Abstract excerpt

Chlorophagy is an autophagy pathway that delivers chloroplast components into the vacuole for degradation, thus eliminating damaged chloroplasts. Chloroplast degradation is observed in Arabidopsis (Arabidopsis thaliana) mutants of MALTOSE-EXCESS 1 (MEX1), a maltose exporter in the chloroplast inner envelope membrane. However, whether autophagy is involved in the mex1 phenotypes is unknown. To extend our...
