The mutualistic symbiosis between flowering plants and arbuscular mycorrhizal fungi is extremely abundant in terrestrial ecosystems. In this symbiosis, obligately biotrophic fungi colonize the root of the host plants, which can benefit from these fungi by enhanced access to mineral nutrients in the soil, especially phosphorus. One of the main goals of research on this symbiosis is to find plant...

Photosynthesis by leaves and acquisition of water and minerals by roots are required for plant growth, which is a key component of many ecosystem functions. Although the role of leaf functional traits in photosynthesis is generally well understood, the relationship of root functional traits to nutrient uptake is not. In particular, predictions of nutrient acquisition strategies from specific ro...

The roots of the majority of tree species are associated with either arbuscular mycorrhizal (AM) or ectomycorrhizal (EM) fungi. The absorptive roots of tree species also vary widely in their diameter. The linkages between root thickness, mycorrhiza type and nutrient foraging are poorly understood. We conducted a large root ingrowth experiment in the field to investigate how absorptive roots of ...

to study the effect of different arbuscular mycorrhiza fungi on growth performance and water absorption efficiency of osteospermum, a factorial experiment based on a randomized complete block design was conducted in greenhouse. a total of 22 different species of mycorrhizal fungi in symbiosis with the plant studied in this experiment. the results showed that mycorrhiza fungus glomus mossea ca a...

In the present study three cDNA fragments were cloned using degenerate primers for Mn-sod genes and PCR: two showed a high degree of identity with Mn-sods from plants and the third with Fe-sod. Arbuscular mycorrhizal (AM) symbiosis down-regulated their expression pattern under well-watered conditions. In contrast, AM symbiosis in combination with drought stress considerably increased the expres...

Arbuscular mycorrhizal (AM) fungi are root symbionts that can increase or decrease aphid growth rates and reproduction, but the reason by which this happens is unknown. To investigate the underlying mechanisms of this interaction, we examined the effect of AM fungi on the English Grain aphid (Sitobion avenae) development, reproduction, attraction, settlement and feeding behaviour on two natural...

The fungicide benomyl inhibited spore germination and hyphal length of the arbuscular mycorrhizal fungus Glomus mosseae when applied at doses of 21.25 microg/ml (agronomic dose), 10.62 microg/ml and 10 microg/ml. G. mosseae was able to germinate in the presence of 2.12 microg/ml of benomyl, and the percentage of spore germination was unaffected by dosis of 0.1, 0.01 and 0.001 microg/ml of the f...

In this study, the arbuscular mycorrhizal fungus (G. mosseae) and endosymbiont (P. indica) colonized Zea mays were treated with calcium phosphate nanoparticles (CaPNPs) and evaluated for their plant growth promotion efficiency. It was observed that CaPNPs in combination with both G. mosseae and P. indica are more potent plant growth promoter than independent combinations of CaPNPs+G. mosseae,...

The aim of this work was to study the colonization of indigenous arbuscular mycorrhizal fungi (AMF) species in fine-roots of poplar clones. Roots of 7 poplar clones were sampled from a 1-year-old trial established at an industrial site strongly polluted with heavy metals at Balatonfuzfo, Hungary. The poplar clones have shown variable degrees of colonization by AMF, suggesting differential host ...

The present study shows the status of mycorrhization in three test varieties of chickpea. As the results revealed irrespective to the crops when arbuscular mycorrhizal fungi (AMF) were assessed under the influence of soil quality better results were obtained with unsterile soil in comparison to sterile soil. Chickpea variety ICC 11322 showed the best result against the Fusarium wilt and chickpe...
