| Outline of Final Research Achievements |
In rice, a promoter of Rubisco small subunit gene, OsRBCS3, was activated by transcription factors OsDREB1E and OsDREB1G. Two DRE factors which existed in the OsRBCS3 promoter were necessary for this activation. In addition, OsDREB1E and OsDREB1G interacted with the DRE factors in the OsRBCS3 promoter directly. Furthermore, the expression of OsDREB1E and the OsDREB1G genes was induced in response to nitrogen supply. These results suggest that OsDREB1E and OsDREB1G regulate the transcription of the OsRBCS3 gene in response to nitrogen levels.
