| Outline of Final Research Achievements |
The purpose of this research was isolation and study of gene(s), which prolongs the heading time of rice under high nitrogen (N) content. By a genome wide association study (GWAS), we identified HD6 which delays the heading time through the collaborations of HD1 and HD2. The mRNA of HD6 was not changed by the N level but its protein was increased by its increased stability, and the increased HD6 enhanced the HD2 protein level. HD2 suppresses the induction activity of HD1 to HD3a (florigen) expression, whereas HD6 is involved in this regulation through regulating the HD2 by dose-dependent manner.
