Plants rapidly release photoassimilated carbon (C) to the soil via direct root exudation and associated mycorrhizal fungi, with both pathways promoting plant nutrient availability. This study aimed to explore these pathways from the root's vascular bundle to soil microbial communities. Using nanoscale secondary ion mass spectrometry (NanoSIMS) imaging and (13) C-phospho- and neutral lipid fatty...

introduction in recent years, by increasing human knowledge and using different technology on food production, human concerns have increased on safety of food products especially medicinal crops. in order to achieve healthy food production, application of ecological inputs such as organic and biological fertilizers are inevitable. organic fertilizers are fertilizer compounds that contain one or...

to evaluate the influence of arbuscular mycorrhizal inoculation on growth, yield and minituber production of potato plantlets, a pot experiment was conducted using a factorial based on completely randomized design with four replications. the factors were mycorrizal inoculation (non-inoculated and inoculated with glomus mosseae, glomus etunicatum and mixed of them) and two potato cultivars (agri...

Roots constitute important plant organs for water and nutrient uptake. They, however, also release a wide range of carbon compounds of lowmolecular weight. This release can amount up to 30% of total net fixed carbon (Smith and Read 2008; Rovira 1991) and forms the basis for an environment inhabited by a highly diverse and active microbial community, the rhizosphere (Hiltner 1904; Hartmann et al...

Arbuscular mycorrhizal and ectomycorrhizal symbioses are among the most important drivers of terrestrial ecosystem dynamics. Historically, the two types of symbioses have been investigated separately because arbuscular mycorrhizal and ectomycorrhizal plant species are considered to host discrete sets of fungal symbionts (i.e., arbuscular mycorrhizal and ectomycorrhizal fungi, respectively). Non...

Fires are critical pathways of carbon loss from boreal forest soils, whereas microbial communities form equally critical controls over carbon accumulation between fires. We used a chronosequence in Alaska to test Read’s hypothesis that arbuscular mycorrhizal fungi should dominate ecosystems with low accumulation of surface litter, and ectomycorrhizal fungi should proliferate where organic horiz...

Arbuscular mycorrhizal fungi (AMF) are expected to be one of the key drivers determining the diversity of natural plant communities, especially in nutrient-poor and dry habitats. Several previous studies have explored the importance of AMF for the composition of plant communities in various types of habitats. Surprisingly, studies of the role of AMF in nutrient-poor dry grassland communities do...

Arbuscular mycorrhizal fungi (AMF) form a mutually beneficial symbiosis with plant roots providing predominantly phosphorus in the form of orthophosphate (Pi) in exchange for plant carbohydrates on low P soils. The goal of this work was to generate molecular-genetic evidence in support of a major impact of the mycorrhizal Pi uptake (MPU) pathway on the productivity of the major crop plant maize...
