TL;DR: This work shows that a gene in the Nax2 locus, TmHKT1;5-A, encodes a Na+-selective transporter located on the plasma membrane of root cells surrounding xylem vessels, which is ideally localized to withdraw Na+ from thexylem and reduce transport of Na+ to leaves.

TL;DR: This review considers energy costs of salinity tolerance in crop plants and provides a framework for a quantitative assessment of costs and different sources of energy, and modifications of root system architecture that would maximise water versus ion uptake are addressed.

TL;DR: This review summarizes the current understanding of the components of Na(+) transport in glycophytic plants, including those at the soil to root interface, transport of Na (+) to the xylem, control ofNa(+) loading in the stele and partitioning of the accumulated Na(-) within the shoot and individual cells.

TL;DR: Comparative modeling and evaluation of rice (Oryza sativa) HKT-transporters based on the recent crystal structure of the bacterial TrkH K+ transporter allowed to reconcile transcriptomic and physiological data, and allelic variation of leaf blade Na+ accumulation can be explained by a complex interplay of gene transcription, alternative splicing and protein structure.

TL;DR: It is shown that there is potential to increase the salinity tolerance of bread wheat by manipulation of HKT1;5 genes, a candidate gene underlying the Kna1 locus.
