Outline of Final Research Achievements |
We aimed to reveal roles of autophagy in the life cycle of rice and obtained following results. (1) We isolated autophagy-defective rice mutants. (2) We established monitoring methods for autophagy by generating transgenic rice expressing fluorescent protein markers. (3) We found that autophagy-defective rice mutants show delayed reproductive growth and heading and they show male sterile phenotype due to incomplete development of pollen and anther. (4) We found that autophagy-defective rice mutants show reduced biomass production and nitrogen use efficiency due to suppression of chloroplast protein degradation and nitrogen remobilisation.
