Calmodulin-like (CML) proteins are important Ca(2+) sensors, which play significant role in mediating plant stress tolerance. In the present study, cold responsive calmodulin-like (ShCML44) gene was isolated from cold tolerant wild tomato (Solanum habrochaites), and functionally characterized. The ShCML44 was differentially expressed in all plant tissues including root, stem, leaf, flower and f...

Salinity is one of the major abiotic stresses affecting alfalfa productivity. Developing salinity tolerant alfalfa genotypes could contribute to sustainable crop production. The functions of microRNA156 (miR156) have been investigated in several plant species, but so far, no studies have been published that explore the role of miR156 in alfalfa response to salinity stress. In this work, we stud...

BACKGROUND: Among the environmental stresses soil salinity is a widespread environmental problem that has been found to affect more than 77 million hectares or 5% of the cultivable land of the universe. Potassium has a positive role in plant growth under saline conditions, because this element plays an essential role in photosynthesis, osmo regulatory adaptations of plant to wa...

The use of soil and irrigation water with a high content of soluble salts is a major limiting factor for crop productivity in the semi-arid areas of the world. While important physiological insights about the mechanisms of salt tolerance in plants have been gained, the transfer of such knowledge into crop improvement has been limited. The identification and exploitation of soil microorganisms (...

stevia rebaudiana bertoni is a medicinal, perennial and herbaceous plant from asteraceae family with sweet glycosides in its leaves. salinity stress is one of the important limiters in agricultural productions. salinity influences the growth and development of plant by effect on more activities in physiological and morphological characteristics. to study the effect of salinity on morphological ...

Phytoremediation is an eco-friendly method for removal of pollutants, which can be relied upon as a sustainable technology, if implemented under optimum conditions of plant growth. The effectiveness of water hyacinth, a topical weed, for the removal of Zinc (Zn) and Chromium (Cr) ions from aqueous solutions has been presented in this article. The potential of this plant in removing metals by ph...

abstract plants are exposed to stressful environmental conditions in the process of growth and development. one of the most important stresses is the salt stress which can limit the plant’s growth and yield. plants symbiosis with arbuscular mycorrhizal fungi in salt conditions can affect the plant’s yield as well as growth parameters. the plant’s growth in salt stressful conditions might be red...

present study was conducted to investigate the effects of different osmotic potentials (0.0 mpa, -0.4 mpa, -0.8 mpa and -1.2mpa) induced by nacl and polyethylene glycol-6000(peg) as salinity and drought stress respectively on germination and early growth of two inbred lines of maize (mo17 and b73). the objective was to compare the germination ability between tow maize inbred lines in salt and d...

Plant growth is affected by the osmotic stress as well as toxicity of salt in leaves. In order to study of salt stress effects on stomatal conductance and growth rate and relationship between them as wells osmotic and Na-specific effects on these traits, four bread wheat genotypes differing in salt tolerance were selected. Salinity was applied when the leaf 4 was fully expanded. Sodium (Na) con...
