“…In soybean, GmPKS4 improves soybean tolerance to salt and salt-alkali stresses. The overexpression of GmPKS4 enhances the scavenging of ROS, osmolyte synthesis, and transcriptional regulation of stress-related genes (Ketehouli et al, 2021). In Brachypodium distachyon, BdCIPK31 positively regulates salt stress in stomatal closure, ion homeostasis, ROS scavenging, osmolyte biosynthesis, and transcriptional regulation of stress-related genes (Luo Q. et al, 2017).…”

As two coexisting abiotic stresses, salt stress and alkali stress have severely restricted the development of global agriculture. Clarifying the plant resistance mechanism and determining how to improve plant tolerance to salt stress and alkali stress have been popular research topics. At present, most related studies have focused mainly on salt stress, and salt-alkali mixed stress studies are relatively scarce. However, in nature, high concentrations of salt and high pH often occur simultaneously, and their synergistic effects can be more harmful to plant growth and development than the effects of either stress alone. Therefore, it is of great practical importance for the sustainable development of agriculture to study plant resistance mechanisms under saline-alkali mixed stress, screen new saline-alkali stress tolerance genes, and explore new plant salt-alkali tolerance strategies. Herein, we summarized how plants actively respond to saline-alkali stress through morphological adaptation, physiological adaptation and molecular regulation.

“…However, as the constitutive level of SOS1 remains unchanged in rice under NaCl stress (Gupta & Shaw 2021), Ca 2+ signalling for expression of OsCIPK (SOS2), as found in the present study, becomes of paramount importance in salt tolerance as a regulator determining movement of Na + . Recently Ketehouli et al (2021) showed that hairy root transformation of soybean overexpressing GmPKS4 (GmCIPK6) confers plant salt tolerance.…”

“…The major bottleneck in transfer of salt tolerance characteristics to salt‐sensitive crop plants is the quantitative nature of the trait, being controlled and facilitated by several gene products, which either function as effectors or regulators (Munns & Testers 2008; Gupta & Shaw 2021; Ketehouli et al . 2021). A low rate of Na + uptake by roots and its transport to shoots, together with maintenance of high selectivity for K + over Na + is considered a primary feature of salt tolerance (Tester & Davenport 2003), although cellular compartmentation of Na + and osmotic adjustment are also significant (Munns & Tester 2008).…”

The protective effect of Ca 2+ against NaCl toxicity was investigated in two rice varieties with contrasting for salt tolerance to understand the mechanistic details of the antagonism to address adverse effects of salinity on agriculture.• The study primarily examined the influence of Ca 2+ on expression/activity of the effectors and regulators involved in Na + translocation.• Calcium reduced uptake of Na + concomitant with higher tissue K + /Na + in seedlings, comparatively more in salt-tolerant Nona Bokra than in salt-sensitive IR-64, together with a significant increase in root PM H + ATPase in the former, but not in the latter. Increased antagonism in Nona Bokra could be the result of Ca 2+ signalling-mediated phosphorylation of PM H + ATPase in roots caused by a significant Ca 2+ -dependent increase in expression of OsCIPK24, which did not occur in IR-64. Furthermore, significant Ca 2+ -mediated NaCl-induced increase in transcription of 14-3-3 protein in Nona Bokra, but not in IR-64, might also lead to a greater protective effect of Ca 2+ in the former, as 14-3-3 protein is essential for activating PM H + ATPase.• Thus, efficient functioning of PM H + ATPase could be key in determining resistance of plants to salinity, implying that identification of the Ca 2+ -dependent kinase phosphorylating the PM H + ATPase threonine residue and manipulation of its expression, together with expression of 14-3-3 proteins could be an important strategy to improve salt tolerance of crops and their cultivation in salt-affected lands.
