Summary: The results of this study showed that the use of AMF significantly improved the root growth and morphology of peanut plants in both saline-alkali and normal soils, leading to increased pod biomass and yield. AMF also enhanced the physical and chemical properties of the peanut rhizosphere soil, especially in saline-alkali soil, and increased the activities of soil enzymes. Overall, this study provides a theoretical basis and technical support for using AMF in peanut production in saline-alkali soil.

Summary: This study demonstrates that plant genotypes may be adapted to the water availability of their local environment, involving associations with local soil biota; under extreme soil drying conditions, dry site ecotypes tend to perform better, and sympatric soil inoculum helps enhance associations between plants and AM fungi. The findings suggest that co-adaptation between plants and their associated AM fungi can help alleviate drought stress, as shown by the positive correlation between AM fungal structures and plant growth, particularly in sympatric pairs.

Summary: The study investigated the differences in AMF communities in the roots of sago palm trees in mineral soil and shallow peat soil in Sarawak, Malaysia. It found that the lower abundance and diversity of AMF in shallow peat soil may be caused by abiotic factors, including soil physicochemical properties. Additionally, certain Glomus and Acaulospora species in shallow peat soil showed strong tolerance to acidity and high soil moisture content.

Summary: Symbiotic associations with different arbuscular mycorrhizal fungi (AMF), namely Rhizoglomus custos (Custos), Rhizoglomus sp. (Aznalcollar), and Rhizophagus irregularis (Intraradices), were studied to investigate their effectiveness in reducing heavy metal stress in wheat grown in contaminated soils. The indigenous Aznalcollar fungus showed higher levels of metal accumulation, while the non-indigenous Custos and Intraradices fungi exhibited depletion of some metals. Both Custos and Intraradices fungi demonstrated greater bioaccumulation capacity in the less-contaminated soil. The enzymatic activity and antioxidant systems of the plants increased in all AMF treatments, indicating improved plant protection in HM-contaminated environments.

Summary: Roots are an essential component of soils globally and play a significant role in soil formation and function. They contribute to soil formation by altering rocks and soil minerals, provide carbon inputs with long residence times, and facilitate mutualistic symbioses and nutrient uptake. The functionality of soils, including food and fuel supply, nutrient cycling, water filtration, and disease suppression, all depend on the activities of plant roots.

Summary: Fertilization is an important measure in agriculture, with nitrogen being a crucial nutrient for plants. The interaction between plants, rhizosphere microorganisms, and nitrogen is a key area of research in both life sciences and agricultural microorganism utilization.

Summary: The microbial structure of the root zone is complex, especially in plants with rhizosheaths, and understanding the rhizosheath may play a crucial role in sustainable agriculture. However, there is no definitive method for separating the rhizosheath. This study aimed to explore rhizosheath isolation methods and analyze the diversity characteristics of microorganisms in the rhizosphere. The results showed differences in bacterial and fungal community structures among the root epidermis, endophytic bacteria, rhizosheath, and rhizosphere soil.

Summary: This study conducted an ingrowth core experiment in three vegetation types in the Mu Us Desert, northern China, revealing the importance of fine roots and mycorrhizal fungi in shaping soil nutrient composition and microbiome, especially in desert ecosystems. AMF-related inputs were found to be crucial determinants of soil multifunctionality and microbial community diversity, particularly in shrub and grass communities.

Summary: This study focuses on the interactions of symbionts in the rhizosphere of leguminous plants, specifically the effects of AM fungi on the population levels and relationships of different trophic groups of soil microorganisms. The experimental model used different genotypes of garden peas inoculated with AM fungi to observe their influence over two plant growth cycles. Results indicate that AM fungi have a dominant effect on micromycetes and actinomycetes densities, with possible antagonistic effects, while stimulating ammonifying, phosphate-solubilizing, and diazotrophic Azotobacter bacteria, indicating mutualistic relationships. Additionally, genotype was found to play a decisive role in the populations of mineral NH4+-N immobilizing bacteria and Rhizobium bacteria.

Summary: This study used quantified imaging techniques to explore the effects of plant fine roots and arbuscular mycorrhizal fungi (AMF) on soil macropores. It found that soil macropore properties improved significantly with vegetation succession, and the effects of plant fine roots and AMF were mediated through direct and indirect mechanisms.

Summary: This study found that plants' shade-tolerance influences their root arbuscular mycorrhizal (AM) fungal communities, with shade-intolerant plants showing lower AM fungal beta-diversity in shaded conditions due to preferential carbon allocation to specific AM fungi when plant-assimilated carbon available to fungi was limited. Favourable environmental conditions, such as optimal light availability, reduce plants' selectivity for specific AM fungi and promote compatibility with a larger number of AM fungal taxa.

Summary: AMF infection enhances the growth of ephemeral plants, significantly influencing the carbon cycle and CH4 flux in desert ecosystems. AMF contributes up to 24% of R-e and only 15% of total CH4 flux, with non-AMF microorganisms being the main contributors to CH4 flux. Variations in R-e are strongly associated with soil organic carbon, soil available potassium concentrations, and soil temperature.

Summary: This study investigated the composition of native Arbuscular Mycorrhizal Fungi (AMF) species in two different soils and their impact on the development and stability of soil aggregates after inoculation with allochthonous AMF. The results showed that the native AMF influenced the activity of allochthonous AMF and there were differences in the stability of macro-sized aggregates between the two soils.
