Abiotic stress has a growing impact on plant growth and agricultural activity worldwide. Specific plant growth promoting rhizobacteria have been reported to stimulate growth and tolerance to abiotic stress in plants, and molecular mechanisms like phytohormone synthesis and 1-aminocyclopropane-1-carboxylate deamination are usual candidates proposed to mediate these bacterial effects. Paraburkhol...

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 ...

Soils are delicate structures, and careless agricultural practices can destroy them. Crop decline resulting from increased soil salinity can be traced back thousands of years to Sumer and Babylonia. There, the original “Fertile Crescent” eventually turned into desert, destroyed by deforestation, unwise planting, and irrigation-induced soil salinity. Such decline in soil productivity also was ev...

INTRODUCTION Salinity is one of the major abiotic stresses affecting crop production via adverse effects of osmotic stress, specific ion toxicity, and stress-related nutritional disorders. Detrimental effects of salinity are also often exacerbated by low oxygen availability when plants are grown under waterlogged conditions. Developing salinity-tolerant varieties is critical to overcome these p...

continuous desertification of arable lands mandates use of low quality/ saline water for irrigation, especially in regions experiencing water shortage. using low quality/ saline water for irrigation imposes more stress on plants that are already under stress in these regions. thus, a logical solution will be to find a salt/ drought-tolerant plant species that will survive/sustain under such str...

salinity tolerance is a genetically and physiologically complex trait, controlled by quantitative trait loci (qtls). in order to map the qtls associated with agronomic and physiological traits, 149 doubled haploid lines derived from a cross between clipper (salt susceptible) and sahara 3771 (salt tolerant) barley genotypes were evaluated under natural saline-stress and non-stress conditions usi...

a solution culture experiment was conducted to evaluate the salinity tolerance of 15 tomato genotypes in hoagland’s nutrient solution with three levels of nacl (0, 75, and 150 mm). the experiment was conducted in completely randomized design with three replicates. after 30 days of imposition of salt stress, gas exchange parameters including transpiration rate, stomatal conductance, co2 assimila...
