The aim of the present work was to study colonization patterns in roots by different arbuscular mycorrhizal fungi developing from a mixed community soil. As cannot be distinguished with certainty planta on basis fungal structures, taxon‐discriminating molecular probes were developed. 5′ end large ribosomal subunit containing variable domains D1 and D2 amplified PCR Glomus mosseae (BEG12), G. intraradices (LPA8), Gigaspora rosea (BEG9) Scutellospora castanea (BEG1) using newly designed...
SUMMARY Arbuscular mycorrhizal (AM) fungi, which date from the Devonian era, must have dealt very early on with problems of plant defence, a tactic has enabled them to colonize roots most extant taxa. Conversely, plants forming arbuscular mycorrhiza exert some sort control over fungi during symbiotic interactions since mycelial proliferation within is confined cortical parenchyma tissue. Plants possess panoply defence mechanisms are triggered by microbial attack. Here we review present‐day...
We characterised the spatial structure of soil microbial communities in an unimproved grazed upland grassland Scottish Borders. A range chemical parameters, cultivable microbes, protozoa, nematodes, phospholipid fatty acid (PLFA) profiles, community-level physiological profiles (CLPP), intra-radical arbuscular mycorrhizal community structure, and eubacterial, actinomycete, pseudomonad ammonia-oxidiser 16S rRNA gene assessed by denaturing gradient gel electrophoresis (DGGE) were quantified....
The arbuscular mycorrhizal (AM) symbiosis belongs to the strategies plants have developed cope with adverse environmental conditions including contamination by heavy metals such as cadmium (Cd). In present work, we report on protective effect conferred AM model legume Medicago truncatula grown in presence of Cd, and 2-D-based proteomic approach further used compare proteomes M. roots either colonised or not fungus Glomus intraradices Cd-free Cd-contaminated substrates. results indicated that...
Two native Algerian mycorrhizal fungi (Glomus mosseae and Glomus intraradices) were tested for their effect on the growth of micropropagated olive tree (Olea europaea L.). The inoculation plantlets with G. was also compared chemical fertilization using osmocote. Specific molecular techniques then used to detect presence two fungi. Highly significant increases in evident inoculated plants uninoculated ones. For a slightly lower shoot growth, doubled root plantlets, that fertilized plants....
Arbuscular mycorrhizas represent the most widespread, and probably ancient, type of plant–fungus association in which large majority terrestrial plants must have evolved with compatibility systems towards fungal symbionts. Cellular interactions leading to reciprocal morphofunctional integration between symbionts during mycorrhiza establishment are complex. Some plant genes cellular events may be shared nodulation processes, but there is evidence molecular modifications specific arbuscular...
Endomycorrhizal fungi in Glomales have been classified as Zygomycetes, which generally chitin and chitosan cell wall components. Preliminary evidence suggested that the of at least one Glomus species possessed β (1 → 3) glucan polymers. A wider range taxa representative each four genera were analyzed for presence or absence glucans using indirect immunolabelling with commercial monoclonal polyclonal antibodies specific oligoglucosides. These structural polysaccharides present selected...
summary Previous studies showed that cell walls of endomycorrhizal fungi belonging to the Acaulosporaceae and Glomaceae contain β (1–3) glucan polymers as well chitin. Indirect immunolabelling with monoclonal polyclonal antibodies has been used investigate distribution these structural polysaccharides in Glomus mosseae (Nicol. & Gerd.) Gerd. Trappe Acaulospora laevis they interact pea tobacco roots, respectively. The (l‐3) glucans were detected external hyphae, hyphal coils intercellular...
• Premise of the study: Tuber aestivum , most common truffle in Europe, plays an important role commercial market. For first time, microsatellite primers were developed to investigate polymorphism within this species. Methods and Results: Using direct shotgun pyrosequencing, 15 polymorphic microsatellites identified out 7784 perfect present 534620 reads obtained. Tested on 75 samples, these highly polymorphic. The number alleles varied from four 15, expected heterozygosity ranged 0.266...
Summary Interactions between an arbuscular mycorrhizal fungus and pea cv. Frisson (myc+) or isogenic mycorrhiza-resistant mutant (myc−) were investigated by immunocytochemistry. Observations of the presence proteins polysaccharides accumulating in other symbioses (pectins) plant-pathogenic interactions (PR-b1 protein, ß-1,3-glucans) indicated a weak activation defence mechanisms during establishment symbiosis. In contrast, myc showed important reaction against fungus, suggesting that there...
