Summary: Inoculation of arbuscular mycorrhizal fungi (AMF) and yeast significantly affected the growth and antioxidant response of Oenothera picensis plants in Cu mine tailings amended with compost. The co-inoculation of AMF and yeast promoted shoot and root biomass, influenced antioxidant activity, and reduced total phenols in the roots. Furthermore, yeast inoculation decreased non-enzymatic antioxidant activity and both AMF and yeast inoculation enhanced the production of photosynthetic pigments.

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: 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: The interaction between poisonous weeds and neighboring plants is complex. Arbuscular mycorrhizal fungi (AMF) and plant pathogenic fungi (PPF) play important roles in the interspecific relationships of plants. This study found that the interaction between Leymus chinensis and Stellera chamaejasme significantly inhibited aboveground growth but promoted underground growth. As the proportion of S. chamaejasme increased, the nitrogen content and pH in the rhizosphere soil of L. chinensis decreased, while the relative abundance of AMF in L. chinensis rhizosphere soil increased. The study also revealed the regulatory role of AMF and PPF in the interactive effects of both plants.

Summary: This study found that arbuscular mycorrhizal fungi (AMF) can effectively remove copper (Cu) and tetracycline (TC) pollutants in constructed wetlands (CWs). They enhance the growth of Canna indica L. and increase the removal rates of Cu and TC, while also altering the microbial community structures.

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: This research investigates the combined effects of Epichloe endophytes and arbuscular mycorrhizal fungi (AMFs) on tall fescue under saline-alkali stress. The findings demonstrate that endophyte infection enhances tall fescue's resistance to saline-alkali stress by increasing biomass and nutrient uptake, as well as altering ion concentration. The beneficial effect of endophytes is further enhanced by the presence of beneficial AMF, but reduced by the presence of detrimental AMF.

Summary: The allocation of tree biomass to leaves, roots, and wood has implications for carbon residence time and storage in ecosystems. This study found that the type of mycorrhizal association, along with climate and leaf habit, significantly influenced biomass allocation. Trees associated with arbuscular mycorrhizal (AM) fungi allocated more biomass to root tissue compared to trees associated with ectomycorrhizal (ECM) fungi. Considering mycorrhizal associations could improve our understanding of ecosystem carbon storage.

Summary: Arbuscular mycorrhizal fungi (AMF) play important roles in soil and plant productivity through their nutritional and non-nutritional functionalities. They maintain soil structure, change nutrient acquisition, alleviate stress, and interact with other microorganisms and plants, all of which contribute to plant growth and productivity.

Summary: Plant mycorrhizal associations impact the accumulation and persistence of soil organic matter, which can affect how ecosystems respond to global changes. The co-occurrence of trees and shrubs with different mycorrhizal associations can influence soil organic matter pools, but more research is needed to understand these effects.

Summary: Efficient management of root-associated microbiomes is crucial for improving crop yield and reducing environmental footprint. Various plant symbionts, such as arbuscular mycorrhizal fungi, have entered large-scale applications in agriculture. Research on the combination of arbuscular mycorrhizal fungi with other beneficial microbes should be further conducted to maximize their potential in crop production.

Summary: Soil micronutrient availability, particularly zinc (Zn), is a limiting factor in crop yield. Arbuscular mycorrhizal (AM) fungi facilitate nutrient uptake in host plants through the mycorrhizal pathway. In this study, RNA-seq analysis revealed that the putative Zn transporter gene, MtZIP14, was up-regulated in Medicago truncatula roots during colonization by Rhizophagus irregularis. Loss-of-function mutant plants lacking MtZIP14 showed reduced shoot biomass when grown under low Zn concentration and colonized by AM fungi, implicating a role for MtZIP14 in plant Zn nutrition and AM colonization.

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: Selenium is an essential trace element for humans, and AMF inoculation and selenium fertilizer application have a promoting effect on selenium uptake in soybean. Fertilization with selenite and inoculation with different AMF strains affect the speciation, biomass and accumulation of selenium in soybean. The combined use of AMF inoculation and selenium fertilizer increases the bioavailable selenium in soil and promotes the total selenium concentration and organic selenium accumulation in soybean. These results suggest that AMF inoculation combined with selenium fertilizer can be a promising strategy for selenium biofortification in soybean.
