Summary: This review summarizes the research findings on alkaloids produced by mushrooms in the last 20 years (2002-2022), including their isolation, structures, and biological activities, as well as their potential in drug and agrochemical development. The synthesis of some compounds and structure-activity relationship studies are also described.

Summary: The allocation of tree biomass to leaves, roots, and wood has implications for carbon residence time and storage in ecosystems. This study found that the type of mycorrhizal association, along with climate and leaf habit, significantly influenced biomass allocation. Trees associated with arbuscular mycorrhizal (AM) fungi allocated more biomass to root tissue compared to trees associated with ectomycorrhizal (ECM) fungi. Considering mycorrhizal associations could improve our understanding of ecosystem carbon storage.

Summary: Siderophores are small molecular iron chelators involved in cellular processes in fungi. This study discovered and identified five amphiphilic coprogen siderophores, including three new natural products, from Trichoderma hypoxylon. Genetic deletions of dfcA and dfcB genes confirmed their involvement in coprogen biosynthesis and their role in combating pathogenic fungi.

Summary: Bacteria and fungi have evolved sophisticated systems to acquire the biologically inaccessible trace element iron through high affinity Fe(III)-specific binding compounds called siderophores. A unique subset of siderophores with photoactive iron complexes has been recognized in the last 20 years, which disrupts the traditional understanding of forming and transporting stable Fe(III) complexes.

Summary: This study investigated the removal efficiency of lead-contaminated wastewater by ecological floating-beds (EFBs) inoculated with different arbuscular mycorrhizal fungi (AMF) inocula. The results showed that AMF could promote host plant growth and enhance the Pb removal efficiency of the EFBs.

Summary: Iron acquisition is crucial for the virulence of Aspergillus fumigatus. AtrR, in cooperation with SrbA, is involved in the transcriptional activation of iron uptake, in addition to SreA. Functional sequences resembling binding motifs for SrbA, SreA, and AtrR were identified in the promoter of the iron permease-encoding gene, ftrA. This study emphasizes the direct involvement of SrbA, AtrR, and SreA in iron regulation and highlights the coordination of iron homeostasis with biosynthesis of ergosterol and heme as well as adaptation to hypoxia.

Summary: This study explores the role of silicate ore pretreatment and the biogenic siderophores produced by Bacillus thuringiensis in the bioleaching process of gold and other elements. The results show that an effective pretreatment method involves ball milling and ozonation, and the highest leachability is achieved through a two-step conditioning approach. The study also finds that commercial siderophores and amino acids can facilitate the leaching of gold and elements, offering a promising method for the efficient recovery of these valuable elements.

Summary: Using 454 amplicon pyrosequencing, this study investigated the spatial variations in the community of orchid mycorrhizal fungi (OMF) and endophytic fungi in the roots of four co-occurring Habenaria species. The results showed that different fungi communities contribute to the spatial separation of these four species.

Summary: First principles predict that there is a relationship between plant and mycorrhizal fungal diversity, but this relationship is inconsistent on larger scales, likely due to different relationships between different mycorrhizal fungal guilds and plant diversity, scale dependency, and lack of coordinated sampling efforts. Understanding the coupling between plant and mycorrhizal fungal diversity across scales is important for predicting the ecosystem consequences of species gains and losses.

Summary: Meroterpenoids, derived from terpenoids, are widely distributed in plants, animals, and fungi, with complex structures and diverse bioactivities. A systematic review on meroterpenoids from higher and lower fungi has been lacking since the first summary in 2009. This review classifies and summarizes the natural meroterpenoids from fungi, highlighting their unique structures and promising bioactivities.

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: Arbuscular mycorrhizal fungi form a vital symbiotic relationship with plants to enhance plant-iron homeostasis and improve nutrient uptake. This symbiosis facilitates iron solubility by altering root architecture and producing iron-binding root exudates. Additionally, interactions with soil bacteria, including siderophore-producing bacteria, further enhance the benefits of mycorrhizal symbiosis. However, molecular mechanisms involved in these intricate networks are still largely unknown.
