Abstract Background: Plant roots are usually colonized by various arbuscular mycorrhizal (AM) fungal species which vary in morphological, physiological and genetic traits and constitute the mycorrhizal nutrient uptake pathway (MP) in addition to roots. Simultaneously, the extraradical hyphae of each AM fungus is associated with a community of bacteria. However, whether the community structure and function of microbiome on the extraradical hyphae would differ between the AM fungal species are mostly unknown. Methods: In order to understand the community structure and the predicted functions of the microbiome associated with different AM fungal species, a split-root compartmented rhizobox culturing system, which allowed us to inoculate two AM fungal species separately in two root compartments was used. We inoculated two separate AM fungal species combinations, Funneliformis mosseae ( F.m ) and Gigaspora margarita ( G.m ), Rhizophagus intraradices ( R.i ) and G. margarita, on a single root system of cotton . The hyphal exudate fed active microbiome was measured by combining 13 C-DNA stable isotope probing with Miseq sequencing. Results: We found different AM fungal species, that were simultaneously colonizing on a single root system, hosted distinct active microbiomes from one another. Moreover, the predicted potential functions of the different microbiomes were distinct. Conclusion: We conclude that the arbuscular mycorrhizal fungi component of the system is responsible for the recruitment distinct microbiomes in the hyphosphere. The potential significance of the predicted functions of the microbiome ecosystem services is discussed.

AbstractExtraradical hyphae (ERH) of arbuscular mycorrhizal fungi (AMF) extend from plant roots into the soil environment and interact with soil microbial communities. Evidence of positive and negative interactions between AMF and soil bacteria point to functionally important ERH-associated communities. To characterize communities associated with ERH and test controls on their establishment and composition, we utilized an in-growth core system containing a live soil–sand mixture that allowed manual extraction of ERH for 16S rRNA gene amplicon profiling. Across experiments and soils, consistent enrichment of members of the Betaproteobacteriales, Myxococcales, Fibrobacterales, Cytophagales, Chloroflexales, and Cellvibrionales was observed on ERH samples, while variation among samples from different soils was observed primarily at lower taxonomic ranks. The ERH-associated community was conserved between two fungal species assayed, Glomus versiforme and Rhizophagus irregularis, though R. irregularis exerted a stronger selection and showed greater enrichment for taxa in the Alphaproteobacteria and Gammaproteobacteria. A distinct community established within 14 days of hyphal access to the soil, while temporal patterns of establishment and turnover varied between taxonomic groups. Identification of a conserved ERH-associated community is consistent with the concept of an AMF microbiome and can aid the characterization of facilitative and antagonistic interactions influencing the plant-fungal symbiosis.

The ontogenetic development and morphological properties of spores of two species of arbuscular mycorrhizal fungi (Glomeromycota) of the genus <em>Glomus</em>, <em>G. claroideum </em>and <em>G. spurcum</em>, are described and illustrated. Spores of the two species were not earlier found in Poland, and this paper is the first report of the occurrence of <em>G. spurcum </em>in Europe. In one-species pot cultures with <em>Plantago lanceolata </em>as the host plant, the mycorrhizae of <em>G. claroideum </em>consist of arbuscules, vesicles, as well as intra- and extraradical hyphae staining intensively with trypan blue. <em>Glomus spurcum </em>mycorrhizae were not recognized, because many attempts to establish one-species cultures of this fungus failed. Additionally, the distribution of both the fungi in the world is presented.
