“…Thus, plants have issue with several efficient mechanisms enabling them to survive under those potentially adverse environmental conditions (Roux et al 2014;Mickelbart et al 2015). In this regard, there are several reports documenting negative and positive interactions in conditions of combined abiotic stresses such as salinity-drought, potassium deficiency-heavy metals (Liu et al 2013), salinity-phosphorus deficiency (Singh and Blanke 2000;Akhtari et al 2019;Talbi Zribi et al 2017, 2020, salinity-K + deficiency (Hafsi et al 2010(Hafsi et al , 2017Nieves-Cordones et al 2019b), drought-heat (Cohen et al 2021), and salt-osmotic-heat (Sewelam et al 2020) stresses. But various abiotic (heat and drought) combined with biotic (virus) stresses have been reported (Prasch and Sonnewald 2013).…”

Salinity is one of the most constraining environmental factors that limits plant growth and productivity because it disturbs mineral nutrition by triggering interactions at the interface soil roots. It implies a notable competition between sodium (Na+) and potassium (K+), with this last mineral being a key nutrient for plants. Using the halophyte Cakile maritima as a model plant grown in hydroponic conditions, this study was aimed to analyze how the simultaneous stressful conditions of high salinity (400 mM NaCl) and K+ deficiency (0 mM) for 15 days affect plant growth, ion balance, and antioxidant and NADPH-generating systems. Among the parameters analyzed, the most remarkable changes were observed in leaves, with drastic increases in the Na+/K+, Na+/Ca2+ and Na+/Mg2+ ratios, an enhanced accumulation of anthocyanins, and the induction of 3 new copper/zinc superoxide dismutase (CuZnSOD) isozymes in plants simultaneously exposed to both stresses. Taken together, the data revealed that the combination of both, high salinity and K+ deficiency, caused oxidative stress and modulated the whole antioxidative response of C. maritima in leaves and roots. Besides the differential response underwent by both organs, considering the different parameters analyzed under these stressful conditions, the most notable traits were that the effect of both stresses seems to be not additive and that salinity appears to improve C. maritima response to K+, a behavior not manifested in glycophyte species. Taken together our data support that, under extreme conditions that lead to an excess of ROS production, the induction of several CuZn-SODs in C. maritima may be one of the most outstanding strategies for the adaptation of this plant species to survive.

“…It can also be caused by human‐induced practices such as irrigation. In arid and semi‐arid regions, soil salinity and sodicity are the most important limiting factors for crop production (Akhtari et al, 2019). In such areas, the prime cause of secondary soil salinity is irrigation water quality and/or quantity (Asadi Kapourchal et al, 2013).…”

“…Salinity and phosphorus (P) deficiency are two worldwide environmental constraints that significantly contribute to reduce plant growth and productivity (Akhtari et al 2019). Phosphorus (P) is a critical macronutrient required for numerous physiological and biochemical functions in plants including energy transfer, signal transduction, biosynthesis of macromolecules, photosynthesis, and respiration (Raghothama and Karthikeyan 2005).…”

Halophytes are plants which are naturally found in saline habitats where generally a number of abiotic stresses such as salinity and phosphorus (P) deficiency coexist. Although the individual effects of salinity and P shortage have been largely studied and are well described in the literature, information about the physiological behavior of halophytes to the combined effects of salinity and P deficiency is rare. Moreover, there is no cut mechanistic explanation about the relationships between these two stresses. However, halophytes are often subjected to the combined effects of these two stresses principally in calcareous saltaffected soils characterized by high pH and low P solubility. Cross-tolerance is the mechanism by which a plant resistance to a stress incites resistance to another. Many studies pointed out that osmotic adjustment, nutrient homeostasis, oxidative stress tolerance, and enhanced biosynthesis of
