| Outline of Final Research Achievements |
In this study, I have investigated the gene expression profiles of Fd and FNR isoforms using Arabidopsis and rice plants. Gene expression profiles under elevated CO2 condition demonstrated that expressions of FNR1, FNR2, Fd1 and Fd2 were decreased and Fd3 and Fd4 expressions were increased. This suggests that stoichiometry of Fd isoforms might be involved in electron partition to CO2 fixation under elevated CO2 condition. Gene expression profile using rice FNR1 and FNR2 overexpression plants revealed that expression of genes related to nitrogen metabolism were decreased only in FNR2 overexpression plants. This result suggests that electron might be preferentially transferred to nitrogen assimilation pathway in FNR2 overexpression plants whereas linear photosynthetic electron transport is not impaired in FNR1 overexpression plants.
