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 and tolerant species and genotypes. However, vacuolar Na(+) sequestration has been rarely considered in the context of the tissue-specific e...

Physiol Genomics 46: 123–137, 2014. First published December 24, 2013; doi:10.1152/physiolgenomics.00105.2013.—Osmoregulatory capabilities have played an important role in the evolution, dispersal, and...

Groundnut is an important oilseed, food and feed crop of our country whose productivity is curtailed due to biotic and abiotic stresses. Salinity is one of the important abiotic stresses which affects all stages of groundnut growth and finally the yield. Soil amelioration against salinity is a costly and time-consuming procedure. Alternative strategy is to develop salinity-tolerant groundnut ge...

Although salinity in many ecosystems such as salt marshes can be extremely high, an asymmetry in salinity range between experimental studies (relatively narrow) and field conditions (potentially broad) has strongly affected current understanding of plant salinity tolerance. To improve understanding, it is thus important to examine plant tolerances over a broad range of salinities and identify p...

in this study, salinity tolerance of 51 kabuli chickpea genotypes was investigated at vegetative growth phase using 4.5 and 6.5 ds/m salt solution (by adding nacl to 1/2 hoagland solution) and 1/2 hoagland solution (ec= 1.7 ds/m) as control treatment. a split plot design was used in this experiment where the main plot was salinity treatments and the sub plot was genotypes. treatments continued ...

The osmoregulatory ability and salinity tolerance of four species of decapod crustaceans (Decapoda: Natantia) were evaluated to test the degree of physiological adaptation to variations in salinity (2 d exposure to 10, 20, 25 and 32. The ecophysiological salinity tolerance of two penaeids (Metapenaeus joyneri and Penaeus semisulcatus) and two palaemonid species (Palaemon pacificus and Exopalaem...

Halogeton (Halogeton glomeratus) is an invasive species that displaces Gardner's saltbush (Atriplex gardneri) on saline rangelands, whereas, forage kochia (Bassia prostrata) potentially can rehabilitate these ecosystems. Salinity tolerance has been hypothesized as the predominant factor affecting frequency of these species. This study compared relative salinity tolerance of these species, and t...

The giant freshwater prawn, Macrobrachium rosenbergii, is an economically important species. It is a euryhaline shrimp, surviving in wide-range salinity conditions. A change in gene expression has been suggested as an important component for stress management. To better understand the osmoregulatory mechanisms mediated by the gill, a subtractive and suppressive hybridization (SSH) tool was used...

Soil salinity is becoming the key constraints factor to agricultural production. Therefore, the plant especially the crops possessing capacities of salt tolerance will be of great economic significance. The adaptation or tolerance of plant to salinity stress involves a series of physiological, metabolic and molecular mechanisms. Halophytes are the kind of organisms which acquire special salt to...

Plant growth and yields are decreased by salinity, drought and other environmental stress conditions. Soil salinization is one of man’s oldest environmental disasters. The historic records show that many human civilizations declined because of the destruction of crop production by salinization of arable lands. Recent estimates suggest that about 20-25% of the world’s irrigated land is destroyed...
