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:

Mechanism of Salinity Tolerance in Plants: Physiological, Biochemical, and Molecular Characterization
Bhaskar Gupta,Bingru Huang +1 more
TL;DR: This paper provides a comprehensive review of major research advances on biochemical, physiological, and molecular mechanisms regulating plant adaptation and tolerance to salinity stress.
Journal ArticleDOI
Genetic mechanisms of abiotic stress tolerance that translate to crop yield stability.
TL;DR: An effective new paradigm is the targeted identification of specific genetic determinants of stress adaptation that have evolved in nature and their precise introgression into elite varieties.
Journal ArticleDOI
Sodium chloride toxicity and the cellular basis of salt tolerance in halophytes
TL;DR: In this article, the authors discuss the evidence for Na+ and Cl− toxicity and the concept of tissue tolerance in relation to halophytes and suggest that halophyte tolerate cytoplasmic Na+/Cl− concentrations of 100-200mm.
Journal ArticleDOI
Regulation of Na+ and K+ homeostasis in plants: towards improved salt stress tolerance in crop plants
TL;DR: This review will introduce salt stress responses in plants and summarize the current knowledge about the most important ion transporters that facilitate intra- and intercellular K+ and Na+ homeostasis in these organisms.

Microsatellite signature of ecological selection for salt tolerance in a wild sunflower hybrid species, Helianthus paradoxus
TL;DR: In this paper, the authors identified three genomic regions -Survivorship quantitative trait loci (QTLs) - that were under strong selection in experimental hybrids transplanted into the natural habitat of H. paradoxus.

MIZ1, an essential protein for root hydrotropism, is associated with the cytoplasmic face of the endoplasmic reticulum membrane in Arabidopsis root cells
Tomokazu Yamazaki,Yutaka Miyazawa,Akie Kobayashi,Teppei Moriwaki,Nobuharu Fujii,Hideyuki Takahashi +5 more
TL;DR: The signal corresponding to MIZ1‐GFP was detected at high levels in cortical cells and lateral root cap cells and accumulated in compartments in cortical Cells.

Differential expression of candidate salt-tolerance genes in the halophyte Helianthus paradoxus and its glycophyte progenitors H. annuus and H. petiolaris (Asteraceae).
Cécile Edelist,Xavier Raffoux,Matthieu Falque,Christine Dillmann,Delphine Sicard,Loren H. Rieseberg,Sophie Karrenberg +6 more
TL;DR: Semiquantitative RT-PCR was used to study the expression of eight candidate salt-tolerance genes in leaves of the highly Salt-tolerant diploid hybrid species Helianthus paradoxus and its salt-sensitive progenitor species H. annuus and H. petiolaris, suggesting that these genes are involved in sustained growth under saline conditions inHelianthus.

TL;DR: Heightened expression of AVP1 enhances pyrophosphate-dependent proton pump activity, salt tolerance, ion vacuolar sequestration, K⁺ uptake capacity, root hair development, osmotic responses, and PM ATPase hydrolytic and proton pumping activities.

Water-deficit tolerance in citrus is mediated by the down regulation of PIP gene expression in the roots
Juan Rodríguez-Gamir,Gema Ancillo,Frederic Aparicio,Mireia Bordas,Eduardo Primo-Millo,M. Ángeles Forner-Giner +5 more
TL;DR: Low aquaporin levels, or down-regulated Aquaporin expression, accompanied by decreased plant vigour led to decreased plasma membrane permeability, thereby facilitating water retention in the cells under water stress conditions, which may induce water stress tolerance in citrus rootstocks.
