Arbuscular mycorrhizal (AM) symbioses are mutualistic associations between soil fungi and most vascular plants. The symbiosis significantly affects the host physiology in terms of nutrition and stress resistance. Despite the lack of host range specificity of the interaction, functional diversity between AM fungal species exists. The interaction is finely regulated according to plant and fungal ...
This experiment aims at establishing the ability of the endomycorrhizal fungus Glomus intraradices to suppress the plant pathogen Pythium ultimum in cherry tomato. A study published in Canadian Journal of Plant Pathology in 1994 showed that Glomus intraradices suppresses Pythium ultimum in Tagetes patula (french marigold) (St-Arnaud, Fortin, Caron, & Hamel, 1994). Pythium ultimum and other Pyth...
The aim of this work was to evaluate the inoculation effect of two new endophytic diazotrophic bacteria and the interaction between arbuscular mycorrhizal fungi (AMF) and these bacteria on wheat plants. The experiment was carried out in a greenhouse with the two strains of diazotrophic bacteria, IAC11HT (Achromobacter insolitus) and IAC12HT (Zoogloea ramigera), and two AMF (Glomus sp. and Acaul...
The study evaluated the response of alfalfa (Medicago sativa L) to arbuscular mycorrhizal fungi (AM) species Glomus intraradices and Sinorhizobium meliloti, strain 1021 regarding the dry biomass accumulation, mycorrhizal fungi colonization, nodulation and nitrogen fixation activity. Alfalfa plants were grown in a glasshouse until the flowering stage (58 days), in 4 kg plastic pots using leached...
A greenhouse experiment was conducted in order to evaluate the efficiency of seven Arbuscular Mycorrhizal Fungi (AMF) namely, Acaulospora deligata, Glomus aggregatum, G feugianum, G fasciculatum, G rubiforme, Gigaspora margarita, and Scutellospora heterogama collected from the rhizosphere soils of Wedilia chinensis (Osbeck) Merril. They were evaluated on the same host for improvement of phytoch...
Arbuscular mycorrhiza (AM) symbioses contribute to global carbon cycles as plant hosts divert up to 20% of photosynthate to the obligate biotrophic fungi. Previous studies suggested carbohydrates as the only form of carbon transferred to the fungi. However, de novo fatty acid (FA) synthesis has not been observed in AM fungi in absence of the plant. In a forward genetic approach, we identified t...
Sweet majoram (Majorana hortensis L.) is one of the native Iranian medicinal plants, which due to its aromatic secondary metabolites is used in traditional medicine. In production of medicinal plants, application of organic inputs has especial role in sustainable agriculture. Organic inputs, such as manures and compost, other than providing the necessary elements for plant growth, could improve...
BACKGROUND AND AIMS Plant parasitism and arbuscular mycorrhizal (AM) associations have many parallels and share a number of regulatory pathways. Despite a rapid increase in investigations addressing the roles of AM fungi in regulating interactions between parasitic plants and their hosts, few studies have tested the effect of AM fungi on the initiation and differentiation of haustoria, the para...
Citrus fruits are susceptible to salinity. In the present study, the reaction of trifoliate sour orange (Poncirus trifoliata L.) to the salinity stress at the presence of Arbuscular Mycorrhizal Fungi (AMF) was investigated. Forty-day-old seedlings were inoculated with three species of AMF in combinations including Glomus mosseae + Glomus intraradices, Glomus mosseae + Glomus hoi, Glomus intrar...
