Summary: This study reveals that the ATS1 gene negatively regulates salt resistance in Arabidopsis. Overexpression of ATS1 leads to decreased salt tolerance in terms of seed germination, biomass, chlorophyll content, pod development, and increased root/shoot ratio and anthocyanidin content. Mutations in the ATS1 gene result in higher levels of unsaturated fatty acids, which stabilize the plasma membrane under salt stress. The ats1 mutants also regulate ion homeostasis by upregulating K+ uptake and downregulating Na+ uptake genes.

Summary: The gene ATL12 plays an important role in the response to salt stress and abscisic acid (ABA) in Arabidopsis thaliana. Overexpression of ATL12 increases the expression of salt stress-associated genes and ABA-responsive genes, and leads to higher levels of reactive oxygen species. Mutants of atl12 are sensitive to salt stress and ABA, and have shorter root length. The findings suggest that ATL12 modulates the response to salt stress and is involved in the ABA signaling pathway.

Summary: A barley vacuolar H+-pyrophosphatase (VP10) plays a critical role in developing salt tolerance by modulating Na+ sequestration into root vacuoles through synergistic action with Na+/H+ antiporters to enhance H+ efflux and K+ maintenance in roots.

Summary: The loss-of-function mutant of the transcription factor NLP7, which regulates the primary response to nitrate, exhibits salt tolerance and a balanced accumulation of nitrate anions and sodium cations. The mutant shows reduced stress response, lower levels of marker genes, and less accumulation of proline, nitric oxide, and reactive oxygen species under high salinity. However, it also accumulates more sodium ions in the shoots and has higher nitrate levels compared to the wild type. These findings suggest that targeting nitrate metabolism and signaling could improve salt tolerance.

Summary: AtALMT12 participates in restricting root-to-shoot Cl- transport and modulates NO3- accumulation in shoots under Cl--salt stress, therefore plays an important role in salt tolerance. Meanwhile, AtALMT12 affects K+ accumulation in shoots under higher KCl condition.

Summary: In this study, a new salt-induced ASR gene (OsASR6) in rice was identified and functionally characterized. Overexpression of OsASR6 enhanced salt and oxidative stress tolerance in rice plants by reducing H2O2, malondialdehyde (MDA), Na/K, and relative electrolyte leakage. Additionally, OsASR6 was found to interact with OsNCED1, a key enzyme in ABA biosynthesis.

Summary: The transcription factor ERF34 plays a crucial role in leaf senescence by modulating the expression of senescence-inducing genes and promoting salt stress tolerance. ERF34 is differentially expressed under various leaf senescence-inducing conditions and negatively regulates leaf senescence induced by age, dark, and salt stress. ERF34 directly binds to and activates the expression of salt stress-responsive genes.

Summary: In this study, 14 putative S-adenosylmethionine decarboxylase genes were identified in upland cotton, and the ectopic expression of one of these genes in Arabidopsis thaliana resulted in enhanced salinity tolerance through increased spermidine accumulation and activation of salinity resistance-related genes.

Summary: Salt stress reduces plant growth and threatens global crop production. The identification of salt tolerance genes from plants inhabiting extreme environments is urgent. HaASR1 overexpression from Haloxylon ammodendron increased salt tolerance in Arabidopsis by enhancing osmotic adjustment, maintaining membrane integrity, improving chlorophyll content, leaf area, and photosynthesis capacity. These results suggest the potential application of HaASR1 in genetic engineering to increase salt tolerance in grass and crop plants.

Summary: AtPHB2 gene was cloned from Arabidopsis thaliana and localized in mitochondria, which was found to promote seed germination and plant growth under different stresses, and enhance resistance to saline-alkali and oxidative stresses. Transgenic plants overexpressing AtPHB2 showed higher K+/Na+ ratio and lower H2O2 content after 24 h of salt treatment, indicating its involvement in reducing reactive oxygen species (ROS) levels and improving plant tolerance to salt stresses.
