Summary: Silver nanoparticles (AgNPs) are harmful to plants, but arbuscular mycorrhizal fungi (AMF) can alleviate their toxicity. Concentration is the main factor influencing the phytotoxicity of AgNPs. Different antioxidant enzymes have different tolerances to AgNPs, and the growth configuration and Ag accumulation and translocation in plants are less affected by AgNPs. AMF inoculation improves plant antioxidant capability and biomass growth, and regulates the root:shoot ratio to cope with AgNP stress.

Summary: Plants form mutualistic nutrient-acquiring symbioses with microbes like arbuscular mycorrhizal fungi, and employ a negative feedback loop called autoregulation of mycorrhizae (AOM) to limit the formation of these symbioses. Specific genes like FAB, FIN, and SlCLV2 have been identified as playing roles in negatively regulating arbuscular mycorrhizal formation in tomato. Furthermore, external nutrients such as phosphate and nitrate can strongly suppress arbuscular mycorrhizal formation, with FAB and FIN being required for nitrate suppression but not for phosphate suppression. This suggests a deep homology in the symbiotic role of these genes, potentially forming a common symbiotic toolkit for beneficial plant-microbe interactions.

Summary: The study found that different types of microplastics have varying effects on maize growth, with high doses of PLA potentially causing strong phytotoxicity and reducing biomass. ZnO nanoparticles had minimal effects on plant growth, but led to zinc accumulation in plants and an increase in soil pH. Both microplastics and ZnO nanoparticles influenced the composition and diversity of AM fungal communities.

Summary: Mitoviruses in the Mitoviridae family are mitochondria-replicating RNA viruses found in fungi, plants, and invertebrates. Distinct mitoviruses called large duamitoviruses were discovered in glomeromycotinian fungi, with an unusually large RdRp encoding and a unique N-terminal motif. These viruses are found globally in soil ecosystems and form the most basal clade of the Mitoviridae family. We propose that large duamitoviruses are the most ancestral lineage of the Mitoviridae exclusively maintained in glomeromycotinian fungi.

Summary: Increased nitrogen availability in temperate forests alters carbon and nitrogen cycling. Trees associated with ectomycorrhizal fungi reduce carbon allocation to roots and mycorrhizal fungi more than those associated with arbuscular mycorrhizal fungi in response to long-term nitrogen fertilization. Nitrogen-induced decoupling of roots and microbes in ectomycorrhizal trees is evidenced by greater declines in extracellular enzyme activities.

Summary: This study investigated the effects of arbuscular mycorrhizal symbiosis on miRNA expression in switchgrass. Through miRNA analysis and degradome sequencing, it was found that both upland and lowland genotypes, as well as upland-lowland hybrids, responded to mycorrhizal symbiosis and targets of miRNAs involved in symbiosis were identified. Copper miRNA downregulation was common amongst the different genotypes, and superoxide dismutases and laccases were among the identified targets.

Summary: The old Zn-Pb-contaminated tailings in southern Poland are colonized by metal-tolerant Anthyllis vulneraria L. plants, which form symbiotic associations with nitrogen-fixing rhizobia and phosphorus-acquiring arbuscular mycorrhizal fungi. The mycorrhizal status and diversity of the fungi in these legumes have been poorly studied. Metal ions accumulate mainly in the nodules and fungal structures in the roots, rather than the plant cell walls. The mycorrhization parameters for the plants in the tailings were significantly higher than those in the non-metallicolous site, indicating a potential role of the unique fungal symbionts in enhancing plant tolerance to heavy metal stress.

Summary: Trait-based approaches in ecology are powerful tools for understanding how organisms interact with their environment. They are particularly effective in disturbance and community ecology contexts, such as studying how disturbances like prescribed fire and bison grazing impact mutualistic interactions between AM fungi and plant hosts. This study examined the effects of disturbance on AM fungal spore community composition and mutualisms, and found that selection for specific spore traits and changes in community composition were indicators of fire and grazing effects. These findings highlight the importance of trait-based approaches in clarifying belowground responses to disturbance and understanding organism-environment interactions.

Summary: Ongoing climate change and long-term overgrazing are the main causes of global grassland degradation. Phosphorus (P) is typically a limiting nutrient in degraded grassland soils and its dynamics are important for the responses of carbon (C) feedback to grazing. However, the effects of different grazing levels on multiple phosphorus processes and their impact on soil organic carbon (SOC) are still not well understood.

Summary: A strain of Cr(VI)-resistant bacterium, identified as Bacillus cereus ZY-2009, showed high tolerance to Cr(VI) and effectively removed Cr(VI) through enzyme-mediated bioreduction. Co-existing Fe3+ and Cu2+ enhanced Cr(VI) removal, while Cd2+ inhibited it. This strain has potential for bioremediation of Cr(VI)-containing wastewater with Fe3+ and Cu2+ as stimulators.

Summary: Through a 10-month soil incubation experiment, we found that both nitrogen deposition and microplastics have significant effects on soil multifunctionality. Nitrogen deposition increased carbon cycling processes but inhibited nitrogen fixation, nitrification, and denitrification. Microplastics also stimulated these processes, especially in soils with nitrogen deposition.

Summary: The use of arbuscular mycorrhizal fungi (AMF) is important for enhancing phytoremediation of heavy metals, but their role under molybdenum (Mo) stress is unclear. This study investigated the effects of AMF inoculation on Mo uptake, transport, and physiological growth of maize plants under different Mo levels. The results showed that AMF inoculation increased biomass and induced different growth allocation strategies in response to Mo stress. It also enhanced the uptake of nutrients, improved photosynthetic leaf pigment content, and reduced Mo transport, indicating their potential for the bioremediation of Mo-polluted soil.

Summary: The effects of micro(nano)plastics (MNPs) on soil nutrient cycling, particularly carbon (C), nitrogen (N), and phosphorus (P), are reviewed. MNPs can alter soil nutrient cycling by affecting soil nutrient availability, enzyme activities, microbial communities, and ecological functions. The effects of MNPs depend on their characteristics, chemical additives, soil conditions, and biota. Multi-scale experiments using environmentally relevant MNPs are needed to further understand the impacts of MNPs on soil nutrients.

Summary: Microplastics (MPs) are widely distributed in agroecosystems and pose a potential threat to soil-plant systems. The effects of high-density polyethylene (HDPE), polystyrene (PS), and polylactic acid (PLA) on peanuts and soil N-fixing bacterial communities were explored. MPs did not have phytotoxic effects on plant biomass, and PS and PLA even increased plant height. All MPs changed soil nitrogen contents and the activities of urease and FDAse. PLA especially had pronounced effects on plant nitrogen content and soil N-fixing bacterial community structure. The findings suggest that biodegradable MPs may have more profound consequences for nitrogen biogeochemical cycling than traditional MPs.

Summary: The effect of different fermentation methods on heavy metal bioaccessibilities in wheat flour is uncertain. This study assessed the gastric and gastrointestinal heavy metal bioaccessibility in wheat flour products, and found that cadmium, zinc, and manganese bioaccessibility was higher in the gastric phase than in the gastrointestinal phase, while copper showed the opposite pattern. Lead bioaccessibility in the gastrointestinal phase was significantly greater than in the gastric phase for the QD sample, and only the control had higher bioaccessibility in the gastrointestinal phase than in the gastric phase for the NX sample. The over-fermented treatments showed higher bioaccessibilities of cadmium, copper, zinc, and manganese in the gastric phase compared to the control and normally fermented treatment. However, in the gastrointestinal phase, only the over-fermented dough with Na2CO3 showed higher manganese bioaccessibility compared to the control for the NX sample. The enhanced degradation of heavy metal-phytate following over-fermentation may contribute to the increased bioaccessibility of heavy metals.
