This experiment was carried out to study the effect of humic acid and growth promoting bacteria on uptake of cadmium heavy metal by annual alfalfa (Medicago scutellata L.). The experiment was arranged in pot experiment conditions in Isfahan, Iran in 2011. A factorial design was used based on completely randomized block design with four replications. Experimental treatments were humic acid and g...

Sorghum [Sorghum bicolor (L.) Moench] is a multipurpose food crop that can adapt to climate change. productivity be increased by applying chemical fertilizers and arbuscular mycorrhiza fungi (AMF). This research aimed assess the effect of AMF application N P concentration gradients support Super 2 KS sorghum accession growth. The plants were grown in sterilized zeolite (coarse fine) inoculated ...

Glomalean fungi induce and colonize symbiotic tissue called arbuscular mycorrhiza on the roots of most land plants. Other fungi also colonize plants but cause disease not symbiosis. Whole-transcriptome analysis using a custom-designed Affymetrix Gene-Chip and confirmation with real-time RT-PCR revealed 224 genes affected during arbuscular mycorrhizal symbiosis. We compared these transcription p...

The effects of saprobe and arbuscular mycorrhizal (AM) fungi on growth, chlorophyll and N, P and K content of Eucalyptus globulus Labill. growing in soil contaminated by heavy metals in the presence or absence of Glycine max were investigated. Glomus mosseae and Glomus deserticola increased dry weight, shoot length, total N, P and K concentration and the quantity of chlorophyll in E. globulus s...

Arbuscular mycorrhizal fungi (AMF) represent an ecologically important and evolutionarily intriguing group of symbionts of land plants, currently thought to have propagated clonally for over 500 Myr. AMF produce multinucleate spores and may exchange nuclei through anastomosis, but meiosis has never been observed in this group. A provocative alternative for their successful and long asexual evol...

The selection of genotypes under high soil fertility may alter the effectiveness of mycorrhizal symbioses naturally forming between crop plants and the mycorrhizal fungi residing in cultivated fields. We tested the hypothesis that the mycorrhizal symbiosis of 5 landraces functions better than the mycorrhizal symbiosis of 27 cultivars of durum wheat that were bred after the development of the fe...

The role of arbuscular mycorrhizal fungi (AMF) on cadmium (Cd) accumulation and on the possible attenuation of Cd stress was studied in maize plants (Zea mays L. var. Exceller). Plants inoculated or not with Glomus macrocarpum were exposed to Cd (0-20 μmol L-1), at two P levels (5 and 10 mg L-1) in the nutrient solution. The experiment was conducted in a hydroponic system, using a randomized 2 ...

Glomus mosseae, a representative species of Endogonaceae (Phycomycetes) able to form vesicular-arbuscular mycorrhiza, was investigated for phytohormone production. Spores of G. mosseae were axenically germinated in water, and the resultant mycelial growth was assayed by standard procedures for extracting plant hormones from microbial cultures. Paper partition chromatography and specific bioassa...

in order to evaluate arbuscular mycorrhiza (glomuss mossea) and mycorrhiza-like (piriformospora indica) effects on yield, yield components and some morphological (cv. azar 2) traits of wheat (triticum aestivum l.) under water deficit stress, a pot experiment was conducted as factorial experiment based on completely randomized design with four replications. treatments were drought stress at thre...
