Physiological and Molecular Responses to Salinity Due to Excessive Na+ in Plants
2021Salinity due to excessive sodium ions in plants is amongst one such abiotic stresses that are severely hampering crop productivity. Most plants are severely affected by excess sodium ions in soil. This abiotic stress creates relatively more problems in plants belonging to glycophytes group than the ones to halophytes group by interrupting their ...

Contribution of two different Na+ transport systems to acquired salinity tolerance in rice
Plant Science, 2020To elucidate the mechanisms of salt acclimation, physiological parameters of 70 rice varieties were compared under control and salt stress conditions after the acclimation treatment. The results indicated that some rice varieties had the ability to acclimatize to salt stress, exhibiting improved growth following the acclimation treatment under ...

Renal Na‐K‐ATPase Activity during Saline Infusion in the Rabbit
Acta Physiologica Scandinavica, 1977AbstractDuring saline infusion, sodium reabsorption (RNa) in the diluting segment (thick ascending limb of Henle's loop) increases acutely. The mechanism for this higher pumping rate of outer medullary Na‐K‐ATPase is unknown. Following left‐sided nephrectomy, immediate i.v.

Reassessment of tissue Na+ concentration as a criterion for salinity tolerance in bread wheat
Plant, Cell & Environment, 2007ABSTRACTWheat is the most important crop grown on many of world's saline and sodic soils, and breeding for improved salinity tolerance (ST) is the only feasible way of improving yield and yield stability under these conditions. There are a number of possible mechanisms by which cereals can tolerate high levels of salinity, but these can be considered ...

Characterization of Na+ exclusion mechanism in rice under saline-alkaline stress conditions
Plant Science, 2019This study was designed to elucidate the physiological responses of two rice genotypes to different pH levels under high saline stress. A salt-tolerant cultivar, FL478, and a salt-sensitive cultivar, IR29, were exposed to saline-alkaline solutions supplemented with 50 mM Na at pH 9 (severe), pH 8 (moderate), and pH 7 (mild) for three weeks. The results

Wheat grain yield on saline soils is improved by an ancestral Na+ transporter gene
Nature Biotechnology, 2012The ability of wheat to maintain a low sodium concentration ([Na(+)]) in leaves correlates with improved growth under saline conditions. This trait, termed Na(+) exclusion, contributes to the greater salt tolerance of bread wheat relative to durum wheat.

A Thermodynamic Analysis on the Effect of Salinity on Interlayer Space of Na-Montmorillonite
MRS Advances, 2016Bentonite is used as one of the materials for engineered barrier systems in a radioactive waste repository. Since the major clay mineral constituent of bentonite is montmorillonite, its physico-chemical properties are important. Basal spacing of water-saturated Na-montmorillonite is reported to decrease with increasing Na-montmorillonite density.

Age-related changes in Na+ excretion in saline-loaded spontaneously hypertensive rats
American Journal of Physiology-Legacy Content, 1976The ability of 6- to 7-, 12- to 13-, and 16- to 17-wk-old spontaneously hypertensive rats (SHR) to excrete an acutely administered, isotonic saline load (equivalent to 4.5% body wt) was evaluated. Female SHR from two different colonies were studied. Age-matched female Wistar (W) and Wistar-Kyoto (WKY) rats served as controls. At age 6 wk, the fraction

In order to develop shrimp farming with the percolating water from coastal saline-alkali soil, the effects of the salinity and Na+/K+ in this percolating water on the survival, growth, metabolism, and glutamic oxaloacetic transaminase (GOT), glutamicpyruvic transaminase (GPT) and Na+-K+-ATPase activities of Litopenaeus vannamei were investigated.

Changes in the intracellular concentrations of Na+ and K+ of fetal human fibroblasts have been followed after replacement of serum-containing growth media with unsupplemented and serum-supplemented saline solution (Earle's balanced salt solution). Incubation in unsupplemented salt solution was followed by a progressive increase of the internal Na ...
