Chloride Improves Nitrate Utilization and NUE in Plants.

ABSTRACT: Chloride (Cl^-) has traditionally been considered harmful to agriculture because of its toxic effects in saline soils and its antagonistic interaction with nitrate (NO₃ ^-), which impairs NO₃ ^- nutrition. It has been largely believed that Cl^- antagonizes NO₃ ^- uptake and accumulation in higher plants, reducing crop yield. However, we have recently uncovered that Cl^- has new beneficial macronutrient, functions that improve plant growth, tissue water balance, plant water relations, photosynthetic performance, and water-use efficiency. The increased plant biomass indicates in turn that Cl^- may also improve nitrogen use efficiency (NUE). Considering that N availability is a bottleneck fo
