Francis Martin and colleagues report genome sequences for 18 species of mycorrhizal fungi a phylogenomic analysis including 32 other fungal genomes. The study identifies cell wall-degradation genes lost in all true ectomycorrhizal and, using gene expression data, finds candidate the establishment symbiosis. To elucidate genetic bases lifestyle evolution, we sequenced new genomes, 13 (ECM), orchid (ORM) ericoid (ERM) species, five saprotrophs, which analyzed along with Ectomycorrhizal have...
Summary Some soil fungi in the Leotiomycetes form ericoid mycorrhizal ( ERM ) symbioses with Ericaceae. In harsh habitats which they occur, plant survival relies on nutrient mobilization from organic matter SOM by their fungal partners. The characterization of genetic machinery underpinning both symbiotic lifestyle and degradation is needed to understand symbiosis functioning evolution, its impact carbon (C) turnover. We sequenced genomes Meliniomyces bicolor , M. variabilis Oidiodendron...
Abstract Mutualistic plant-associated fungi are recognized as important drivers in plant evolution, diversity, and health. The discovery that mycoviruses can take part play roles symbiotic tripartite interactions has prompted us to study the viromes associated with a collection of ericoid orchid mycorrhizal (ERM ORM, respectively) fungi. Our study, based on high-throughput sequencing transcriptomes (RNAseq) from fungal isolates grown axenic cultures, revealed both ERM ORM presence new...
Abstract During arbuscular mycorrhizal (AM) colonization, a focal accumulation of organelles occurs in root epidermal cells, prior to fungal penetration, beneath adhering hyphopodia. This is followed by the appearance prepenetration apparatus (PPA), transcellular column cytoplasm connected nucleus and rich cytoskeleton secretory endomembranes. appears be responsible for construction an apoplastic compartment that confines fungus within cell lumen. To identify AM-specific elements PPA...
Abstract Some heavy metal tolerant fungal isolates capable of forming ericoid mycorrhiza can also confer increased tolerance to the host plant. One these isolates, Oidiodendron maius Zn, has been characterized and a few molecular mechanisms underlying its phenotype have identified. Here, we investigate genomic divergences between available genome O. Zn genomes sensitive , with aim identifying genes or intergenic regions possibly involved in display tolerance. The resequenced 8 10 were mapped...
Plants harbor in their external surfaces and internal tissues a highly diverse finely structured microbial assembly, the microbiota. Each plant compartment usually represents unique ecological niche hosting distinct community differentiation, which may mirror functions of specialized microbiota, has been mainly investigated for bacteria. Far less is known fungal components plant-associated Here, we applied metabarcoding approach to describe assemblages different organs Vaccinium myrtillus...
The genome sequences of mycorrhizal fungi will provide new opportunities for studying the biology and evolution underlying this symbiotic lifestyle. generation null mutants at wild-type loci is one best methods gene-function assignment in post-genomic era. To our knowledge, superoxide dismutase 1 (SOD1)-null ericoid fungus Oidiodendron maius first example a gene-targeted disruption via homologous recombination fungus. OmSOD1 by Agrobacterium-mediated transformation resulted presence...
A sterile mycelium PS IV, an ascomycete capable of establishing ericoid mycorrhizas, was used to investigate how zinc ions affect the cellular mechanisms fungal growth. Asignificant reduction biomass observed in presence millimolar concentrations; this mirrored conspicuous changes hyphal morphology which led apical swellings and increased branching subapical parts. Specific probes for fluorescence electron microscopy localised chitin, main cell wall polysaccharide, on inner part septa...
Although adaptive metal tolerance may arise in fungal populations polluted soils, the mechanisms underlying metal-specific are poorly understood. Comparative proteomics is a powerful tool to identify variation protein profiles caused by changing environmental conditions, and was used investigate accumulation tolerant isolate of ericoid mycorrhizal fungus Oidiodendron maius exposed zinc cadmium. Two-dimensional gel electrophoresis shotgun followed mass spectrometry lead identification common...
Asbestos minerals are commonly found in serpentine rocks and because of the hazard to human health, research has recently focused on possible detoxification strategies. Some fungal species that inhabit sites (two disused chrysotile asbestos mines Western Alps) have been isolated characterized order obtain data their biodiversity bioweathering abilities fibres. The three dominant (Verticillium leptobactrum, Paecilomyces lilacinus Aspergillus fumigatus) proved be able actively remove iron from...
Plant growth and development can be influenced by mutualistic non-mutualistic microorganisms. We investigated the ability of ericoid endomycorrhizal fungus Oidiodendron maius to influence non-host plant Arabidopsis thaliana. Different experimental setups (non-compartmented compartmented co-culture plates) were used investigate both soluble volatile fungal molecules on phenotype. O. promoted A. thaliana in all setups. In addition, a peculiar clumped root phenotype, characterized shortening...
Possible agents for the decontamination and bioremediation of asbestos-polluted soils: selected soil fungi modify bind asbestos fibers. The picture shows a single fiber in intimate contact with hyphae Fusarium oxysporum (the bar upper left corresponds to 20 μm). produce metal chelators which extract iron ions from Supporting information this article is available on WWW under http://www.wiley-vch.de/contents/jc_2002/2003/z19820_s.pdf or author.

The sequence encoding a superoxide dismutase (SOD) was isolated from the cDNA library of zinc-tolerant strain ericoid mycorrhizal fungus Oidiodendron maius, grown under zinc-stress conditions. Sequence homology to other SODs strongly suggests that it is copper- and zinc-containing SOD. Functional complementation assays showed gene confers increased tolerance zinc copper stress Cu,ZnSOD-defective yeast mutant. Monitoring transcript protein levels following OmSOD1 expression controlled at...
Mutualistic and pathogenic plant-colonizing fungi use effector molecules to manipulate the host cell metabolism allow plant tissue invasion. Some small secreted proteins (SSPs) have been identified as fungal effectors in both ectomycorrhizal arbuscular mycorrhizal fungi, but it is currently unknown whether SSPs also play a role other associations. Ericoid mycorrhiza specific endomycorrhizal type that involves symbiotic mostly belonging Leotiomycetes (Ascomycetes) plants family Ericaceae....
The success of Ericaceae in stressful habitats enriched heavy metals has been ascribed to the distinctive abilities their mycorrhizal fungal partners withstand metal stress and enhance tolerance host plant. Whereas extensively investigated some ericoid (ERM) fungi, molecular cellular mechanisms that extend plant are currently unknown. Here, we show a reduced Cd content Cd-exposed roots Vaccinium myrtillus colonised by tolerant isolate fungus Oidiodendron maius, as compared non-mycorrhizal...
In a previous study several strains of soil fungi were reported to remove iron in vitro from crocidolite asbestos, process that was envisaged as possible bioremediation route for asbestos-polluted soils. Here, we get some new insight into the chemical basis fiber/fungi interaction by comparing action most active fungal strain Fusarium oxysporum on three kind asbestos fibers--chrysotile, amosite, and crocidolite--and surface-modified crocidolite. None fibers examined significantly inhibited...
