The paper shows that under high light stress in Arabidopsis, nuclear-encoded enzymes with increased degradation rates are compensated by transcriptional upregulation to maintain proteostasis, while plastid-encoded proteins rely on other mechanisms.

The paper identifies autophagic protein cargo in Arabidopsis by analyzing changes in protein abundance and degradation rates in autophagy mutants.

This study shows autophagy promotes photomorphogenesis in Arabidopsis seedlings under carbon limitation by enhancing lipid turnover and chloroplast development.
