the present study was conducted to evaluate the effect of ascorbic acid (asa) as an important antioxidant in alleviation of salt damage in oregano (origanum majorana l.). this research work was carried out at the research greenhouse of ferdowsi university of mashhad. foliar application of asa (0, 100, 200 mg/l) was carried out on the plants that were under salt stresses of 0, 50, 100 and 150 mm...

Entomopathogenic fungi Metarhizium species are generally employed to manage the soil-dwelling stage of insect pests, and known for their rhizocompetency property. Since this fungus is typically recommended use in soil, it could potentially be investigated as a bioinoculant reduce abiotic stress, such salinity, along with improved plant growth promotion. Salt stress tolerance potential native is...

Tomato (Lycpoersicum esculemtum) belongs to the Solanaceae potato family and is an important crop plant. It is relatively resistant to salinity, but in the saline environment growth and production of the plant significantly reduces. On the other hand, the presence of mycorrhiza fungus can improve the adverse effects of salinity. A factorial experiment in a completely randomized design with thre...

Objective: Salt stress is a world-wide problem and soil salinity is common in arid and semi-arid regions. This study was undertaken to investigate salt tolerance in Salsola orientalis in laboratory and natural conditions and recognize the mechanisms that allow it to tolerate these conditions. Methods: This study had two parts of greenhouse and natural habitats. The treatment s...

Pyruvate kinase, lactate dehydrogenase, and phosphoenol pyruvate were purchased from Sigma. Restriction endonucleases, shrimp alkaline phosphatase (SAP), and T4 polynucleotide kinase were from New England Biolabs. Covalently closed circular χ +-3F3H dsDNA (a pBR322 derivative, containing tandem χ-sequences (Anderson et al., 1999)) was purified using a QIAGEN " Maxi kit ". M13mp7 replicative for...

Patch clamp recordings carried out in the inside-out configuration revealed activity of three kinds of channels: nonselective cation channels, small-conductance K(+) channels, and large-conductance anion channels. The nonselective cation channels did not distinguish between Na(+) and K(+). The unitary conductance of these channels reached 28 pS in a symmetrical concentration of 200 mM NaCl. A l...

salinity is one of the major environmental stresses that limit plant growth and productivity. glasswort (salicornia herbacea l.) is one of the native halophytic plants of iran that widely spread in salt areas. the purpose of this study was to determine the physiological and growth responses of s. herbacea to salinity stress. plastic pods (15 cm diameter, 20 cm height) with the silica sand bed w...

An in vitro line of transformed BALB/3T3 mouse fibroblasts was exposed to a 100 mM increase in the NaCl concentration of its growth medium. The rate of growth, as measured by the incorporation of tritiated thymidine, decreased almost 100-fold during the first 24 h of exposure to the hyperosmotic medium and then increased approximately 10-fold during the second 24 h of exposure. Cell counts of c...

salinity is one of the most brutal environmental stresses that hamper crop productivity worldwide approximately 10% of the total land surface is salt affected and about 10 million hectare of agricultural land is lost annually due to salinization and water logging. this study was conducted to determine the ion exchanges in halocnemum strobilaceum and halostachys caspica in saline conditions. the...
