PpAOX regulates ER stress tolerance in Physcomitrella patens

Severe environments disturb the folding or assembly of newly synthesized proteins, resulting in accumulation of misfolded or unfolded proteins in the endoplasmic reticulum (ER) as well as cytotoxic aggregation of abnormal proteins. Therefore, ER stress is evoked due to disturbed ER homeostasis. Alternative oxidase (AOX) plays an important role in coping with various abiotic stresses and plant growth. Our previous study has reported that PpAOX is...
