This study assessed salt sensitivity, analyzing the effects of an increased saline intake on hemodynamic, morphological, and oxidative stress and renal variables in experimental thyroid disorders. Six groups of male Wistar rats were used: control, hypothyroid, hyperthyroid, and the same groups treated with salt (8% via food intake). Body weight, blood pressure (BP), and heart rate (HR) were rec...

Ameliorative effect of exogenously applied glycinebetaine (GB) on photosynthetic capacity of two wheat cultivars differing in salt tolerance grown under salt stress was assessed. Plants were grown under field conditions at 2.84, 15 dS/m in split-split plot design. Different levels of GB (no spray NS, 0.1% Tween 20 solution, 50 and 100 mM GB in 0.1% Tween 20 solution) were exogenously applied as...

in order to identify and selection salt tolerant hybrids based on tolerance indices, 17 sugar beet three-way cross hybrids produced by crosses between 17 salinity improved s1 pollinators and a cytoplasmic male sterile (cms) single cross as female, along with three control genotypes were grown in 2007 in rudasht station (isfahan) under saline (12 ds/m and 8 ds/m for water and soil) and non-salin...

High salinity seriously affects the production of chrysanthemum, so improving the salt tolerance of chrysanthemum becomes the focus and purpose of our research. The WRKY transcription factor (TF) family is highly associated with a number of processes of abiotic stress responses. We isolated DgWRKY4 from Dendranthema grandiflorum, and a protein encoded by this new gene contains two highly conser...

Salinity is one of the major limitations for food production worldwide. Improvement of plant salt-stress tolerance using plant-growth promoting rhizobacteria (PGPR) has arisen as a promising strategy to help overcome this limitation. However, the molecular and biochemical mechanisms controlling PGPR/plant interactions under salt-stress remain unclear. The main objective of this study was to obt...

Salinity stress challenges agriculture and food security globally. Upon salt stress, plant growth slows down, nutrients are recycled, osmolytes are produced, and reallocation of Na+ takes place. Since autophagy is a high-throughput degradation pathway that contributes to nutrient remobilization in plants, we explored the involvement of autophagic flux in salt stress response of Arabidopsis with...

salt stress negatively impacts crops yield throughout the world. nine varieties of potato (solanum tuberosum l.) were screened for salt stress tolerance by measuring in-vitro growth of the aerial plant parts, as well as roots. salt stress was evaluated by adding 25, 50, 75, 100, 125, 150 and 200 mm of nacl to murashige- skoog (ms) medium and compared to ms medium without nacl. plant length and ...

The present work aimed at investigating changes in growth and some metabolic activities in NaCl-stressed bean plants, and assessing the role of ascorbic acid to alleviate these changes. The field experiment was carried out to study the response of presoaked fava bean seeds (Vicia fava cv. Misr 2) in freshly prepared ascorbic acid (50 ppm ≈ 0.3 mM; as recommended dose as described by  El-Tayeb, ...

to improve bread wheat salt tolerance, new genetic sources of salt tolerance are indispensable, and this requires a screening of wheat germplasm. in order to evaluate bread wheat germplasm, 34 accessions including; hexaploid wheats (aabbdd), tetraploid (aabb) and wild relative diploids (dd and aa genome) collected from different regions of iran were evaluated under normal vs. salinity stress (n...
