vacuolar h+-translocation pyrophosphatase (v-ppase) and na+/h+ antiporter (v-na+/h+) are important transporters in plant cells and have essential roles against abiotic stresses. in this study, the effects of salt stress were surveyed on the transcription of v-ppase pump and na+/h+ antiporter genes at early times of nacl treatment in roots of halophytic grass leptochloa fusca through the real ti...

AbstractThis study was undertaken to better understand the probable mechanisms of salt stress tolerance induced by seed priming of salicylic acid (SA) in barley. The barley seeds were pre-soaked by SA or water and then sown under different saline watering regimes including 0.62 (tapwater), 5, 10 and 15 dS m-1 in petri dishes and trend of water absorbing, seedling growth, germination rate and pe...

a study of physiological responses of different wheat cultivars to saline conditions can lead to an identification of the main mechanisms in salt tolerance. seven bread wheat cultivars differing in salt tolerance with varying ability of sodium accumulation in their different tissues were employed to assess ion distribution and sodium accumulation under saline conditions. ion distribution and na...

in this study, responses of four canola genotypes to salt stress in germination test and callus culture stages were investigated. the response of genotypes under salinity levels was significantly different. higher salinity resulted in less germination and growth of seedling. after callus culturing on liquid saline media, callus fresh weight and callus induction efficiency were significantly dif...

a factorial experiment based randomized complete block was conducted in order to investigation of two rice (oryza sativa l.) genotypes responses for na+, k+, ca2+, mg2+, clˉ, mn2+, p and total soluble sugars accumulation and compartmentation in leaves 3, 4, 5 and 6 to salt stress. in estimation of the simple correlation between traits, dry weight was negatively correlated with na+ and clˉ. the ...

We examined the importance of the Na+, K(+)-ATPase in cisplatin (DDP) accumulation in 2008 human ovarian carcinoma cells and describe changes in the Na+, K(+)-ATPase in DDP-resistant cells with DDP accumulation defects. Approximately 50% of DDP accumulation was inhibitable by ouabain. DDP accumulation into 2008 cells could be maximally inhibited when cells were preincubated with ouabain for 1 h...

In order to evaluate responses of a pistachio seedling rootstock (Pistacia vera L. cv. Ghazvini) to NaCl induced salinity stress and potential protective role of exogenous spermine and spermidine on NaCl induced salinity stress, a greenhouse experiment was conducted during growing season of 2009. The NaCl treatments, involving 800, 1600, and 3200 mg NaCl per Kg of soil for 90 days, suppressed g...

this study was carried out in the general commission for scientific agricultural research (gcsar) at der ez zour agricultural research center, during 2009- 2010 growing seasons. the role of na+, k+, na+/k+, carbohydrates accumulation of leaves, and sugar content of roots on the osmotic adjustment was studied in 10 sugar beet genotypes (five were monogerms and five were multigerms), under salini...
