Summary: Inoculation of arbuscular mycorrhizal fungi (AMF) and yeast significantly affected the growth and antioxidant response of Oenothera picensis plants in Cu mine tailings amended with compost. The co-inoculation of AMF and yeast promoted shoot and root biomass, influenced antioxidant activity, and reduced total phenols in the roots. Furthermore, yeast inoculation decreased non-enzymatic antioxidant activity and both AMF and yeast inoculation enhanced the production of photosynthetic pigments.

Summary: This study evaluated the effects of an AM fungus (Rhizophagus irregularis) and potassium concentration on Lycium barbarum. The results showed that inoculation of R. irregularis and application of potassium increased the dry weight, potassium and phosphorus contents of L. barbarum, and increased the colonization rate and arbuscule abundance of R. irregularis. In addition, the expression of LbKAT3 and AQP genes in L. barbarum was upregulated. Overall, LbKAT3 may assist in mycorrhizal potassium uptake, and overexpression of LbKAT3 may promote potassium, phosphorus, and water transport from the AM fungus to tobacco.

Summary: Coal mine sites with sandy soils often have low nutrient and high heavy metal concentrations, making reclamation for agricultural uses challenging. The combined use of arbuscular mycorrhizal fungi and nano humus can significantly improve soil chemical properties, reduce soil heavy metal concentrations, and promote plant growth. This combined application has the greatest impact on the root and shoot biomass of alfalfa and shows positive effects on barley when combined with arbuscular mycorrhizal fungi, nano humus, and fertilizer.

Summary: This study found that AMF can promote root colonization of maize in the presence of Cr(VI), though it does not significantly increase the uptake of Pi at lower Cr(VI) concentrations. Additionally, the presence of 1 mg L-1 Cr(VI) stimulates non-mycorrhizal plants to absorb more Pi and Cr(VI) compared to mycorrhizal plants.

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 aimed to explore the global distribution pattern and key predictors of arbuscular mycorrhizal fungi (AMF) diversity and abundance. It was found that cold climate zones had lower AMF diversity. Grassland ecosystems tended to have higher AMF diversity and abundance. Soil available phosphorus (P) and latitude were identified as the most important predictors of AMF diversity. Soil available P and soil pH were the main predictors for the global distribution of AMF abundance. The findings advance our understanding of the mechanisms underlying the distribution patterns of mycorrhizal fungal diversity and abundance at the global scale.

Summary: Phosphorus is an essential macronutrient for plant growth, but it is often limited in soil. This study investigated the effects of phosphorus limitation on leaf pigments and enzymes in Zea mays, and how these effects changed throughout the growing season. The results showed that phosphorus limitation strongly influenced plant growth and leaf-level measurements. However, phosphorus limitation decreased over time, and most of the fertilization effects disappeared after 2 months of planting. These findings suggest that the symbiosis with arbuscular mycorrhizal fungi plays a crucial role in explaining the vanishing phosphorus stress.

Summary: In this study, shading was found to significantly decrease soluble sugar concentration in the phloem of mycorrhizal maize, leading to a decrease in root biomass under shading conditions. Additionally, mycorrhizal P response decreased with increasing P supply levels. The findings suggest a tight linkage between carbon allocation and P uptake systems in maintaining mycorrhizal functioning in agroecosystems.

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: This article introduces a conceptual model of the cross-scale effect of heavy metals (HMs) on biogeochemical services by services providing units (SPUs) and proposes a method for applying the model. The objectives are to identify research clusters related to the effects of HMs on ecosystem services (ES), biodiversity, and resilience, map scientific fields necessary for implementation of the model, describe the complexity of cause-effect chains, and suggest approaches for implementing the model in contaminated socio-ecological systems. The analysis shows that current research focuses on microbial communities and functional traits, with less emphasis on larger-scale issues. The evaluation indicates the importance of this model in contaminated socio-ecological systems.
