sodium/proton exchangers (nhx) are key players in plant responses to salinity and have a central role in establishing ion homeostasis. nhxs can be localized in tonoplast or plasma membranes, where they exchange sodium ions for protons, resulting in the removal of ions from the cytosol into vacuole or extracellular spaces. in the present study, the expression pattern of the gene encoding na+/h+ ...
در این تحقیق اثر سالیسیلیک‌اسید و پنکونازول به تنهایی و به صورت همزمان بر برخی ویژگی‌های فیزیولوژیکی و مولکولی گلرنگ تحت تنش شوری مورد بررسی قرار گرفت. تیمارهای کلریدسدیم (0، 100 و 200 میلی‌مولار)، سالیسیلیک‌اسید (1mM) و پنکونازول (15mg/l) به مدت 21 روز بر گیاهان اعمال شد. سپس برگ‌های گیاهان جمع‌‌آوری شده و در یخچال در دمای 70- درجه سانتی‌گراد نگهداری شد. نتایج حاصل نشان داد که محتوای پروتئین ت...
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...
Petal color change in morning glory Ipomoea tricolor cv. Heavenly Blue, from red to blue, during the flower-opening period is due to an unusual increase in vacuolar pH (pHv) from 6.6 to 7.7 in colored epidermal cells. We clarified that this pHv increase is involved in tonoplast-localized Na+/H+ exchanger (NHX). However, the mechanism of pHv increase and the physiological role of NHX1 in petal c...
Water-related stress is considered a major type of plant stress. Osmotic stress, in particular, represents the common part of all water-related stresses. Therefore, plants have evolved different adaptive mechanisms to cope with osmotic-related disturbances. In the current work, two grapevine cell lines that differ in their osmotic adaptability, Vitis rupestris and Vitis riparia, were investigat...
