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 study demonstrated that abundance and composition of arbuscular mycorrhizal fungi in roots and soils of Ipomopsis aggregata are influenced by ungulate herbivory and water availability. Results showed that herbivory led to an increase in spore production, diversity of AMF taxa in roots, and a shift in AMF species composition in rhizosphere soils, with the impact varying based on water availability. These findings contribute to a better understanding of mycorrhizal function under changing climates.

Summary: Arbuscular mycorrhizal fungi (AMF) form a symbiotic alliance with land plants and exchange nutrients. Studying the genomes of AMF provides clues to understand their biology, evolution, and ecology. The dynamics of nuclei, the abundance of transposable elements, and the epigenome landscape contribute to intraspecific variability, which is essential for AMF's adaptability to various hosts and environmental changes. Recent research has also revealed new insights into plant-fungus communication and the role of phosphate transport, deepening our understanding of this ancient symbiosis.

Summary: This study identifies the main factors influencing the tripartite association between legumes, arbuscular mycorrhiza fungi (AMF), and nitrogen-fixing rhizobia. It finds that different AMF strains can enhance nodulation in legumes, especially under heat-stress conditions. The impact of rhizobia on mycorrhizal colonization depends on the specific AMF strain. Additionally, phosphorus enhances nodulation while nitrogen does not affect mycorrhizal colonization.

Summary: This study investigated the distribution of arbuscular mycorrhizal fungal (AMF) community in pepper roots and rhizosphere soil along a precipitation gradient in China, finding precipitation and soil pH to be the main drivers of AMF community structuring. The study also revealed that different AMF families showed varying relative abundance along the precipitation gradient, with habitat filtering playing a key role in shaping the AMF communities. Additionally, rice cultivation in rotation systems and high soil-available phosphorus content may limit the maintenance of AMF diversity in subtropical and tropical croplands.

Summary: Through three controlled experiments, researchers found that the environmental settings of habitat connectance and quality can influence the diversity and predictability of AMF fungi in plant roots. Although manipulating environmental parameters did not affect the diversity of AMF assemblages, mixing habitats and varying connectance did make the assemblages less predictable.

Summary: This study characterized the symbiotic phenotypes of four Medicago truncatula mutants and identified two genes, RAM1 and KIN3, involved in mycorrhization. The results showed that RAM1 acts upstream of KIN3 and that KIN3 is involved in suppressing plant defenses and promoting root colonization. KIN3 also plays an essential role in the symbiotic response to soil nitrogen levels.

Summary: Mycorrhiza is a symbiotic association between plant roots and fungi, with arbuscular mycorrhizal fungi (AMF) being the most prominent type. AMF rely on host plants for photosynthates and provide benefits in return. They help improve host plants' tolerance against various biotic stresses through mechanisms like nutrient competition and rhizosphere alteration. The effectiveness of AM associations in conferring biotic stress tolerance is influenced by various biotic and abiotic factors.

Summary: The dominant Archaeal communities in arable soils are Nitrososphaeria, which includes all known ammonia-oxidizing archaea. This study used phylogenetic information and machine learning to identify the drivers of Nitrososphaeria along a large European gradient, with key predictors being mean annual temperature, C:N ratio, and pH. Specializations to soil pH were found in the Nitrososphaeria phylogeny, highlighting the importance of fine phylogenetic scale in studying their ecology.

Summary: A 4-year field experiment in a semiarid shrubland found that short-term climate manipulation had little impact on the composition and diversity of arbuscular mycorrhizal fungal communities, but changes in temperature and rainfall led to a significant decrease in some AMF families. These results provide insights into the conservation of soil biodiversity in dryland ecosystems facing climate change.

Summary: Dead wood quantity and quality play a crucial role in forest biodiversity by influencing wood-inhabiting fungal communities. The diversity of fungal communities varies across tree species and stem compartments, with bark exhibiting higher fungal diversity than wood. Different fungal communities are associated with gymnosperms and angiosperms, and distinctive fungi are found in the inner wood compared to other compartments. Stem traits, including accessibility, stem chemistry, and physical defense, have significant effects on fungal community structure in decaying stems.

Summary: This study conducted in Switzerland compared the effect of three cropping systems on soil quality. The results showed that no-till and organic farming systems had improved soil properties compared to conventionally tilled fields, particularly in the surface layer. Clay content, microbial carbon, and mycorrhizal PFLA biomarkers were identified as the major drivers of soil organic carbon concentration and carbon accumulation in the large macroaggregate fraction. The study highlights the potential of organic agriculture and no-till practices in improving soil carbon and aggregation properties.

Summary: By combining field data and greenhouse experiments, the authors demonstrate the impact of agricultural management practices, such as fungicide applications, on the provision of phosphorus to plants by arbuscular mycorrhizal fungi (AMF) in the soil. Their research suggests that AMF in grassland soils are more efficient in acquiring and transferring phosphorus to plants compared to AMF in cropland soils, which are affected by fungicide use. These findings highlight the importance of land-use intensity and fungicide application in determining the functioning and natural nutrient uptake capacity of AMF in agroecosystems.

Summary: This study investigated the response of a pea-barley mixture, an important fodder intercrop, to drought under four different cropping systems. The results showed that pea plants always took up more water from shallower depths, while barley plants took up less. The water uptake patterns of both species were not affected by the cropping systems. These findings suggest that cropping systems may not be as effective as previously thought in adapting to drought.
