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: Aquatic plants in EFBs host diverse (229 OTUs) and abundant (348,799 sequences) AMF communities. Different plant species host different taxa of AMF. Cyperaceae, originally considered non-mycorrhizal, may actually belong to a variable mycorrhizal plant family. The composition of AMF communities in EFBs is closely linked to nutrient concentrations (nitrogen and phosphorus).

Summary: This study investigates the effects of spatial distribution of plant habitats on AMF root colonization and extraradical hyphae. The results show that habitats with high connectivity stimulate root colonization and induce denser functional root colonization. However, overdispersed habitats promote functional root colonization.

Summary: This article introduces a newly developed global AM fungi database that aims to reduce the limited understanding of AM fungal biogeography. The database contains millions of observations of AM fungal DNA sequences with geographical locations and additional metadata from various studies. It is an open source initiative that compiles the most comprehensive atlas of AM fungal distribution.

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: This study indicates that plant benefit in the symbiosis between plants and AMF is linked to fungal identity and phylogeny, showing that there are large differences in effectiveness of different AMF.

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 aimed to test the inhibitory action of mycorrhizal guava leaf extract and Meloidogyne enterolobii on Klebsiella pneumoniae carbapenemase strains. The leaf extract prepared using ethanol as a solvent showed positive potential in inhibiting multidrug-resistant bacterial strains. This plant-AMF-phytonematode interaction enhanced the inhibitory action of guava leaf ethanolic extract on multidrug-resistant bacterial strains.

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 study found that AMF abundance, richness, and diversity were higher in natural regeneration areas, with Acaulospora and Glomus being the most representative genera. The AMF community differed between study areas, but not between seasons, with soil attributes influencing this difference.

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: 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.
