Summary: This study analyzed the function of Na+/K+-ATPase in the response of Neoporphyra haitanensis to salt stress and found that it played a crucial role in maintaining the K+/Na+ homeostasis in the algae. The inhibitor ouabain caused Na+ accumulation and K+ leakage in the cells, disrupting the K+/Na+ balance and leading to decreased photosynthesis and oxidative damage in the algae.

Summary: Soil salinization affects crop growth by inducing osmotic stress and ion toxicity. NHX gene family plays a crucial role in plant response to salt stress through regulating sodium ion transport. This study identified and characterized 26 NHX genes in three cultivars of Cucurbita L., and found that genes in the same subfamily may have similar functions while genes in other subfamilies may have functional diversity. Additionally, it was discovered that some NHX genes have key cis-acting elements associated with salt stress response.

Summary: A novel NHX gene named CsNHX6 was cloned from tea plant, and its overexpression enhanced the salt tolerance of yeast and Arabidopsis by increasing the Na+ storage capacity of cells. CsNHX6 was localized in various organelles including Golgi, TGN, PVC and vacuole, and this localization was enhanced by salt stress.

Summary: Plant metabolites are dynamically modified and distributed in response to environmental changes. Maintaining ion homeostasis under salt stress requires coordinated activation of two types of central regulators: plasma membrane (PM) H+-ATPase and Na+/H+ antiporter. In this study, we identified phosphatidylinositol (PI) and phosphatidylinositol 4-phosphate (PI4P) as key molecules in regulating ion homeostasis under salt stress in Arabidopsis.

Summary: Salinity affects the growth and photosynthesis of Avicennia marina, a mangrove plant. At 200 mM NaCl, the whole-plant dry weight and photosynthetic parameters increased, but decreased over 400 mM NaCl. High salinity caused reduction in starch grain size, swelling of thylakoids, separation of granal stacks, and even destruction of the envelope. The salt glands in the adaxial epidermis of the leaves excrete Na+ effectively below 400 mM NaCl, improving its salt tolerance.

Summary: In this study, the researchers identified seven SlNHX genes in the tomato genome and investigated their expression patterns in the open flower tissues under salt shock. They found that SlNHX6 and SlNHX8 are associated with the stress-related MeJA hormone and physically interact with Salt Overly Sensitive (SOS) pathway proteins, respectively. The transcriptome analysis showed that the SlNHX2 and SlNHX6 genes were highly expressed in the open flower tissues and all SlNHX genes, especially SlNHX6 and SlNHX8, were significantly upregulated by salt shock. These findings provide valuable insights for future genetic research and breeding strategies against salt stress in tomatoes.

Summary: This study investigated the factors affecting selenite uptake in Rahnella aquatilis HX2 and found that selenite uptake was concentration- and time-dependent, and pH-dependent. The water channel protein AqpZ, sulfite, and the Na+/H+ antiporter NhaA were identified as important regulators of selenite uptake.

Summary: In this study, two Na+/H+ antiporter genes, nhaC1 and nhaC2, were identified from Natronorubrum daqingense. These genes were able to confer tolerance to high salt concentrations and alkaline pH to salt-sensitive Escherichia coli KNabc. Functional analysis showed that both NhaC1 and NhaC2 exhibited Na+(K+, Li+)/H+ antiport activities, which were pH-dependent and optimal at pH 9.5. Phylogenetic analysis revealed that NhaC1 and NhaC2 belong to the Na+/H+ antiporter NhaC family and are distinct from Bacillus NhaC proteins.

Summary: Potassium (K) application can alleviate cotton salt stress and improve fiber length and the maximum velocity of fiber elongation. It also increases enzyme activities and osmolyte contents. The effect of K application on fiber elongation decreases with increasing salt stress, with CCRI-79 responding to K application better than Simian 3.
