An increasing area of transgenic Bacillus thuringiensis (Bt) cotton is being planted in saline-alkaline soil in China. The Bt protein level in transgenic cotton plants and its control efficiency can be affected by abiotic stress, including high temperature, water deficiency and other factors. However, how soil salinity affects the expression of Bt protein, thus influencing the control efficienc...

The parasitic dinoflagellate Hematodinium sp. parasitizes blue crabs along the Atlantic seaboard of the United States. Infections in blue crabs have only been reported from waters where salinity is >11 practical salinity units (psu). Blue crabs maintain a hyperosmotic internal concentration at low salinities (0-5 psu), roughly comparable to 24 psu, and should be capable of maintaining an infect...

Soil salinity is generally spatially heterogeneous, but our understanding of halophyte physiology under such conditions is limited. The growth and physiology of the dicotyledonous halophyte Atriplex nummularia was evaluated in split-root experiments to test whether growth is determined by: (i) the lowest; (ii) the highest; or (iii) the mean salinity of the root zone. In two experiments, plants ...

Acclimated and acute rates of oxygen consumption of the American oyster Crassostrea virginica (Gmelin) were measured under 9 salinity-temperature combinations during declining oxygen tensions. In acclimated and non-acclimated individuals the basal rate of oxygen uptake increased significantly with each 10 C" rise in temperature. Multiple regression equations relating exposure and experimental t...

In this study, yeast HOG1 homologue from the root endophyte Piriformospora indica (PiHOG1) was isolated and functionally characterized. Functional expression of PiHOG1 in S. cerevisiae ∆hog1 mutant restored osmotolerance under high osmotic stress. Knockdown (KD) transformants of PiHOG1 generated by RNA interference in P. indica showed that genes for the HOG pathway, osmoresponse and salinity to...

Low-salinity brine injection has emerged as a promising, cost-effective improved oil recovery (IOR) method for waterflooding reservoirs. Laboratory tests and field applications show that low-salinity waterflooding could lead to significant reduction of residual oil saturation. There has been a growing interest with an increasing number of low-salinity waterflooding studies. However, there are f...

Plant samples of Salicornia herbacea were collected from different localities around the northern costal part of Izmir, during the months of June, July, August and September. Salinity and pH of the soils and plants was investigated and the relationship between these parameters tested statistically. The soil salinity values showed that the highest values were obtained in August, but after the ra...

Nile tilapia Oreochromis niloticus is a freshwater fish but can tolerate a wide range of salinities. The mechanism of salinity adaptation at the molecular level was studied using RNA-Seq to explore the molecular pathways in fish exposed to 0, 8, or 16 (practical salinity unit, psu). Based on the change of gene expressions, the differential genes unions from freshwater to saline water were class...

The aim of this study was to investigate the effect of salinity on cadmium (Cd) accumulation and metallothionein (MT) expression in the dogwhelk Nucella lapillus (L.). Adult dogwhelks (shell length: 23.4F1.3 mm) were acclimated to salinity of 33 psu (control), 22 or 11 psu under controlled laboratory conditions (9.5 jC; pH 7.9) for 10 days in a stepwise manner by reducing the salinity by 5.5 ps...

A doubled haploid (DH) population of barley (Hordeum vulgare L.) generated from salinity tolerant genotype CM72 and salinity sensitive variety Gairdner was studied for salinity stress tolerance at germination, seedling emergence and first leaf full expansion growth stages. Germination study was conducted with deionized water, 150 mM and 300 mM NaCl treatments. Seedling stage salinity tolerance ...
