soil and water salinity are amongst the severe and progressive problems worldwide which affects most cropland areas of iran. using endophytic microorganisms (which are amongst the most important soil microorganisms) to alleviate the detrimental effect of environmental stresses such as salinity is recently globally considered. in order to test the effects of azospirillum strains and fungus pirif...
Our objective is to test selected mycorrhizal complexes verify the contribution of symbiosis as a biological tool promoting development argan tree under hostile conditions. In addition, this study aims assess impact soil drought caused by stopping watering young plants inoculated with strains fungal indigenous species in comparison non-inoculated plants. Under conditions water deficit stress, m...
Annexins are a family of calcium- and membrane-binding proteins that are important for plant tolerance to adverse environmental conditions. Annexins function to counteract oxidative stress, maintain cell redox homeostasis, and enhance drought tolerance. In the present study, an endogenous annexin, STANN1, was overexpressed to determine whether crop yields could be improved in potato (Solanum tu...
We have characterized the growth responses of Arabidopsis thaliana seedlings to water deficit. To manipulate the water potential, we developed a method whereby the nutrient-agar medium could be supplemented with polyethylene glycol (PEG 8000); PEG was introduced into gelled media by diffusion, which produced media with water potential as low as -1.6 MPa. For dark-grown plants, hypocotyl growth ...
One of the most important limiting factors of crop growth in the arid and semi-arid regions is water deficit. Mycorrhizal fungi is one of the most important microorganisms in the rhizosphere. The effects of these fungi apply via changes on some of the characteristics of roots and nutrients uptake in host plants under drought conditions. In order to evaluate the effect of arbuscular mycorrhizal ...
A moderate water deficit stress (S1) applied 10 days after anthesis was found to induce acclimation to a subsequent more severe drought stress (S2) in Solanum lycopersicum L.. When plants were pretreated with S1, and then subjected to S2, fruit water status remained similar to controls. In contrast, S2 induced a decrease in both parameters of water status and diameter of fruits from non-acclima...
Antioxidant response of cowpea co-inoculated with plant growth-promoting bacteria under salt stress.
Soil salinity is an important abiotic stress worldwide, and salt-induced oxidative stress can have detrimental effects on the biological nitrogen fixation. We hypothesized that co-inoculation of cowpea plants with Bradyrhizobium and plant growth-promoting bacteria would minimize the deleterious effects of salt stress via the induction of enzymatic and non-enzymatic antioxidative protection. To ...
in order to assess drought tolerance of mycorrhizal petunia plants (petunia hybrida cv. mix), a greenhouse experiment was carried out with two different mycorrhizae species (glomus mosseae and glomus intraradices) applied singly or in combination at two phosphorous (p) levels (0 and 100 mg kg-1 dry soil) and three irrigation regimes (100% field capacity (fc) as control, 75% fc producing moderat...
Drought is one of the most important environmental factors limiting the cultivation of ornamental plants in the green space. The effects of spermidine and salicylic acid on hollyhock (Alcea rosea L.)under drought stress were investigated. At first, the plants were sprayed with 3 doses of spermidine and 3 doses of salicylic acid (control, 100, 200 and 400 μM) for three consecut...
In this study, ion exchanges in eggplant plants exposed to drought, salt, and combined stress were researched. While drought-stressed irrigated at 60% FC, salt-stressed with water containing 50 mM sodium chloride (NaCl). Plants under (NaCl) FC. The remained conditions for 90 days, after which they harvested evaluated their content. Ca2+, K+ Mg2+ contents the shoot root decreased significantly s...
