This review begins by summarizing the research in Arabidopsis with a focus on the findings of three membrane transporters that are important for salt tolerance: SOS1, AtHKT1, and AtNHX1, then reviews the recent studies in salt tolerance in crops and halophytes.
Mechanisms of sodium uptake by roots of higher plants

The negative impact of soil salinity on agricultural yields is significant. For agricultural plants, sensitivity to salinity is commonly (but not exclusively) due to the abundance of Na+ in the soil…

The findings suggest that, under arid environments, Z. xanthoxylum is able to accumulate a high concentration of Na(+) in its leaves and use it directly for osmotic adjustment, which was coupled with an improvement in leaf hydration and photosynthetic activity.
Puccinellia tenuiflora maintains a low Na+ level under salinity by limiting unidirectional Na+ influx resulting in a high selectivity for K+ over Na+.

Puccinellia tenuiflora has stronger selectivity for K+ over Na+ allowing it to maintain significantly lower tissue Na+ and higher K+ concentration than that of wheat under short- or long-term NaCl treatments, showing that it is a useful monocotyledonous halophyte that might be used for improving salt tolerance of cereals.
Low-Affinity Na+ Uptake in the Halophyte Suaeda maritima1[C][W][OA]

- 31 August 2007
The data suggest that neither nonselective cation channels nor a low-affinity cation transporter are major pathways for Na+ entry into root cells, and it is proposed that two distinct low-Affinity Na+ uptake pathways exist in S. maritima.
Induced growth promotion and higher salt tolerance in the halophyte grass Puccinellia tenuiflora by beneficial rhizobacteria

This study provides the physiological and molecular evidence that application of selected bacteria to salt-tolerant Monocots can ameliorate deleterious effects of high soil saline toxicity.
Augmenting Sulfur Metabolism and Herbivore Defense in Arabidopsis by Bacterial Volatile Signaling

- 8 April 2016
A previously unidentified mechanism by which the growth-promoting rhizobacterium Bacillus amyloliquefaciens (GB03) transcriptionally activates genes responsible for sulfur assimilation, increasing sulfur uptake and accumulation in Arabidopsis is reported.
ZxSOS1 is essential for long-distance transport and spatial distribution of Na+ and K+ in the xerophyte Zygophyllum xanthoxylum

Background and aimsTwo major adaptive strategies used by Zygophyllum xanthoxylum, a C3 succulent xerophyte, against arid environments are absorbing a great quantity of Na+ from low-salinity soil…
Ultrastructural and physiological responses of potato (Solanum tuberosum L.) plantlets to gradient saline stress
- Huijuan Gao, Hong-Yu Yang, Y. Chen
- Biology, MedicineFrontiers in Plant Science
- 13 January 2015
The results indicated that potato plantlets adapt to salt stress to some extent through accumulating osmoprotectants, such as proline, increasing the activities of antioxidant enzymes,such as CAT and SOD.
