Kabak, yetiştiriciliği ülkemizde ve dünyada yaygın olarak yapılan bir sebze türüdür. Abiyotik stres faktörlerinden tuzluluk, bitkilerin gelişimini verimini önemli derecede azaltmaktadır. Bu çalışma, in vitro koşullarda farklı konsantrasyonlarda (0, 50, 100, 150, 200, 250 mM) NaCl içeren besin ortamının kabak bitkisi gelişimine etkilerini belirlemek amacıyla yapılmıştır. Araştırmada gövde yaş ku...

Macula densa (MD) cells express COX-2 and COX-2-derived PGs appear to signal the release of renin from the renal juxtaglomerular apparatus, especially during volume depletion. However, the synthetic machinery and identity of the specific prostanoid released from intact MD cells remains uncertain. In the present studies, a novel biosensor tool was engineered to directly determine whether MD cell...

Salinity adversely affects plant growth and development, and disturbs intracellular ion homeostasis, resulting in cellular toxicity. Plants that tolerate salinity, halophytes, do so by manifesting numerous physiological and biochemical processes in coordination to alleviate cellular ionic imbalance. The present study was undertaken to analyse the salt tolerance mechanism in Aeluropus lagopoides...

Small unilamellar vesicles composed of phosphatidylserine (PS) and cholesterol at various ratios were employed in studying the effect of cholesterol on Ca2+-induced vesicle aggregation and fusion using the Tb/dipicolinic acid assay. The leakage of preencapsulated Tb3+ was also measured. The analysis of the data provided estimates for the rate of aggregation C11, and the rate of fusion per se, f...

To develop a technique suitable for measuring NaCl taste thresholds in genetic studies, we conducted a series of experiments with outbred CD-1 mice using conditioned taste aversion (CTA) and two-bottle preference tests. In Experiment 1, we compared conditioning procedures involving either oral self-administration of LiCl or pairing NaCl intake with LiCl injections and found that thresholds were...

plasma membrane h+-atpase is a major integral membrane protein with a role in various physiological processes including abiotic stress response. to study the effect of nacl on the expression pattern of a gene encoding the plasma membrane h+-atpase, an experiment was carried out in a completely random design with three replications. a pair of specific primers was designed based on the sequence o...

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...

In this study, the response to salt stress was evaluated in ex vitro acclimated date palm plants, regenerated from culture multiplication. The eighteen-month-old, were irrigated with 0 (control), 150, 300 or 450 mM NaCl solutions (high very high-water salinity). Photosynthesis parameters and antioxidant compounds determined at end of experiment leaves. At 150 NaCl, net CO2 assimilation rate int...

PURPOSE Na,K-ATPase activity increases in lens cells exposed to hypertonic stress. To test whether the increase in activity involves stimulation of Na,K-ATPase expression, dog lens epithelial cells were subjected to hypertonic stress, and the time course of Na,K-ATPase protein and mRNA response was measured. METHODS Primary cultures of dog lens epithelial cells were maintained in isotonic or ...

The objective of the study was to investigate effects salinity stresses (50, 100, 150, 200 and 250 mM NaCl) on germination early seedling growth six cotton varieties (Lydia, Carisma, Flash, BA151, BA525 ST468) under optimum (25°C) low temperature (18°C) conditions. Germination percentage, mean time, index, stress tolerance length, vigor fresh dry weight were investigated. Results showed that le...
