Soil microorganisms play a central role in biological soil functioning. One of the beneficial microbiota that has symbiotic association with most plants is arbuscular mycorrhizal fungi (AMF). Nevertheless, little known about impact cover crops—widely used conservation agriculture or organic farming—on native fungi. This study was conducted Southern France, 20-year-old walnut orchards, where fab...

in order to investigate the response of mycorrhizal fungi to different kinds of fungicides and phytohormone balance in soybean, the present study was carried out during 2008-2009 at research site of azad university of karaj branch as factorial based on randomized complete block design with two factors and four replications. treatments were all combination of arbuscular mycorrhizal fungi species...

the research aims at studying the effects of mycorrhizal fungi (glomus fasciculatum, g. mosseae and mixed composition) on growth, photosynthesis and nutrient absorption of ziziphus spina-christi in mehran greenhouse, ilam province. the result showed that colonization rate in mixed treatment was more than pure treatment of g. fasciculatum and g. mosseae. also, root fresh weight, stomatal conduct...

BACKGROUND The complex network of direct and indirect relationships determines not only the species abundances but also the community characteristics such as diversity and stability. In this context, seed predation is a direct interaction that affects the reproductive success of the plant. For Acrocomia aculeata, the seed predation by Pachymerus cardo and Speciomerus revoili in post-dispersal m...

Soil receptivity to arbuscular mycorrhizal (AM) fungi tests the capacity of a soil to favour the mycorrhizal development after inoculation. Thus, receptivity is a key criterion to assess whether the introduction of non-indigenous AM fungi will successfully improve plant growth. Two experiments were set up to investigate the receptivity of a moderately acidic wheat-growing soil of the Argentinea...

Araucaria angustifolia (Bert.) O. Ktze., a native forest tree from Brazil, is under extinction risk. This tree depends on arbuscular mycorrhizal fungi for growth and development, especially in tropical low-P soils but, despite being a conifer, Araucaria does not form ectomycorrhiza, but only the arbuscular endomycorrhiza. This study aimed at surveying data on the spore density and root coloniza...

Soil is a reservoir for Aspergillus flavus and A. parasiticus, fungi that commonly colonize peanut seeds and produce carcinogenic aflatoxins. Densities of these fungi in soil vary greatly among fields and may influence the severity of peanut infection. This study examined the relationship between soil density of Aspergillus species and the incidence of peanut seed colonization under laboratory ...

In recent years, the use of soil microbial potential including arbuscular mycorrhizal fungi is widely considered to enhance the better growth and nutrition of plants. This research was conducted in order to study the impact of mycorrhizal fungi on the increase of yarrow production and the plant establishment affected by the symbiotic ...

Pathogenic and mutualistic microbes actively suppress plant defense by secreting effector proteins to manipulate the host responses for their own benefit. Current knowledge about fungal effectors has been mainly derived from biotrophic and hemibiotrophic plant pathogenic fungi and oomycetes with restricted host range. We studied colonization strategies of the root endophytic basidiomycete Pirif...

Organic farmers across Saskatchewan face soil phosphorus (P) shortages. Due to the restriction on inputs in organic systems, farmers rely on crop rotation and naturally-occurring arbuscular mycorrhizal fungi (AMF) for plant P supply. Crop rotation is important for disease, pest, and weed management. Crops that are not colonized by AMF (non-mycorrhizal) can decrease colonization of a following c...
