Understanding the mechanism of salt tolerance in alfalfa (Medicago sativa L.)
… saline growth condition. Understanding of the salt tolerance mechanism and identification of genes responsible for salt tolerance is critical for the development of salt tolerant alfalfa cultivars. We investigated the morphological, physiological and genetic variation of salt tolerant ‘Halo’ …

A study of salt tolerance in Arabidopsis thaliana and Hordeum vulgare
… work was to compare the cellular processes in salt tolerant and salt sensitive plants cells to gain insight into the mechanisms that confer halotolerance. Halotolerant and salt sensitive cell lines were derived from the model glycophyte Arabidopsis thaliana; in addition cell suspension cultures …

Physiological and molecular mechanisms of salt tolerance in barley (Hordeum vulgare L.)
… physiological and molecular mechanisms of salt tolerance. Using the mRNA differential display technique, 21 cDNA fragments were cloned from young leaves, 10 of them had homologues from GenBank. A leucine zipper transcription factor gene (B 15/B20) was upregulated in Golden Promise and …

Adaptation in a Changing World: Evolutionary mechanisms of salt tolerance in a coastal amphibian
… research are to (1.) examine the extent that salt-exposed, coastal frog populations are diverging from salt-naïve, inland populations in response to saltwater exposure across life stages, (2.) determine the molecular and life history mechanisms that permit this species to persist in brackish …

Nitrilase 2: insight into its regulation in Arabidopsis and its potential for improving maize salt tolerance
… the growing population, we need to improve crop salt tolerance. To do this, we need a better understanding of inherent plant molecular responses to salt stress in order to engineer crops with enhanced salt tolerance. Previously, our group has shown that in Arabidopsis, salt-specific genes are …

Characterization and molecular cloning of sos3: A gene important for salt tolerance and potassium nutrition in higher plants
… the components (genes) that are important for salt tolerance in Arabidopsis. Identification and characterization of such genes might provide insights into why these genes are important, and how these genes function in salt response and salt tolerance in higher plants. During my dissertation …

Quantitative Trait Loci (QTL) for Salt Tolerance in Soybean and Physiological Response to Salt Stress During Early Growth Stage
… as a source of high–quality protein and oil. Salt stress is one of the main abiotic stresses causing significant yield losses in soybean, which is considered a moderately salt–sensitive crop. Breeding selection is a promising strategy to improve salt tolerance as soybean germplasm display wide …

Cloning and Characterization of the Salt Overly Sensitive 1 (SOS1) Gene in Chenopodium quinoa WILLD.
Salt tolerance is a commercially important trait that affects plant species around the globe. Cellular response to saline environments is a well studied but complex system that is far from being completely understood. The SALT OVERLY SENSITIVE 1 (SOS1) gene is a critical component of salt tolerance …

Improving salt stress resistance in cereals
… of agriculturally important crops world-wide. Tolerance to salt stress is variable for different plants and involves integration of various physiological and biochemical mechanisms. This thesis investigates the role in salt tolerance of various transporter genes in important agricultural cereal …

Analysis of AtNHX1-expressing transgenic cotton under high salt conditions and in the field
… factors in crop productivity. To improve the salt tolerance in crops, one approach is to increase the solute concentration in the vacuoles of plant cells by sequestering sodium ion (Na+) into the vacuoles of plant cells. Consequently, it would reduce the toxicity of high Na+ in the cytoplasm …

Characterization of ESl47, a salt stress regulated protein kinase from Lophopyrum elongatum
… investigated to elucidate its potential role in salt tolerance and salt stress response. The yeast two-hybrid system was used to screen a cDNA Arabidopsis library and identify proteins that interact with the ESI47 kinase. Six partial DNA sequences encoding a 33 kDa oxygen-evolving enhancer …

Isolation of psychrophilic halophiles from the Antarctic polar desert
… Sound, Antarctica, contained bacteria showing salt tolerance or requirement. Soils were plated by the spread plate method on soil extract-peptone-yeast extract media to which sodium chloride had been added in concentrations from 0 to15 per cent (w/v). Bacteria isolated from these media at 2 °C, …

The Phenotypic Effects and Transcript Response of Salt Stress, the Impact of Viral Infection on Salt Stress Symptoms, and the Effect of Salt Stress on Soybean Virus Vector Activity in Soybean Varieties That Vary in Chloride Uptake
… worldwide, understanding the mechanisms for salt tolerance in plants is important to reduce yield loss due to salt stress. Soybean, <italics>Glycine max </italics> (L.) Merr., genotypes differ in chloride uptake with genotypes that take up chloride into foliar tissues tending to be …
