Salinity represents a critical environmental factor for all aquatic organisms, including fishes. Environments of stable salinity are inhabited by stenohaline fishes having narrow salinity tolerance ranges. Environments of variable salinity are inhabited by euryhaline fishes having wide salinity tolerance ranges. Euryhaline fishes harbor mechanisms that control dynamic changes in osmoregulatory ...
Soil salinity problems are widespread around the globe with increased risk of spreading over the years. The fungus Piriformospora indica, identified in Indian Thar desert, colonizes the roots of monocotyledon plants and provides resistance towards biotic as well as abiotic stress conditions. We have identified a cyclophilin A-like protein from P. indica (PiCypA), which shows higher expression l...
To study the variation of plant traits related to stress tolerance in tolerant and sensitive barley cultivars under salt stress conditions, an experiment was carried out as factorial arrangements in completely randomized design in Payame Noor University of Mahabad, Iran in 2018. Application of salinity stress of 250 mM of sodium chloride started from tillering stage, and leaf samples were taken...
Plant growth and development are adversely affected by salinity – a major environmental stress that limits agricultural production. This chapter provides an overview of the physiological mechanisms by which growth and development of crop plants are affected by salinity. The initial phase of growth reduction is due to an osmotic effect, is similar to the initial response to water stress and show...
Ethylene has been regarded as a stress hormone to regulate myriad stress responses. Salinity stress is one of the most serious abiotic stresses limiting plant growth and development. But how ethylene signaling is involved in plant response to salt stress is poorly understood. Here we showed that Arabidopsis plants pretreated with ethylene exhibited enhanced tolerance to salt stress. Gain- and l...
Saplings of Eucalyptus camaldulensis Dehn. Clone 4544, irrigated with water of differing salinities (2 to 28 dS m-1) and boron concentrations (1 to 30 mg l-1), integrated the history of these stresses through the discrimination of stable isotopes of carbon in leaf and woody tissues. Carbon isotope discrimination (delta) was reduced primarily by salinity. Decreases in discrimination in response ...
Salinity tolerance is an important quality for European rice grown in river deltas. We evaluated the salinity tolerance of a panel of 235 temperate japonica rice accessions genotyped with 30,000 SNP markers. The panel was exposed to mild salt stress (50 mM NaCl; conductivity of 6 dS m-1) at the seedling stage. Eight different root and shoot growth parameters were measured for both the control a...
Soil salinity is a major abiotic stress that results in considerable crop yield losses worldwide. However, some plant genotypes show a high tolerance to soil salinity, as they manage to maintain a high K+/Na+ ratio in the cytosol, in contrast to salt stress susceptible genotypes. Although, different plant genotypes show different salt tolerance mechanisms, they all rely on the regulation and fu...
Utilization compounds like salicylic acid is one of the ways to control the salinity and reduce the damage of salinity. Salicylic acid is a phenolic compound plays a role as signaling molecule in plant tolerance system, to protect plants against stresses. The experiment was done to evaluate the effect of salinity (0, 5, 50, 100 and 200 mM) and salicylic acid (0, 100, 200 and 300 μM) on t...
Response to a high salinity treatment of 300 mM NaCl was studied in a cultivated barley Hordeum vulgare Syrian cultivar Tadmor and in a halophytic wild barley H. marinum. Differential salinity tolerance of H. marinum and H. vulgare is underlied by qualitative and quantitative differences in proteins involved in a variety of biological processes. The major aim was to identify proteins underlying...
