“…International Journal of Genomics AtNHX2 in Arabidopsis and AtNHX1 in tomato, rapeseed, and soybean is reported to elicit a salt response and confer tolerance [5,[42][43][44]. Similarly, overexpression of heterologous NHX from Pennisetum glaucum conferred tolerance in tomato [45], and overexpression of NHX from halophyte Suaeda salsa and Arabidopsis respectively increased salt tolerance in transgenic rice and cotton [46].…”

Abiotic stress is the major threat confronted by modern-day agriculture. Salinity is one of the major abiotic stresses that influence geographical distribution, survival, and productivity of various crops across the globe. Plants perceive salt stress cues and communicate specific signals, which lead to the initiation of defence response against it. Stress signalling involves the transporters, which are critical for water transport and ion homeostasis. Various cytoplasmic components like calcium and kinases are critical for any type of signalling within the cell which elicits molecular responses. Stress signalling instils regulatory proteins and transcription factors (TFs), which induce stress-responsive genes. In this review, we discuss the role of ion transporters, protein kinases, and TFs in plants to overcome the salt stress. Understanding stress responses by components collectively will enhance our ability in understanding the underlying mechanism, which could be utilized for crop improvement strategies for achieving food security.

“…Systematic sequencing of the Arabidopsis thaliana genome has identified 35 genes that can encode proteins being similar to antiport Na + /H + . Constitutive overexpression of AtNHX1 improves salinity tolerance also in tomato [124], Brassica napus [125], and soybean [126]. Fukuda et al have identified an AtNHX1 homologue in rice, OsNHX1.…”

Salinity is one of the most serious factors limiting the productivity of agricultural crops, with adverse effects on germination, plant vigor, and crop yield. This salinity may be natural or induced by agricultural activities such as irrigation or the use of certain types of fertilizer. The most detrimental effect of salinity stress is the accumulation of Na+ and Cl− ions in tissues of plants exposed to soils with high NaCl concentrations. The entry of both Na+ and Cl− into the cells causes severe ion imbalance, and excess uptake might cause significant physiological disorder(s). High Na+ concentration inhibits the uptake of K+, which is an element for plant growth and development that results in lower productivity and may even lead to death. The genetic analyses revealed K+ and Na+ transport systems such as SOS1, which belong to the CBL gene family and play a key role in the transport of Na+ from the roots to the aerial parts in the Arabidopsis plant. In this review, we mainly discuss the roles of alkaline cations K+ and Na+, Ion homeostasis-transport determinants, and their regulation. Moreover, we tried to give a synthetic overview of soil salinity, its effects on plants, and tolerance mechanisms to withstand stress.

“…In addition, salinity stress tolerance mechanisms also include a series of ROS scavenging enzyme genes [4], compatible solute synthesis genes [4,19,20] and ion transporters [1,4], which enhance plant adaptations to salinity stress. Some studies have shown that overexpression of the stress-associated genes encoding the ROS scavenging protein TaPRX-2A [21], compatible solute KvP5CS1 [22], ion transporter AtNHX1 [23] and SpSOS1/NHX7 [10] results in enhanced tolerance to salinity stress in transgenic plants, respectively.…”

Background: Pak choi is an important leafy vegetable crop. Salinity is among the most harmful agents that negatively influence pak choi yield. However, the mechanism of salinity tolerance in pak choi has not been well understood. In this study, the root transcriptomics of two cultivars differing in salinity tolerant, Shanghaijimaocai (S, salinity tolerant) and Te’aiqing (T, salinity sensitive), were investigated under 0 and 100 mM NaCl treatments.Results: Using de novo assembly, 214,952 assembled unigenes were generated. Totals of 6765, 2454, 2451 and 5798 differentially expressed unigenes (DEUs) were identified in comparison of S100/S0, T100/T0, S0/T0 and S100/T100, respectively. Shanghaijimaocai is more sensitive to NaCl stress than Te’aiqing in terms of root transcriptomics. Based on GO and KEGG pathway analysis, several osmotic and ionic stress-related genes including MP3K18, PYL8, PP2C15/16/49, ARF2, bHLH112, bZIP43, COL5, CDF1/3, ERF25/60, HSFA6, MYBS3/59/92/CCA1/PHL5, POD21, GOLS7, CIPK4/7/12, NHX7, SLAH1 and ALMT13, showed higher expression in Shanghaijimaocai than in Te’aiqing. These genes, therefore, might be contributed to the difference in salinity tolerance. Moreover, the physiological shift of peroxidase activity was in accordance with dynamic transcript profile of the relevant unigenes. Conclusions: We determined digital expression profile and discovered a broad survey of unigenes associated with the difference of salinity tolerance between Shanghaijimaocai and Te’aiqing. These findings would be useful for further functional analysis as potential targets to improve resistance to salinity stress via genetic engineering.
