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:

Phytoremediation of Salt-Impacted Soils and Use of Plant Growth-Promoting Rhizobacteria (PGPR) to Enhance Phytoremediation
Karen E. Gerhardt,Gregory J. MacNeill,Gregory J. MacNeill,Perry D. Gerwing,Bruce M. Greenberg +4 more
TL;DR: Using plant growth-promoting rhizobacteria (PGPR) in PGPR-Enhanced Phytoremediation Systems (PEPS), positive effects of PGPR on plant biomass and health have been observed in greenhouse and field experiments as discussed by the authors.

Overexpression of PeHKT1;1 Improves Salt Tolerance in Populus.
TL;DR: In further characterization of its functions, overexpression of PeHKT1;1 in Populus davidiana × Populus bolleana resulted in a better relative growth rate in phenotypic analysis, and exhibited higher catalase, peroxidase (POD), and superoxide dismutase (SOD) activities than non-transgenic poplar under salt stress conditions.

Foliar applied fullerol differentially improves salt tolerance in wheat through ion compartmentalization, osmotic adjustments and regulation of enzymatic antioxidants.
TL;DR: Overall, 40 and 80 nM fullerol spray improved photosynthetic activity, osmolytes accumulation and altered tissue ion compartmentalization which contributed to improvement in grain yield attributes under salinity.

Overexpression of Arabidopsis AnnAt8 Alleviates Abiotic Stress in Transgenic Arabidopsis and Tobacco
TL;DR: A role is suggested for AnnAt8 in enhancing abiotic stress tolerance at different stages of plant growth and development and the enhanced tolerance exhibited by the transgenic plants can be correlated with altered expressions of these stress-regulated genes.

He-Ne laser preillumination improves the resistance of tall fescue (Festuca arundinacea Schreb.) seedlings to high saline conditions.
Limei Gao,Yongfeng Li,Rong Han +2 more
TL;DR: The data illustrated that He-Ne laser preillumination contributed to conferring an increased tolerance to salt stress in tall fescue seedlings due to alleviating oxidative damage through scavenging free radicals and inducing transcriptional activities of some genes involved in plant antioxidant system, and the induction of phytochromeB transcriptional level by He- Ne laser was probably correlated with these processes.

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.
Journal ArticleDOI
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.
