The majority of land plants live in symbiosis with arbuscular mycorrhizal fungi from the phylum Glomeromycota. This symbiosis improves acquisition of phosphorus (P) by the host plant in exchange for carbohydrates, especially under low-P availability. The symbiosome, constituted by root cortex cells accommodating arbuscular mycorrhizal fungal hyphae, is the site at which bi-directional exchange ...
One of the most important limiting factors of crop growth in the arid and semi-arid regions is water deficit. Mycorrhizal fungi is one of the most important microorganisms in the rhizosphere. The effects of these fungi apply via changes on some of the characteristics of roots and nutrients uptake in host plants under drought conditions. In order to evaluate the effect of arbuscular mycorrhizal ...
A green house experiment was conducted to investigate the effect of arbuscular mycorrhiza inoculation on plant growth and uptake of mineral nutrition in Ipomoea aquatica considering the objective of using environmental friendly biofertilizer instead of chemical fertilizer. A common leafy vegetable plant Ipomoea aquatica was grown with mycorrhiza and without mycorrhiza for 42 days. After harvest...
Plant cells engage in mutualistic and parasitic endosymbioses with a wide variety of microorganisms, ranging from Gram-negative (Rhizobium, Nostoc) and Gram-positive bacteria (Frankia), to oomycetes (Phytophthora), Chytridiomycetes, Zygomycetes (arbuscular mycorrhizal fungi) and true fungi (Erysiphe, ascomycete; Puccinia, basidiomycete). Endosymbiosis is characterised by the 'symbiosome', a com...
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...
It is hoped that mycorrhiza will increase plant P uptake, and the degree of infection (%) roots in ultisol soil application arbuscular mycorrhizal fungi to various animal feeds determine effect phosphorus (P) uptake on plants so absorption by affected. . This research was conducted from March 2022 October land Faculty Agriculture, University Community Development. design uses a completely rando...
This study was conducted to assess the effects of two species of arbuscular mycorrhiza fungi (Glomus mosseae and G. intraradices) on growth of young plantlets of two olive cultivars (Koroneiki and Valanolia). Recently rooted cuttings were inoculated with the mycorrhiza, planted in pots containing sterile soil and located in the greenhouse. Eighteen months following inoculation, some morphologic...
This research was conducted to evaluate effects of mycorrhiza fungi and nano zinc oxide on agro physiological traits of wheat under salinity stress based on factorial experiment according complete randomized block design with three replications under greenhouse condition at 2014. Treatments included salinity in three levels [no-salt (S0) or control, salinity 40 (S1) and 80 (S2) mM NaCl], two le...
Phosphorus and nitrogen are essential nutrient elements that are needed by plants in large amounts. The arbuscular mycorrhizal symbiosis between plants and soil fungi improves phosphorus and nitrogen acquisition under limiting conditions. On the other hand, these nutrients influence root colonization by mycorrhizal fungi and symbiotic functioning. This represents a feedback mechanism that allow...
One of the new methods for optimum management and increasing the efficiency of water resources utilization in agricultural uses is the use of irrigation methods. Considering the importance of this issue, this research was carried out to determine the effect of mycorrhizal fungi on the yield of sunflower cultivars under drought tension conditions and as split split plots based on randomized comp...
