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.

The concept of a root economics space (RES) is increasingly adopted to explore trait variation and belowground resource-acquisition strategies. Much progress has been made on interactions morphology mycorrhizal symbioses. However, exudation, with significant carbon (C) cost (c. 5-21% total photosynthetically fixed C) enhance resource acquisition, remains missing link in this RES. Here, we argue that incorporating exudation into the structure RES key holistic understanding soil nutrient acquisition. We highlight different functional roles exudates phosphorus (P) nitrogen (N) Thereafter, synthesize emerging evidence illustrates how interacts symbioses at level species individual plant contrasting patterns evolved P-impoverished vs N-limited environments. Finally, propose new conceptual framework, integrating three groups traits better capture complexity Such deeper integrated dynamic morphology, will provide valuable insights mechanisms underlying coexistence for sustainable managed systems.

Plant roots associate with diverse microbes (including bacteria, fungi, archaea, protists, and viruses) collectively called the root-associated microbiome. Among them, mycorrhizal fungi colonize host improve their access to nutrients, usually phosphorus nitrogen. In exchange, plants deliver photosynthetic carbon colonizing fungi. This nutrient exchange affects key soil processes, cycle, plant health therefore has a strong influence on microbe ecosystems. The framework of regulation between arbuscular recently been established. local systemic symbiosis by status autoregulation mycorrhizae are strategies which maintain stabilizing free-market symbiosis. A better understanding synergistic effects mycorrhizosphere microorganisms is an essential precondition for use as biofertilizers bioprotectors sustainable agriculture forestry management.

The symbiotic interaction between plants and arbuscular mycorrhizal (AM) fungi is often perceived as beneficial for both partners, though a large ecological literature highlights the context dependency of this interaction. Changes in abiotic variables, such nutrient availability, can drive along mutualism-parasitism continuum with variable outcomes plant growth fitness. However, AM benefit more ways than improved phosphorus nutrition growth. For example, promote biotic stress tolerance even when considered parasitic from provision perspective. Other being obligate biotrophs, very little known about benefits gain plants. In review, we utilize molecular biology approaches to expand our understanding plant-AM fungal across disciplines.

Associations between soil minerals and microbially derived organic matter (often referred to as mineral-associated or MAOM) form a large pool of slowly cycling carbon (C). The rhizosphere, immediately adjacent roots, is thought control the spatial extent MAOM formation because it dominant entry point new C inputs soil. However, emphasis on rhizosphere implicitly assumes that microbial redistribution into bulk (non-rhizosphere) soils minimal. We question this assumption, arguing extensive fungal exploration rapid hyphal turnover, from common, encourages formation. First, we summarize published estimates length density turnover rates demonstrate are high throughout rhizosphere-bulk continuum. Second, colonization surfaces common dispersal mechanism for bacteria, argue allows non-random mineral by hyphae-associated taxa. Third, these bacterial communities their hosts determine chemical deposited colonized surfaces. Collectively, our analysis demonstrates omission hyphosphere conceptual models flow overlooks key mechanisms in soils. Moving forward, there clear need spatially explicit, quantitative research characterizing environmental drivers community composition across systems, important controls over rate chemistry minerals.

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.

Summary The extraradical hyphae of arbuscular mycorrhizal (AM) fungi are colonized by different bacteria in natural and agricultural systems, but the mechanisms which AM interact with hyphosphere soil microbiome influence organic phosphorus (P) mobilization remain unclear. We grew Medicago two‐compartment microcosms, inoculated Rhizophagus irregularis , or not, root compartment set up P treatments (without P, addition as KH 2 PO 4 nonsoluble phytate) hyphal compartment. studied processes turnover characterized functional profiles for metagenomic sequencing.

At species level, shift recruitment genome bin2.39 harbouring both gcd phoD genes bin2.97 gene, synergistically drove phytate soil. Our results suggest that recruits stimulated to enhance utilization phytate.
