Summary: Biostimulant application is an effective and sustainable way to supplement crop nutrition, reduce excessive fertilization, and protect plants from environmental stresses. Biostimulants, both microbial and non-microbial, provide beneficial properties to plants, promote crop yield and quality, and enhance soil fertility. Among microbial biostimulants, arbuscular mycorrhizal fungi (AMF) play a crucial role in sustainable agriculture by improving nutrient availability, uptake, and assimilation, increasing plant stress tolerance, and reducing soil erosion. Further research is needed to better understand the effectiveness of different biostimulants in sustainable agriculture.

Summary: This study demonstrates that native AMF inoculation can significantly increase tomato yield and lycopene concentration. The inoculation of single species Claroideoglomus claroideum may lead to better plant performance due to its high production of extraradical mycelium.

Summary: Nitrous oxide (N2O) is a potent greenhouse gas, and agricultural soils are a major anthropogenic source. Crop residues act as hotspots of N2O production. Arbuscular mycorrhizal fungi (AMF) can proliferate in organic patches, utilize released N, and potentially mitigate N2O emissions. However, the effect of AMF on N2O emissions in degraded residue patches and the microbial mechanism remain uncertain.

Summary: This study investigated the interactions between arbuscular mycorrhizal fungi (AMF), foliar endophytes, and insects on Impatiens glandulifera. The results showed that AMF reduced plant biomass, while foliar endophytes increased aphid numbers. There were more interactions between AMF and endophytes than between endophytes themselves.

Summary: Arbuscular mycorrhizal fungi (AMF) form symbiotic relationships with land-dwelling plants, improving growth and productivity, especially during abiotic stress. AMF enhances nutrient acquisition and plant tolerance to abiotic stress through nutrient exchange at the arbuscular mycorrhizal interface. AMF also affects plants' antioxidant defense systems, osmotic adjustment, and hormone regulation, promoting plant performance in abiotic stress conditions. More research is needed to understand the molecular mechanisms and responses of AMF-plant interactions to abiotic stresses.

Summary: Plants can be colonized by fungi with both harmful and beneficial effects. One way the fungi colonize is by secreting effector proteins that change the plant's physiology to suit the fungus. Arbuscular mycorrhizal fungi (AMF), the oldest plant symbionts, may benefit from using effectors. Recent research has focused on understanding the function, evolution, and diversification of AMF effectors through genome analysis and transcriptomic studies. However, only a small fraction of the predicted effector proteins have been characterized, limiting our understanding of how they manipulate their host plants and which plant proteins they interact with.

Summary: Soil conditioners and beneficial microorganisms are important for increasing the sustainability of agro-systems. This study found that biochar and zeolites increased the soil cation exchange capacity, which can benefit the system in the long-term. However, using commercial mycorrhizal fungi in a mature olive orchard showed little benefit.

Summary: The study investigated the impact of two fungicides on the performance of arbuscular mycorrhizal fungi (AMF) and found that low doses of the fungicides enhanced root colonization by AMF, while high doses suppressed their performance. The fungicides generated biphasic response curves in irradiated soil, indicating a hormetic effect on AMF.

Summary: Cadmium (Cd) levels in food crops can be increased through management activities and geogenic factors. Arbuscular mycorrhizal fungi (AMF) play a significant role in reducing Cd accumulation in plants. AMF have various mechanisms to reduce shoot Cd accumulation, including immobilizing Cd in fungal structures and increasing root Zn uptake.

Summary: The study showed that mycorrhizal fungi have a positive effect on the root architecture traits of fig trees, with a cultivar-dependent pattern and a preference for figs with coarse root architecture. Different root architecture models were induced by the fungi in different cultivars, suggesting diverse root strategies for exploiting soil resources.

Summary: Microplastics have diverse effects on soil and plant growth, altering soil structure and microbial activity, which in turn affects the abundance and activity of arbuscular mycorrhizal fungi. The impacts of microplastics may also change how plants respond to other global change factors, highlighting the need for further research on their overall impact on ecosystems.

Summary: Increasing crop diversity can enrich the AMF communities in agricultural soils, counteracting the negative effects of agricultural intensification. Soil properties determine the composition of AMF communities, while root colonization by AMF is influenced by crop host rather than farm management practices.

Summary: Two independent field experiments were conducted to assess the effects of plant growth promoting rhizobacteria (PGPR), arbuscular mycorrhizal fungi (AMF), and compost on lettuce growth, yield, and soil properties. The results showed that the application of biofertilizers and biostimulants significantly increased the growth and yield of lettuce compared to the control, as well as improved soil properties.

Summary: The fungal community in canola was influenced by crop diversification, unlike the bacterial community. No core microbiota was found in canola roots, but three core fungi were identified in the rhizosphere, one core mycobiota in the bulk soil, and one core bacterium shared by the rhizosphere and bulk soil. Inter-kingdom network analysis revealed two bacterial and one fungal hub taxa in the canola rhizosphere, and one bacterial and two fungal hub taxa in the bulk soil, with Bradyrhizobium sp. and Mortierella sp. being particularly influential. This study is the first to use inter-kingdom network analysis to identify interaction hot spots in canola microbial communities.

Summary: Interventions with commercial inoculants have the potential to reduce the environmental footprint of agriculture, but their indiscriminate deployment has raised questions on the unintended consequences of microbial invasion. This article examines the present framework used to define arbuscular mycorrhizal fungi (AMF) invasion and offers perspectives on the steps needed to avoid negative impacts. It suggests strategies to reduce overdependence on introduced inoculants and recommends policies and regulations to monitor inoculant value chains.

Summary: The effects of symbiotic associations between microorganisms, plants, and insects have been extensively studied. However, little is known about the impact on natural enemies. This study investigated the effects of symbiotic relationships between an arbuscular mycorrhizal fungus, a nitrogen-fixing bacterium, and soybean on two natural enemies of soybean aphids. The results showed that the symbiotic relationship had only a slight impact on one of the natural enemies, but had no significant effect on the other or on the predator.

Summary: Oomycetes play a critical role in soil microbial communities and have significant impacts on agriculture. However, they are understudied compared to bacteria and fungi, and our understanding of their biodiversity and community structure in soil over time is limited. This study investigated the influence of soil history on Oomycetes communities in the roots and rhizosphere of different Brassicaceae crops. The results showed that soil history and chemistry had a significant impact on the structure and biodiversity of Oomycetes communities, highlighting the importance of agricultural practices in shaping future microbial communities.

Summary: African microbiomes have been underestimated in the past, with an overemphasis on research in the Global North. Africa possesses significant genetic diversity in its ecosystems, humans, and animals. In this Comment, we address the lack of available microbiome datasets from Africa and suggest measures to promote microbiome research in the region.
