In this opinion article, we challenge the traditional view that breeding for reduced Cl− uptake would benefit plant salinity tolerance. A negative correlation between shoot Cl− concentration and plant biomass does not hold for halophytes – naturally salt tolerant species. We argue that, under physiologically relevant conditions, Cl− uptake requires plants to invest metabolic energy, and that the poor selectivity of Cl−-transporting proteins may explain the reported negative correlation between Cl− accumulation and crop salinity tolerance. We propose a new paradigm: salinity tolerance could be achieved by improving the selectivity of some of the broadly selective...
