<p><strong>Background:</strong> The majority of terrestrial plants have evolved in symbiosis with beneficial microorganisms, which help them acquire minerals that are scarce soil, such as phosphorus and some cases nitrogen. Thus, the development use biofertilizers based on microorganisms is important for partial or total replacement chemical fertilizers. arbuscular mycorrhizal...

The effect of root exudates from non-mycorrhizal and mycorrhizal cucumber (Cucumis sativus L.) plants colonized by one of three arbuscular mycorrhizal fungi (Gigaspora rosea Nicolson & Schenck, Glomus intraradices Smith & Schenck, or Glomus mosseae (Nicolson & Gerdemann) Gerd. & Trappe) on hyphal growth of Gi. rosea and G. intraradices in axenic culture and on root colonization by G. mosseae in...

Plants inoculated with arbuscular mycorrhizal (AM) fungi utilize more soluble phosphorus from soil mineral phosphate than noninoculated plants. However, there is no information on the response of soil microflora to mineral phosphate weathering by AM fungi and, in particular, on the catabolic diversity of soil microbial communities. The AM fungus, Glomus intraradices was examined for (i) its eff...

Plant root exudates contain a range of low molecular weight metabolites that trigger many of the structural and physiological changes associated with the progression and establishment of mycorrhizal symbiosis. Here, the physiological response triggered by acetosyringone (AS) was studied in Glomus intraradices. Incubation of G. intraradices spores with AS resulted in an overall increase in hypha...

Maize (Zea mays) is the most widely grown crop species in the world and a classical model organism for plant research. The completion of a high-quality reference genome sequence and the advent of high-throughput sequencing have greatly empowered re-sequencing studies in maize. In this study, plants of maize inbred line B73 descended from two different sets of seed material grown for several gen...

We monitored the development of intraradical and extraradical mycelia of the arbuscular mycorrhizal (AM) fungi Scutellospora calospora and Glomus intraradices when colonizing Plantago lanceolata. The occurrence of arbuscules (branched hyphal structures) and vesicles (lipid storage organs) was compared with the amounts of signature fatty acids. The fatty acid 16:1omega5 was used as a signature f...

The presence of actinorhizas and arbuscular mycorrhizas may reduce plant stresses caused by adverse soil conditions. A greenhouse experiment was conducted using a sediment with a high pH, resulting from the disposal of waste originated at an acetylene and polyvinylchloride factory, in which Black alder (Alnus glutinosa) seedlings were inoculated either with Glomus intraradices BEG163 (originall...

An interaction study was performed with mycorrhizal plants of the grapevine rootstock Richter 110 (Vitis berlandieri Planch × Vitis rupestris Scheele) and the root pathogenic fungus Armillaria mellea (Vahl:Fr.) P. Kumm using an autotrophic in vitro culture system. Micropropagated plantlets were transferred to Petri plates with MSR medium lacking sugar and vitamins. Inocula of Glomus intraradice...

To explore the molecular mechanisms that prevail during the establishment of the arbuscular mycorrhiza symbiosis involving the genus Glomus, we transcriptionally analysed spores of Glomus intraradices BE3 during early hyphal growth. Among 458 transcripts initially identified as being expressed at presymbiotic stages, 20% of sequences had homology to previously characterized eukaryotic genes, 30...

قارچ‌های همزیست ریشه از جمله قارچ‌های میکوریزی قادر به تعدیل تنش‌های زنده و غیرزنده برای گیاه میزبان هستند و رشد، تغذیه و مقاومت گیاه به تنش شوری را تحت تأثیر قرار می‌دهند. شیرین‌بیان (Glycyrrhiza glabra) در آسیا برای بهره-برداری از ریشه آن برای مقاصد دارویی کشت و نیز به عنوان یک منبع علوفه برای دام استفاده می‌شود. به منظور بررسی تأثیر همزیستی با قارچ‌های اندوفیت بر برخی ویژگی‌های رشدی و فیزیول...
