Summary: This study manipulated AMF communities in grapevine rootstock and found that specific AMF communities had differential effects on grapevine rootstock growth and nutrient uptake. The presence of its own AMF community generally improved the performance of a rootstock. AMF spore diversity and the relative abundance of certain species played important roles in competition and growth outcomes.

Summary: This article reviews the role of arbuscular mycorrhizal fungi (AMF) in improving crop drought tolerance, highlighting their effects on water supply and the biophysical mechanisms involved. Using a soil-plant hydraulic model, the authors demonstrate how AMF can enhance water transport in the soil and extend root length to mitigate the impact of soil drying on plant water potential. The synthesis of evidence and simulations suggest that AMF symbiosis postpones the onset of stress by regulating transpiration rates and leaf water potentials during drought, thus promoting crop survival under limited water availability. The article also calls for future research to integrate soil and root hydraulic dynamics in order to better understand the role of AMF in plant-water relations under changing climate conditions.

Summary: Inoculation of kenaf with AMF can enhance its tolerance to Cd, reduce Cd transport to aboveground plant tissues, and improve plant growth. AMF can also increase cell wall polysaccharide content, which helps bind Cd in the cell wall. Additionally, AMF can reduce the biological effectiveness of Cd by increasing soil pH and organic matter content.

Summary: Arbuscular mycorrhizal fungi (AMF) promote the establishment and growth of grassland plant species when grown in isolation, but form networks that negatively impact biomass of establishing forb and grass seedlings within grassland communities. The study found that severing ingrowing mycorrhizal fungal hyphae resulted in reduced AMF colonization and increased seedling biomass, regardless of various factors.

Summary: The study found that warming significantly altered the AMF community structure, with higher AMF richness under the simulated warming chamber, but only at the elevation of 3,500 m. Warming did not affect other AMF alpha diversity indices. Glomus and Acaulospora were the dominant AMF genera in control and warming treatments at different elevations.

Summary: Auxins are a class of plant hormones that play roles in the establishment and maintenance of arbuscular mycorrhizal symbiosis (AMS). In this study, it was found that the transcription factors ARFs and AUX/IAAs in the auxin signaling pathway co-regulate the transcription of auxin response genes, highlighting their importance in the early stage of AMS. Additionally, SlARF6 was found to negatively regulate AMF colonization, while SlIAA23 promoted AMS and phosphorus uptake by interacting with SlARF6. Furthermore, SlARF6 and SlIAA23 played opposing roles in strigolactone synthesis and accumulation in AMF-colonized tomato roots.

Summary: This study found that phosphorus and water play crucial roles in farmland ecosystems. Field experiments were conducted to investigate the effects of different water and phosphorus concentrations on arbuscular mycorrhizal fungi (AMF). Results showed that under suitable drought treatment, AMF became more abundant and beneficial for plant growth. AMF abundance also varied with phosphorus treatments, with higher abundance in low-phosphorus treatments, which is more favorable for plant growth.

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: The study found that arbuscular mycorrhizal fungi (AMF) can improve plant tolerance to low-temperature stress by regulating proline accumulation. Nitric oxide (NO) plays an important signaling role in proline metabolism. The level of environmental nitrogen (N) affects AMF colonization and its contribution to plant resistance under low-temperature conditions.

Summary: Remediation of Hg-contaminated soil using mycorrhizal technology is environmentally friendly. However, the lack of research on the composition of arbuscular mycorrhizal fungi (AMF) in Hg-polluted soil hinders its biotechnological applications. This study sequenced the AMF communities in Hg mining areas and found that Glomeraceae was the dominant family. AMF diversity was influenced by soil Hg content, water content, and other soil properties.

Summary: The study introduced a semi-automated, high-throughput SIP pipeline to support well-replicated experiments in soil microhabitats, showcasing how this approach can improve operational efficiency and reproducibility in studying actively growing microbes within AMF hyphosphere. This method generated a series of metagenome-assembled genomes (MAGs) from C-13-labeled AMF hyphosphere DNA, revealing insights into key processes involved in nutrient cycling within the hyphosphere.

Summary: The AMF community in poplar roots showed higher diversity and species composition in autumn than in spring. The formation of the symbiotic mycorrhizal system and the AMF community were influenced by season, host age, host species, and soil environmental factors. Differences in the communities could be explained by soil pH, total nitrogen, total phosphorus, total potassium, available potassium, and glomalin content. The change in the mycorrhizal symbiotic system was closely related to the growth and development of poplar trees.

Summary: This study evaluated the impact of relay intercropping of durum wheat and lentils on soil mycorrhizal fungi. The results showed that relay intercropping increased lentil grain yield and durum wheat grain protein concentration, and enhanced soil mycorrhizal activity. However, the effect on mycorrhizal root colonization varied. The changes in AMF species diversity and community structure were mainly influenced by crop species and year.

Summary: The study found that endophyte infection significantly increased colonization rates and rhizosphere soil biomass of AMF, impacting the composition of AMF communities. The effects of endophyte on AMF biomass in rhizosphere soil were primarily mediated by soil physicochemical properties such as total carbon, total nitrogen, and pH.
