| Outline of Final Research Achievements |
NMR-based metabolic profiling was performed on rice plants grown under free air CO2 enrichment (FACE), elevated water-soil temperature (ET) and low nitrogen supply (LN). The effect of elevated CO2 was observed in Koshihikari at the panicle initiation stage. The PCA loading analyses suggested that the sugar composition changed in response to the increase of CO2. LN affected the amino acids, organic acid and sugar contents in Koshihikari after the heading stage. The effect of climate change in Takanari was smaller than Koshihikari. A modest changes in sugar composition was found in the leaf blade of Takanari at the heading stage. The effect of ET was not found in both Koshihikari and Takanari.
