Salinity is an important ecological factor affecting the osmolality of aquatic animals. Solenaia oleivora endemic and economically freshwater shellfish in China. However, its osmotic response osmoregulatory mechanisms under high salinity stress are still unclear. In this study, S. was exposed to saline water (salinity: 2.2‰) for 3 h, 6 12 24 48 then changes osmolality, ion concentrations, free ...

Despite the fact that most plants accumulate both sodium (Na(+)) and chloride (Cl(-)) ions to high concentration in their shoot tissues when grown in saline soils, most research on salt tolerance in annual plants has focused on the toxic effects of Na(+) accumulation. There have also been some recent concerns about the ability of hydroponic systems to predict the responses of plants to salinity...

in order to evaluate salinity tolerance in 20 sugar bee genotypes, an experiment was conducted in two fields with salinity (ec= 12 ds/m, ph= 7.6) and non-salinity stress, in the form of rcbd at miandoab agricultural research station. different morphological and physiological traits such as root yield, sugar percentage, white sugar percentage, molasses, n, na, k, syrup purity and green cover per...

Invasive plants are recognized for their impressive abilities to withstand adverse environmental conditions however, all invaders do not express the similar abilities. Therefore, survival, growth, nutrient uptake and fecundity of two co-occurring, invasive Physalis species were tested under water and salinity stresses, and different soil textures in the current study. Five different water stres...

Adaptation to environmental stress requires genome-wide changes in gene expression. Histone modifications are involved in gene regulation, but the role of histone modifications under environmental stress is not well understood. To reveal the relationship between histone modification and environmental stress, we assessed the effects of inhibitors of histone modification enzymes during salinity s...

Soil salinity represents an increasing threat to agricultural production. High sodium (Na) concentrations in soils are toxic to most higher plants. More than 40% of irrigated lands worldwide show increased salt levels. Several studies have shown that under saline conditions, Na influx into root cells occurs via Na permeable transporters (Amtmann et al., 1997; Roberts and Tester, 1997; Tyerman e...

We examined the accumulation of organic solutes under optimum growth conditions in 12 species of thermophilic and hyperthermophilic Archaea belonging to the Crenarchaeota and Euryarchaeota. Pyrobaculum aerophilum, Thermoproteus tenax, Thermoplasma acidophilum, and members of the order Sulfolobales accumulated trehalose. Pyrococcus furiosus accumulated di-myo-inositol-1,1(prm1)(3,3(prm1))-phosph...
