پیشبر Rd29A به وسیله واکنش زنجیری پلیمراز (PCR) و با استفاده از آغازگرهای اختصاصی از گیاه Arabidopsis thaliana همسانه­سازی شد. ناقل دوگانه بیانی pBI-RD-GUS با اتصال توالی RD29A به ژن gus ساخته شد. سازه اخیر به همراه pBI121 با استفاده از Agrobacterium tumefaciens برای تراریختی گیاه توتون مورد استفاده قرار گرفت. ارزیابیهای مولکولی گیاهان تراریخته توتون حضور و فعالیت ژن gus تحت پیشبرهای Rd29A و Ca...

The endogenous gibberellin (GA) and abscisic acid (ABA) contents as an effect of different application times of jasmonic acid (JA) in chard seedlings exposed to salt stress were investigated. Endogenous ABA content was increased by JA treatment after NaCl treatment, rather than after JA application before NaCl treatment. JA application after NaCl treatment caused higher ABA content than treatme...

Previous studies from our laboratories demonstrated that dietary NaCl supplementation in NaCl-sensitive spontaneously hypertensive rats elevates blood pressure, increases peripheral sympathetic nervous system activity, and depresses endogenous norepinephrine stores and turnover in the anterior hypothalamus. These findings suggest that reduced noradrenergic input to sympathoinhibitory neurons in...

Our previous studies demonstrated that chronic dietary NaCl supplementation is associated with significant increases in plasma atrial natriuretic factor in Wistar-Kyoto (WKY) rats but not in NaCl-sensitive spontaneously hypertensive rats (SHR-S). The current study tested the hypotheses that 1) acute volume-induced atrial natriuretic factor release is impaired in SHR-S compared with control NaCl...

Open-celled titanium foams were fabricated by vacuum hot pressing of a blend of Ti and NaCl powders followed by NaCl removal in water. Densification kinetics of the Ti/NaCl blends are measured at 780 ◦C at various pressures (30–50MPa), NaCl volume fractions (30–70%) and NaCl powder sizes (50–500 m). As compared to pure Ti powders, densification kinetics of the blends is faster for relative dens...

Internal friction of deformed oriented NaCl single crystals has been measured as a function of flow stress, strain amplitude, frequency, temperature and divalent doping. In pure NaCl af er deformation a maximum of internal friction PI is observed at low temperatures. With increasing 1+ Sr doping a second but much weaker peak P2 appears at higher temperatures. The dependencies of PI on the...

A halophyte, common glasswort (Salicornia europaea L.), showed no phytotoxic or deficiency symptom at 100 and 300 mM NaCl, whereas plant growth was stunted at 0, 500, and 700 mM NaCl. In addition, the water content was lower within the shoots at 0 mM NaCl, as compared with the range of NaCl treatments. Under NaCl treatment, Naþ levels increased in the shoot and the root, whereas the levels of o...

Component signaling in taste mixtures containing both beneficial and dangerous chemicals depends on peripheral processing. Unidirectional mixture suppression of chorda tympani (CT) nerve responses to sucrose by quinine and acid is documented for golden hamsters (Mesocricetus auratus). To investigate mixtures of NaCl and acids, we recorded multifiber responses to 50 mM NaCl, 1 and 3 mM citric ac...

Effects of gustatory nerve transection on salt taste have been studied extensively in rats and hamsters but have not been well explored in the mouse. We examined the effects of chorda tympani (CT) nerve transection on NaCl taste preferences and thresholds in outbred CD-1 mice using a high-throughput phenotyping method developed in our laboratory. To measure taste thresholds, mice were condition...
