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:

Quantitative Visualization of Molecular Delivery and Uptake at Living Cells with Self-Referencing Scanning Ion Conductance Microscopy-Scanning Electrochemical Microscopy.
TL;DR: A multifunctional dual-channel scanning probe nanopipet that enables simultaneous scanning ion conductance microscopy and scanning electrochemical microscopy measurements is demonstrated to have powerful new capabilities for spatially mapping the uptake of molecules of interest at living cells.

The wheat NHX antiporter gene TaNHX2 confers salt tolerance in transgenic alfalfa by increasing the retention capacity of intracellular potassium
TL;DR: The transgenic alfalfa plants had lower K+ efflux through specific K+ channels and higher K+ absorption through high-affinity K+ transporters than did the wild-type plants and had greater K+ contents and [K+]/[Na+] ratios in leaf tissue and cell sap.

TL;DR: RNA-seq results, along with the phenotype and physiological results, suggested that the salt-tolerant maize inbred line TL1317 possesses more rapidly and effectively responses to remove toxic Na+ ions and maintain K+ under salt stress than the Salt-sensitive maize inbreeding line SL1303.

A Cation-Chloride Cotransporter Gene Is Required for Cell Elongation and Osmoregulation in Rice
TL;DR: Results suggest that OsCCC1 is involved in the cell elongation by regulating ion (Cl−, K+, and Na+) homeostasis to maintain cellular osmotic potential.

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.
