Mild proteasomal stress improves photosynthetic performance in Arabidopsis chloroplasts

Most chloroplast proteins are imported from the cytosol and thus transiently exposed to the cytosolic proteasome. Here the authors show that impairment of the cytosolic proteasome can elevate precursor protein abundance and photosynthetic activity suggesting that cytosolic protein turnover is a mean...
