The study aimed to examine the protective effect of hydrogen sulfide (H2S) on high-salt-induced oxidative stress and myocardial hypertrophy in salt-sensitive (Dahl) rats. Thirty male Dahl rats and 40 SD rats were included in the study. They were randomly divided into Dahl control (Dahl + NS), Dahl high salt (Dahl + HS), Dahl + HS + NaHS, SD + NS, SD + HS, SD + HS + NaHS, and SD + HS + hydroxyla...

Under high salt conditions, plant growth is severely inhibited due to both osmotic and ionic stresses. In an effort to dissect genes and pathways that respond to changes in osmotic potential under salt stress, the expression patterns were compared of 460 non-redundant salt-responsive genes in barley during the initial phase under osmotic versus salt stress using cDNA microarrays with northern b...

this study investigated intra-specific variation in the growth parameters and dry mat-ter partitioning of sugar beet cultivars at different levels of salinity (0, 50, 150, 250 and 350 mm nacl + cacl2 in 5:1 molar ratio) using four cvs, one british (madison) and three iranian cvs (7233-p12, 7233-p21 and 7233-p29). the plants were grown in a controlled greenhouse environment for about 18 weeks. a...

abstract millets are important agricultural crops for arid regions due to short life span and their resistance to salinity and drought conditions. in iran, three main species of millets including proso millet (panicum miliaceum), foxtail millet (setaria italica) and pearl millet (pennisetum glaucum) are cultivated in shouthern khorasan province, eastern iran. in order to assess inter-specific g...

As a soil bacterium also found in estuarine and marine habitats, Bacillus subtilis has evolved various sensing and adaptation systems in order to face salt stress conditions. Among these regulatory mechanisms is the DegS-DegU signal transduction system, which was previously shown to be stimulated by high salt concentrations. A search for promoters regulated in response to salt stress led to the...

Ethylene has been regarded as a stress hormone to regulate myriad stress responses. Salinity stress is one of the most serious abiotic stresses limiting plant growth and development. But how ethylene signaling is involved in plant response to salt stress is poorly understood. Here we showed that Arabidopsis plants pretreated with ethylene exhibited enhanced tolerance to salt stress. Gain- and l...

Populus euphratica Oli. is a salt-tolerant species that can cope with up to 450 mM NaCl under hydroponic conditions and can tolerate high accumulations of Na+ and Cl- in roots and leaves when grown in 300 mM NaCl. Transcript responses to salt stress and recovery were monitored by microarray hybridization of 315 cDNAs preselected by suppression subtractive hybridization. Transcripts of a heat-sh...

Salt stress is one of the most common stresses in agricultural regions worldwide. In particular, sugarcane is affected by salt stress conditions, and no sugarcane cultivar presently show high productivity accompanied by a tolerance to salt stress. Proteomic analysis allows elucidation of the important pathways involved in responses to various abiotic stresses at the biochemical and molecular le...
