| Research Abstract |
Autophagy is the major system responsible for the degradation of organelles and cytosolic macromolecules in the vacuole. I found that dysfunctional peroxisomes were highly accumulated in leaves of autophagy-defective mutants, indicating that autophagy is involved in quality control of leaf peroxisomes in plants. I also tried to elucidate molecular mechanisms for selective peroxisome degradation in Arabidopsis.
