Additive effects of Na+ and Cl– ions on barley growth under salinity stress [PDF]
Journal of Experimental Botany, 2011 Soil salinity affects large areas of the world's cultivated land, causing significant reductions in crop yield. Despite the fact that most plants accumulate both sodium (Na(+)) and chloride (Cl(-)) ions in high concentrations in their shoot tissues when grown in saline soils, most research on salt tolerance in annual plants has focused on the toxic ...

Salinity controls on Na incorporation in Red Sea planktonic foraminifera [PDF]
Paleoceanography, 2016 AbstractWhereas several well‐established proxies are available for reconstructing past temperatures, salinity remains challenging to assess. Reconstructions based on the combination of (in)organic temperature proxies and foraminiferal stable oxygen isotopes result in relatively large uncertainties, which may be reduced by application of a direct ...

Linking salinity stress tolerance with tissue-specific Na+ sequestration in wheat roots [PDF]
Frontiers in Plant Science, 2015 Salinity stress tolerance is a physiologically complex trait that is conferred by the large array of interacting mechanisms. Among these, vacuolar Na+ sequestration has always been considered as one of the key components differentiating between sensitive

Isoosmotic Regulation of Cotton and Peanut at Saline Concentrations of K and Na [PDF]
Plant Physiology, 1988 Peanut (Arachis hypogaea L.) and cotton (Gossypium hirsutum) plants were grown for 4 weeks in saline, isoosmotic rooting substrates with different proportions of K and Na. Isoosmotic media did not affect growth (except at the highest external K concentrations) or estimates of intracellular osmotic pressure in expanding leaves (i.e.

Genetics of Na+ exclusion and salinity tolerance in Afghani durum wheat landraces [PDF]
BMC Plant Biology, 2017 Selecting for low concentration of Na+ in the shoot provides one approach for tackling salinity stress that adversely affects crop production. Novel alleles for Na+ exclusion can be identified and then introduced into elite crop cultivars.We have identified loci associated with lower Na+ concentration in leaves of durum wheat landraces originating from

The Photosynthesis, Na+/K+ Homeostasis and Osmotic Adjustment of Atriplex canescens in Response to Salinity [PDF]
Frontiers in Plant Science, 2016 Atriplex canescens (fourwing saltbush) is a C4 perennial fodder shrub with excellent resistance to salinity. However, the mechanisms underlying the salt tolerance in A. canescens are poorly understood. In this study, 5-weeks-old A. canescens seedlings were treated with various concentrations of external NaCl (0-400 mM).

Lotus tenuis tolerates combined salinity and waterlogging: maintaining O2 transport to roots and expression of an NHX1-like gene contribute to regulation of Na+ transport [PDF]
, 2010 Salinity and waterlogging interact to reduce growth for most crop and pasture species. The combination of these stresses often cause a large increase in the rate of Na+ and Cl− transport to shoots; however, the mechanisms responsible for this are largely

Sodium incorporation in foraminiferal calcite: An evaluation of the Na/Ca salinity proxy and evidence for multiple Na-bearing phases [PDF]
Geochimica et Cosmochimica Acta, 2023 The ratio of sodium to calcium (Na/Ca) in foraminiferal calcite has been proposed as a proxy for salinity, yet relatively little is known about the incorporation of sodium into the shells of foraminifera. Ongoing debates include the location of Na in the calcite crystal lattice, the possibility that at least some Na might be complexed with organics ...

Plant Production Science, 2002 The distributions of Na and chlorophyll in the leaves of rice (Oryza sativa L.) seedlings grown under a saline condition were examined in relation to the anatomical changes caused by salinity. In salt-treated plants, the Na content was higher in older leaves and basal part of the leaf.
