introduction: drought stress is one of the main problems in agricultural productions in arid and semiarid regions such as iran. lack of water influences on most of plant physiological processes such as photosynthes, cellular development and uptake and transmission of nutrients in plants. some approaches such as selection of resistance cultivars to drought stress, and selection of dripped irriga...

Mycorrhizal fungi form a mutualistic symbiosis with plants and play an important role in regulating community and ecosystem functioning. These plant-fungal associations are geographically widespread, being found in terrestrial ecosystems ranging from deserts to lowland tropical rain forests to high latitudes. Studies of mycorrhizal community dynamics and activity are important in that these org...

The general objective of this study was to measure the mycorrhizal dependencies of Cupressus and Lavandula species, to assess the contribution of Lavandula species to the mycorrhizal soil infectivity (MSI) and to determine the main effects of the association between a Lavandula species (L. multifida) and Cupressus arizonica on the soil microbial activities, on the growth and the mycorrhizal sta...

The effects of a superphosphate (SP) and a rock phosphate (RP), with equal total P contents, on the growth and mineral nutrition responses of mycorrhizal and nonmycorrhizal cowpea, pigeon pea and groundnut were investigated in a pot experiment using an air-dry gamma ray-sterilized (1.5Mrad) Andisol subsoil. Adequate amounts of micronutrients were added to the pot soils as supplements. The plant...

Arbuscular mycorrhizae (AM) are benefi cial symbionts for plant growth. They are associated with higher plants by a symbiotic association, and benefi t plants in uptake of phosphorus nutrients, production of growth hormones, increase of proteins, lipids and sugars levels, helps in heavy metal binding, salinity tolerance, disease resistance, and even in the uptake of radionuclides. Mycorrhizal g...

The plant growth, phosphate acquisition, Cd translocation, phytochelatins (PCs) production and antioxidant parameters [superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (POD), ascorbate peroxidase (APX), glutathione reductase (GR), glutathione (GSH), ascorbate (ASA) and malonaldehyde (MDA)] were investigated in Cd-hyperaccumulator Solanum photeinocarpum inoculated with Glomus vers...

Myco-heterotrophy is one of the longest-studied aspects of the mycorrhizal symbiosis, but there remain many critical, unanswered questions regarding the ecology and physiology of myco-heterotrophic plants and their associated fungi. The vast majority of all myco-heterotrophs studied to date have exhibited specificity towards narrow lineages of fungi, but it is unclear whether the loss of photos...

water deficit stress permanent or temporary limits the growth and distribution of natural vegetation and performance of plants more than other environmental factors. in order to investigate the effect of drought stress and mycorrhizal-arbuscular fungi inoculation on the growth and yield of savory (satureja hortensis l.) a factorial experiment based on completely randomized design were conducted...

BACKGROUND Global phosphorus (P) reserves are being depleted, with half-depletion predicted to occur between 2040 and 2060. Most of the P applied in fertilizers may be sorbed by soil, and not be available for plants lacking specific adaptations. On the severely P-impoverished soils of south-western Australia and the Cape region in South Africa, non-mycorrhizal species exhibit highly effective a...
