| Outline of Final Research Achievements |
In this study, we aimed to integrate various physiological data from crops grown under field conditions by transcriptome and hormone analysis throughout their life-course, and to develop a basis for agri-data science to maximize crop productivity and sustainability through computational modeling. For this purpose, we investigated time series transcriptome and hormone datasets from a wild barley and a landrace accession, and revealed physiological changes along with their growth. We also analyzed genome-scale polymorphisms of diverse barley accessions. Moreover, using a legacy dataset of heading date of barely accessions and weather datasets, we developed statistical and/or machine learning-based models that estimate barely heading date.

| Academic Significance and Societal Importance of the Research Achievements |
地球規模の気候変動と人口の増加により食料供給は多様なリスクに直面している。農地の持続性と作物の生産性の両立が課題である。農地の生産性や持続性は、農地環境と作物の遺伝要因との相互作用によって決まる。本研究では、野外環境で栽培されているオオムギを材料として、栽培の初期から収穫期までの、遺伝子発現や植物ホルモンの状態を成長に沿って調査し、その動態と系統間の違いを明らかにした。また、オオムギの出穂時期を、遺伝子型や遺伝子発現等から推定する方法論の開発を行った。これらの成果は、そょうらいの気候変動に対して予見性をもった作物の育種等の基盤となる技術を提供するものと期待できる。
