terfezia, picoa and tirmania, so called desert truffles, are mycorrhizal fungi mostly endemic to arid and semi-arid areas of the mediterranean region, where they are associated with helianthemum and carexspecies. the aim of this work was to study the identification, molecular analysis, distribution and hosts of these pezizalean hypogeous fungi in iran. among the specimens, terfezia claveryi, ti...

Many natural and anthropogenic soils are phosphorus (P) limited often due to larger P stocks sequestered in forms of low bioavailability. One the strategies overcome this shortage lies symbiosis plants with mycorrhizal fungi, increasing plant uptake these hardly accessible sources. However, little is known about fungal mediated partitioning differently available forms, which could contribute mo...

Protein biosynthesis in Pisolithus Eucalyptus grandis ectomycorrhiza was related to the stage of ectomycorrhizal development using two-dimensional polyacrylamide gel electrophoresis of proteins labelled by in vivo incorporation of 35S radiolabelled amino acids. Nineteen-day-old seedlings were radiolabelled and the primary root was divided into I-cm segments. With increasing distance from the ti...

Ectomycorrhiza (ECM) communities can be described on a species level or on a larger scale at an ecosystem level. Here we show that the species level approach of successional processes in ECM communities is not appropriate for understanding the diversity patterns of ECM communities at contaminated sites. An ecosystem based approach improves predictability since different biotic and abiotic facto...
