Abstract Background Arbuscular mycorrhizal (AM) symbiosis has been referred to as the mother of all plant root symbioses it predated evolution roots. The AM research is a multidisciplinary field at intersection soil science, mycology, and botany. However, in recent decades nature properties soils, which develops functions, have received less attention than desired. Scope In this review we discuss number developments research. We particularly cover role acquisition phosphorus, nitrogen, heavy metals metalloids, well water by plants from soil; effects on nutritional stoichiometry carbon cycle; hyphosphere microbiome; so-called facultative plants; explanations for lack benefit; common networks; arbuscular ectomycorrhizal ecosystems. Conclusion reflect what previously described ‘dogmas’. conclude that these are fact generalisations supported multiple studies, while admitting there potentially geographical bias developed temperate boreal regions, other ecosystems might uncover greater diversity viable non-mycorrhizal strategies currently acknowledged. also note an increasing tendency overinterpret data, may lead stagnation some fields due experiments designed test mechanistic basis processes rather cumulating descriptive studies correlative evidences.

Summary Mycorrhizal symbioses between plants and fungi are vital for the soil structure, nutrient cycling, plant diversity, ecosystem sustainability. More than 250 000 species associated with mycorrhizal fungi. Recent advances in genomics related approaches have revolutionized our understanding of biology ecology associations. The genomes 250+ been released hundreds genes that play pivotal roles regulating symbiosis development metabolism characterized. rDNA metabarcoding metatranscriptomics provide novel insights into ecological cues driving communities functions expressed by these associations, linking to traits such as acquisition organic matter decomposition. Here, we review genomic studies revealed involved uptake development, discuss adaptations fundamental evolution lifestyles. We also evaluated services provided networks how hold promise sustainable agriculture forestry enhancing stress tolerance. Overall, unraveling intricate dynamics is paramount promoting sustainability addressing current pressing environmental concerns. This ends major frontiers further research.

Phosphorus (P) is an important nutrient for plants, and a lack of available P greatly limits plant growth development. Phosphate-solubilizing microorganisms (PSMs) significantly enhance the ability plants to absorb utilize P, which improving turnover yield. This article summarizes analyzes how PSMs promote absorption utilization nutrients by from four perspectives: types functions PSMs, phosphate-solubilizing mechanisms, main functional genes, impact complex inoculation on acquisition. reviews physiological molecular mechanisms phosphorus solubilization promotion with focus analyzing soil microbial communities its interaction root exudates. In order better understand their role in transformation provide prospects research promoting absorption. mainly activate insoluble through secretion organic acids, phosphatase production, mycorrhizal symbiosis, symbiosis indirectly activates via carbon exchange. can secrete acids produce phosphatase, plays crucial cycling, related genes are involved regulating P-solubilization ability. uptake great significance deeper understanding PSM-mediated utilization, efficiency agriculture.

Summary Arbuscular mycorrhizal (AM) fungi play an important role in soil organic matter (SOM) formation and stabilization. Previous studies have emphasized compounds produced by AM as persistent binding agents for aggregate SOM storage. This concept overlooks the multiple biogeochemical processes mediated fungal activities, which drive generation, reprocessing, reorganization, Here, we propose updated conceptual framework to facilitate a mechanistic understanding of dynamics. In this framework, four pathways fungi‐mediated dynamics are included: ‘Generating’, exudates biomass serve key sources chemodiversity; ‘Reprocessing’, hyphosphere microorganisms decomposition resynthesis; ‘Reorganizing’, mediate physical changes influence transport, redistribution, transformation, storage; ‘Stabilizing’, mineral weathering organo–mineral interactions Moreover, discuss at different scales, especially when translating results from small scales complex larger scales. We believe that working with can allow better dynamics, therefore facilitating development mycorrhiza‐based technologies toward health global change mitigation.

Abstract Background Plant microbiomes play crucial roles in nutrient cycling and plant growth, are shaped by a complex interplay between plants, microbes, the environment. The role of bacteria as mediators 400-million-year-old partnership majority land plants and, arbuscular mycorrhizal (AM) fungi is still poorly understood. Here, we test whether AM hyphae-associated influence success symbiosis. Results Using partitioned microcosms containing field soil, discovered that hyphae roots selectively assemble their own microbiome from surrounding soil. In two independent experiments, identified several bacterial genera, including Devosia , consistently enriched on hyphae. Subsequently, isolated 144 pure isolates mycorrhiza-rich sample extraradical sp. ZB163 root hyphal colonizer. We show this AM-associated bacterium synergistically acts with mycorrhiza to strongly promote nitrogen uptake, mycorrhization. Conclusions Our results highlight do not function isolation plant-mycorrhiza symbiont can recruit beneficial support

Linking the identity of wild microbes with their ecophysiological traits and environmental functions is a key ambition for microbial ecologists. Of many techniques that strive this goal, Stable-isotope probing-SIP-remains among most comprehensive studying whole communities in situ. In DNA-SIP, actively growing microorganisms take up an isotopically heavy substrate build heavier DNA, which can be partitioned by density into multiple fractions sequenced. However, SIP relatively low throughput requires significant hands-on labor. We designed tested semi-automated, high-throughput (HT-SIP) pipeline to support well-replicated, temporally resolved amplicon metagenomics experiments. applied soil microhabitat ecological importance-the hyphosphere zone surrounding arbuscular mycorrhizal fungal (AMF) hyphae.
