The study of arbuscular mycorrhizal (AM) fungi and the AM symbiosis formed with host plant roots is complicated by biotrophic hypogeous nature mycobionts involved. To overcome this, several attempts have been made during last three decades to obtain this in vitro. use root-organ cultures has proved particularly successful. In review, we describe method which (transformed nontransformed) obtained, together choice species, inoculation techniques, culture media. We also outline potential...
Abstract Background A conventional tenet of classical genetics is that progeny inherit half their genome from each parent in sexual reproduction instead the complete transferred to daughter during asexual reproduction. The transmission hereditary characteristics parents offspring therefore predictable, although several exceptions are known. Heredity microorganisms, however, can be very complex, and even unknown as case for coenocytic organisms such Arbuscular Mycorrhizal Fungi (AMF). This...

In order to improve the use inoculants, 12 fungi (AMF) inoculants were evaluated in a two-step experiment under greenhouse conditions using maize. First, propagated trap pot culture sterilized sand evaluate their potential for maize (Zea may L.) root colonization as compared with an indigenous soil...
Acer saccharum Marsh. (sugar maple) is one of only few arbuscular mycorrhizal trees to form extensive stands in northern temperate biomes. Recent maple decline could result from altered intensity and quality root colonization by associated mycobionts or possible shifts symbiotic fungal community composition following environmental stresses. In this study the effects on fungi soil acidification, several proposed causal stresses underlying forest decline, remedial liming were investigated...
Arbuscular mycorrhizae (AM) are symbiotic associations, formed between plants and soil fungi that play an essential role in plant growth, protection, quality. The AM expand their filaments roots. This filamentous network promote bi-directional nutrient movement where nutrients water move to the photosynthates flow fungal network. ubiquitous can form symbiosis with most terrestrial including major crops, cereals, vegetables, horticultural plants. In agriculture, several factors, such as host...
SUMMARY Osmium tetroxide was used to sterilize the surface of roots Vaccinium angustifolium and V. corymbosum in order isolate mycorrhizal fungi. Three isolates sterile mycelium, all similar cultural appearance, were obtained from proved capable forming ericoid mycorrhizas under aseptic conditions. also formed conidiophores identified as Oidiodendron griseum Robak; they
Summary Rhizophagus irregularis is the model species for arbuscular mycorrhizal fungi (AMF) research and most widely propagated commercial plant biostimulants. Using asymbiotic symbiotic cultivation systems initiated from single spores, advanced microscopy, Sanger sequencing of glomalin gene, PacBio partial 45S rRNA we show that four strains R. produce spores two distinct morphotypes, one corresponding to morphotype described in protologue other having phenotype R . fasciculatus The spore...

SUMMARY Oidiodendron griseum, O. cerealis, rhodogenum, tenuissimum and truncatum were tested for their endophytic ability on axenic seedlings of Vaccinium angustifolium grown a synthetic nutrient medium. rhodogenum cerealis produced typical intracellular hyphal coils characteristic the ericoid infection. For these three species, level infection reached 9 to 21 % root cells after 60 d incubation. truncation did not infect roots but latter species stunted development secondary reduced growth seedlings.
Summary Arbuscular mycorrhizal fungi ( AMF ) are important plant symbionts that have long been considered evolutionary anomalies because of their apparent long‐term lack sexuality, but recent explorations available DNA sequence challenged this notion by revealing the presence homologues fungal mating type – high‐mobility group MATA ‐ HMG and core meiotic genes in these organisms. To obtain more insights into sexual potential , s were sought transcriptome three isolates, functional...
Glomus cubense ( Glomeraceae, Glomeromycetes ) was isolated from a lagoon vegetation area on clay soil deposition environment in the vicinity of San José de las Lajas, Cuba. The species description is based spore morphological parameters vivo pot cultures and molecular analyses. new characterized by its small, generally irregular shape, 20-48 × (24–)54-72 μm hyaline to faintly yellow spores that have 2-layered wall arise clusters. Phylogenetic analyses rDNA ITS region H+ATPase place into...
Plant adaptation to hyperosmotic environments is generally associated with reduced growth and ultimately yield loss, making farming difficult. The potential of mycorrhizal symbioses alleviate salt stress has been documented benefits plant revealed be specific dependent both cultivars fungal strains. A factorial greenhouse experiment was performed determine the effects three arbuscular fungi (AMF) species (Funneliformis caledonius, F. mosseae Rhizophagus irregularis) on ‘day-neutral’...
Ribosomal nuclear genes are routinely utilized in the molecular identification of fungi. The variation multiple copies these within each Glomeromycota strain and species reduces their usefulness for characterization arbuscular mycorrhizal To explore potential tools Glomus species, a multi-gene analysis approach was undertaken. Three protein-encoding were tested, namely elogation factor 1-α (765 bp), V-H + -ATPase VHA5 (1468 F0F1-ATPase β-subunit (621 bp). latter is newly reported...
To investigate the influence of arbuscular mycorrhizal fungi (AMF) on biomass and root morphology, a greenhouse experiment was conducted using three elite strawberry ( Fragaria × ananassa Duch.) cultivars (‘Kent’, ‘Jewel’, ‘Saint-Pierre’). They were subjected to NaCl levels (0, 30, 60 mmol/L) inoculated noninoculated (control) with AMF Glomus irregulare . The presence significantly changed morphology increased root-length percentages medium (0.5 mm < diameter φ ≤ 1.5 mm) coarse (φ >...
Arbuscular mycorrhizal fungi (AMF) are a group of soil microorganisms that establish symbioses with the vast majority land plants. To date, generation AMF coding information has been limited to model genera grow well axenically; Rhizoglomus and Gigaspora. Meanwhile, data on functional gene repertoire most families is non-existent. Here, we provide primary large-scale transcriptome from eight poorly studied species (Acaulospora morrowiae, Diversispora versiforme, Scutellospora calospora,...
