Plant Responses and Tolerance to Salinity Stress, 2nd Edition

Dear Colleagues,

Due to climate change, the overexploitation of aquifers, and the use of reclaimed water for agriculture, salinity is becoming one of the most significant environmental factors that most limit crop yield. To solve this problem, several strategies have been explored. Such strategies range from the remediation of soils to the discovery of crops (cultivars) that are more tolerant to salinity stress. Salinity has an osmotic and toxic effect on plants. Osmotic effects induce a physiological drought on plants due to the retention of more water in soil, and this causes similar plant responses to those under water-limited conditions. Toxic effects are produced by an excess of sodium ions in the soil solution, which can displace potassium and other ions and cause an imbalance in the K+/Na+ ratio. This can also cause an imbalance of other essential ions and can therefore lead to membrane and protein damage and, in some extreme cases, plant death. For this Topic, we seek manuscripts that address plant response and tolerance mechanisms to cope with salinity stress and management actions to mitigate it. We encourage the submission of papers that feature experiments conducted in field, greenhouse or growth chambers and adopt various approaches, from assessing agronomic traits to investigating molecular mechanisms. Moreover, manuscripts with a physiological and biochemical focus and those that use multi-omics approaches are also welcome.
