Editorial: Enhancing salinity tolerance in crop plants through agronomic, genetic, molecular, and physiological approaches

Soil salinity is expanding by an estimated 1.5 million hectares per year at world level. However, the threat to agricultural productivity, food security and ecosystem conservation is not sensed to be so dramatic as in other sources of environmental concern. Plant tolerance mechanisms, the ways to harness them and the complementary crop management practices constitute the comprehensive domain where responses to this adversity should be sought. Authors of this Research Topic contributed to this quest for solutions. Both large scale crops, namely wheat and maize, and target species as Aegilops tauschii were involved in the attempts to shed light on stress resistance mechanisms, their genetic expressions, and external means to enhance them. Despite a majority of works relying on biotechnological/genetic approaches, no univocal tool/process was address. This makes the results varied, paradigmatic, very stimulating in view of further research and downstream applications.
