Learning from halophytes: physiological basis and strategies to improve abiotic stress tolerance in crops.
TLDR
In this article, a major breakthrough in crop breeding for salinity tolerance was proposed, where stress tolerance genes and mechanisms were identified in extremophiles and then introduced into traditional crops, given the limited range of genetic diversity in this trait within traditional crops.About:

Salinity tolerance of crops – what is the cost?
TL;DR: In this article, the authors consider mechanisms of adaptation and highlight recent research examples through a lens of their applicability to improving the energy efficiency of crops under saline field conditions, and highlight some recent examples.

Shah Fahad,Saddam Hussain,Amar Matloob,Faheem Ahmed Khan,Abdul Khaliq,Shah Saud,Shah Hassan,Darakh Shan,Fahad Khan,Najeeb Ullah,Muhammad Faiq,Muhammad Rafiullah Khan,Afrasiab Khan Tareen,Aziz Khan,Abid Ullah,Nasr Ullah,Jianliang Huang +16 more
TL;DR: Current progress is exemplified by the identification and validation of several significant genes that enhanced crops tolerance to salinity, while missing links on different aspects of phytohormone related salinity tolerance are pointed out.

The Role of Na+ and K+ Transporters in Salt Stress Adaptation in Glycophytes.
TL;DR: It turns out that these transporters and channels are equally important for the adaptation of glycophytes as they are for halophytes, but differential gene expression, structural differences in the proteins and post-translational modifications account for the differences in tolerance between the two groups.
Journal ArticleDOI
Regulation of potassium transport in plants under hostile conditions: implications for abiotic and biotic stress tolerance.
TL;DR: It is argued that cytosolic K(+) content may be considered as one of the 'master switches' enabling plant transition from the normal metabolism to 'hibernated state' during first hours after the stress exposure and then to a recovery phase.

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.

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.
Journal ArticleDOI
Comparative physiology of salt and water stress
TL;DR: It is important to avoid treatments that induce cell plasmolysis, and to design experiments that distinguish between tolerance of salt and tolerance of water stress, to understand the processes that give rise toolerance of salt, as distinct from tolerance of osmotic stress.
Journal ArticleDOI
Salinity tolerance in halophytes
TL;DR: Halophytes, plants that survive to reproduce in environments where the salt concentration is around 200 mm NaCl or more, constitute about 1% of the world's flora and research should be concentrated on a number of 'model' species that are representative of the various mechanisms that might be involved in tolerance.
Journal ArticleDOI
Improving crop salt tolerance
TL;DR: Evaluation of claims in the literature that the transfer of a single or a few genes can increase the tolerance of plants to saline conditions reveals that, of the 68 papers produced between 1993 and early 2003, only 19 report quantitative estimates of plant growth.
