Abstract Background Fungi and bacteria coexist in a wide variety of environments, their interactions are now recognized as the norm most agroecosystems. These microbial communities harbor keystone taxa, which facilitate connectivity between fungal bacterial communities, influencing composition functions. The roots plants associated with arbuscular mycorrhizal (AM) fungi, develop dense networks hyphae soil. surface these (called hyphosphere) is region where multiple can occur, e.g., exchanging or responding to each other’s metabolites. However, presence importance taxa AM hyphosphere remain largely unknown. Results Here, we used vitro pot cultivation systems fungi investigate whether certain were able shape growing potentially improved fitness host. Based on various soil leachates, synthetic found that under organic phosphorus (P) conditions, could selectively recruit enhanced P nutrition competed less P-mobilizing bacteria. Specifically, observed privileged interaction isolate Streptomyces sp.

Conclusions This work highlights multi-functionality fungal-bacteria bacterial-bacterial at hyphal fungi.

Significance Low availability of nitrogen (N), mainly nitrate in aerobic soils, is a primary limiting factor for crop production. Most terrestrial plants live symbiosis with arbuscular mycorrhizal (AM) fungi to increase nutrient uptake, including N, from soil. Research on the AM field has focused almost exclusively ammonium as form N transferred plants, and there been no direct evidence transfer thus far. Here, we report that rice could receive more than 40% its via pathway AM-specific transporter OsNPF4.5 accounted approximately 45% uptake. Our work suggests presence route uptake plants.

Abstract Nitrogen availability often restricts primary productivity in terrestrial ecosystems. Arbuscular mycorrhizal fungi are ubiquitous symbionts of plants and can improve plant nitrogen acquisition, but have a limited ability to access organic nitrogen. Although other soil biota mineralize into bioavailable forms, they may simultaneously compete for nitrogen, with unknown consequences nutrition. Here, we show that synergies between the fungus Rhizophagus irregularis microbial communities highly non-additive effect on acquisition by model grass Brachypodium distachyon . These multipartite result doubling acquire from matter tenfold increase compared non-mycorrhizal grown absence communities. This previously unquantified relationship contribute more than 70 Tg annually assimilated thereby playing critical role global nutrient cycling ecosystem function.

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

Summary Stress is ubiquitous and disrupts homeostasis, leading to damage, decreased fitness, even death. Like other organisms, mycorrhizal fungi evolved mechanisms for stress tolerance that allow them persist or thrive under environmental stress. Such can also protect their obligate plant partners, contributing health survival hostile conditions. Here we review the effects of response in fungi. We cover molecular cellular aspects how impacts individual physiology, growth, reproduction, interactions with along some tolerate address lead adaptation have cascading on population‐ community‐level diversity. argue fungal strongly shape not only but ecology evolution. conclude by pointing out knowledge gaps important future research directions required both fully understanding context addressing ongoing change.
