to evaluate the effect of arbuscular mycorrhiza (glomus mosseae) under salt stress on physiological and some nutrient absorption in new guinea impatiens (impatiens hawkeri), an experiment established in complete random design with three replications (three pots for each replication) in greenhouse in shahrekord university in 2014. treatments were inoculation of substrate with three levels of arb...

Red mud or bauxite residue is a highly alkaline toxic by-product that generated during the production of aluminum by Bayer’s process. Around 1.5 tons residues are produced for generating 1 ton alumina. The toxicity major catastrophe due to its disposal management as it limits growth plant species because high alkalinity and salinity. In present study, bioprospects carried through cyanobacterial...

the effects of arbuscular mycorrhizal fungi on nitrogen concentration of berseem clover were examined in contaminated soil with cadmium. examined factors included: levels of arbuscular mycorrhizal fungi inoculation ( glomus mosseae ) (with and without inoculation), and different levels of soil contamination by cadmium (0, 5, 10, 20, 40 and 80 mg.kg-1). the results showed that the effects of cad...

this study was conducted to determine soil properties that correlate with the arbuscular mycorrhizal fungal (amf) spore numbers in semiarid calcareous soils of hamadan province in northwestern of iran. soil samples from six sites managed differently were collected from a 0 to 30 cm depth. the results showed that land use and management systems had a significant effect on amf spore number in soi...

Salinization has led to the deterioration of ecological environment, affected growth plants, and hindered development agriculture forestry. Arbuscular mycorrhizal (AM) fungi, as important soil microorganisms, play significant physiological roles in promoting plant nutrient absorption improving structure. Puccinellia tenuiflora (Turcz.) Scribn. et Merr. Songnen saline-alkaline grassland was sele...

There is increasing interest worldwide in the maintenance of soil quality and remediation strategies for management of soils contaminated with pollutants including heavy metals. The protective effects of arbuscular mycorrhizas on host plants under conditions of Zn contamination have raised the prospect of utilizing the mutualistic association in soil revegetation programmes, and consequently re...

The Stochastic Calculus of Wrapped Compartments (SCWC) is a recently proposed variant of the Stochastic Calculus of Looping Sequences (SCLS), a language for the representation and simulation of biological systems. In this work we apply SCWC to model a newly discovered ammonium transporter. This transporter is believed to play a fundamental role for plant mineral acquisition, which takes place i...

Despite the importance of sulfur (S) for plant nutrition, the role of the arbuscular mycorrhizal (AM) symbiosis in S uptake has received little attention. To address this issue, 35S-labeling experiments were performed on mycorrhizas of transformed carrot (Daucus carota) roots and Glomus intraradices grown monoxenically on bicompartmental petri dishes. The uptake and transfer of 35SO4(2-) by the...
