Nitrate (NO 3 − ) not only serves as an essential nutrient to ensure plant growth and development and is involved in protein and nucleic acid synthesis, NO 3 − stored in vacuoles can also reduce osmotic potential to help plants absorb water under changeable stress conditions. Moreover, effective remobilization of stored NO 3 − is important to maintain plant development in nature. In this paper, we review the literature on the role of NO 3 − stored vacuoles in osmotic regulation and NO 3 − remobilization under stress conditions, particularly for halophytes under salinity stress. Knowledge of how halophytes deal with adverse effects by using NO 3 − as an osmolyte will be helpful for making better decisions to improve abiotic stress resistance in plant production.
