| Outline of Final Research Achievements |
The expression profiling of nitrogen and phosphorus nutrient indicator genes throughout the growth of rice plant revealed synchronous changes of nitrogen and phosphorus nutrient status observed at about 30 days after transplanting, expression of phosphorus acquisition system under soil conditions with high phosphate retention capacity, and differences in nutrient status dynamics among cultivars. Furthermore, it was suggested that various metabolic pathways and transcriptional factors would be associated with the nutrient status changes through the analysis of mutants, phenotypes of which emerged at the timing of the nutrient status changes.
