| Outline of Final Research Achievements |
Autophagy is the major system responsible for the degradation of organelles and cytosolic macromolecules in the vacuole. So far, I have found that autophagy defective mutants (atg mutants) show dark-induced senescence phenotype. However, the reason why defect of autophagy accelerates the senescence phenotype remains to be elucidated.
In this research, I screened suppressors which do not show the accelerated dark-induced senescence phenotype, and isolated 6 independent suppressors. Then, by whole genome sequencings, I identified the putative responsible genes for the suppressors. I also tried to elucidate the physiological functions of plant autophagy under the darkness and further establish research bases for elucidation of molecular mechanisms of dark-induced senescence processes.
