for metabolomics-high throughput chemical profiling by mass spectrometry, together with transcriptomics assay metadata by RNA-Seq. The metabolomics analysis of worldwide germplasm collection in garlic (Allium sativum L.) proved to be effective in evaluating its genetic diversity. Our main focus was to select useful food and/or medical materials amongst the mapping various genotypes and phenotypes. An omics approach could be utilized to characterize variation in these genetic stocks, developing capability and plant materials to support metabolomics-informed plant breeding studies.

Academic Significance and Societal Importance of the Research Achievements

中央アジアに由来する稔性系統を含む,我々の研究グループが保有するニンニク遺伝資源は世界各地から収集した変異に富むものである.本研究の成果により,これらの遺伝資源は数々の有用変異を有するバイオリソースとしてニンニクの遺伝学や育種に広く利用でき,重要な研究用リソースと成り得ることが証明された.特に,メタボローム解析を通じて,将来的に健康食材や医薬原料となる系統が見出されており,農業生産分野に止まらず広くライフサイエンス分野への科学的貢献が見込める成果として今後の研究の進展が期待される.
