TLDR
There is greater understanding about how cellular transport systems functionally integrate to facilitate tissue and organismal Na + homeostasis, and notable in this process are HKT1 Na + transporters, which regulate Na + loading into the root xylem, limiting flux to and accumulation in the shoot.About:

A laser ablation technique maps differences in elemental composition in roots of two barley cultivars subjected to salinity stress
TL;DR: The results show that LA-ICP-MS can be used for fine mapping of soluble ions (ie. Na+ and K+ ) in plant tissues, providing insight into the link between Na+ toxicity and root growth responses to salt stress.
Journal ArticleDOI
Shoot chloride translocation as a determinant for NaCl tolerance in Vicia faba L.
TL;DR: The concentration of Cl- at the time point of developing leaf necrosis was in the same range irrespective of the variety, while that of Na+ varied, indicating that Cl- concentrations, and not Na+ concentrations are critical for the formation of salt necrosis in faba bean.

Salt Tolerance and Potential Uses for Saline Agriculture of Halophytes from the Poaceae
Abdallah Atia,Ahmed Debez,Mokded Rabhi,Zouhaier Barhoumi,Chiraz Chaffei Haouari,Houda Gouia,Chedly Abdelly,Abderrazak Smaoui +7 more
TL;DR: Using halophytes from the Poaceae family to establish productive ecosystems and re-greening natural saline soils could be a useful approach to valorize and reclaim salt-affected areas and overcome water shortage issue.

PGPR assisted bioremediation of heavy metals and nutrient accumulation in Zea mays under saline sodic soil
TL;DR: In this paper, the effects of four plant growth promoting rhizobacteria; Pseudomonas putida, Bacillus pumilus, Lysinibacillus sphaericus and Exiguobacterium aurantiacum isolated from saline soil on the uptake, accumulation and translocation of essential nutrients and heavy metals in Zea mays L. grown in a saline sodic field.

Mechanisms of salinity tolerance
Rana Munns,Mark Tester +1 more
TL;DR: The physiological and molecular mechanisms of tolerance to osmotic and ionic components of salinity stress are reviewed at the cellular, organ, and whole-plant level and the role of the HKT gene family in Na(+) exclusion from leaves is increasing.

REACTIVE OXYGEN SPECIES: Metabolism, Oxidative Stress, and Signal Transduction
Klaus Apel,Heribert Hirt +1 more
TL;DR: The mechanisms of ROS generation and removal in plants during development and under biotic and abiotic stress conditions are described and the possible functions and mechanisms for ROS sensing and signaling in plants are compared with those in animals and yeast.
Journal ArticleDOI
Oxidative stress, antioxidants and stress tolerance
TL;DR: Key steps of the signal transduction pathway that senses ROIs in plants have been identified and raise several intriguing questions about the relationships between ROI signaling, ROI stress and the production and scavenging ofROIs in the different cellular compartments.

Salt and drought stress signal transduction in plants
TL;DR: Salt and drought stress signal transduction consists of ionic and osmotic homeostasis signaling pathways, detoxification (i.e., damage control and repair) response pathways, and pathways for growth regulation.
Journal ArticleDOI
Plant cellular and molecular responses to high salinity.
TL;DR: Evidence for plant stress signaling systems is summarized, some of which have components analogous to those that regulate osmotic stress responses of yeast, some that presumably function in intercellular coordination or regulation of effector genes in a cell-/tissue-specific context required for tolerance of plants.
