    Abstract Importance: The integration of metabolomics-based approaches into the discovery pipeline has enabled improved mining and prioritization of prolific secondary metabolite producers such as endophytic fungi. However, relying on automated untargeted analysis tools might lead to misestimation of the chemical complexity harbored in these organisms. Our study emphasizes the importance of isolation and structure elucidation of the respective metabolites in addition to deep metabolome analysis for the correct interpretation of untargeted metabolomics approaches such as molecular networking. Additionally, it encourages the further exploration of endophytic fungi from traditional medicinal plants for the discovery of natural products.

  3. Article ; Online: Diversity and distribution of tropical ectomycorrhizal fungi

    Abstract The tropics were long considered to have few ectomycorrhizal fungi, presumably due to a paucity of ectomycorrhizal host plants relative to higher-latitude ecosystems. However, an increase in research in tropical regions over the past 30 years has greatly expanded knowledge about the occurrence of tropical ectomycorrhizal fungi. To assess their broad biogeographic and diversity patterns, we conducted a comprehensive review and quantitative data analysis of 49 studies with 80 individual data sets along with additional data from GlobalFungi to elucidate tropical diversity patterns and biogeography of ectomycorrhizal fungi across the four main tropical regions: the Afrotropics, the Neotropics, Southeast Asia, and Oceania. Generalized linear models were used to explore biotic and abiotic influences on the relative abundance of the 10 most frequently occurring lineages. We also reviewed the available literature and synthesized current knowledge about responses of fungi to anthropogenic disturbances, and their conservation status and threats. We found that /russula-lactarius and /tomentella-thelephora were the most abundant lineages in the Afrotropics, the Neotropics, and Southeast Asia, whereas /cortinarius was the most abundant lineage in Oceania, and that /russula-lactarius, /inocybe, and /tomentella-thelephora were the most species-rich lineages across all of the tropical regions. Based on these analyses, we highlight knowledge gaps for each tropical region. Increased sampling of tropical regions, collaborative efforts, and use of molecular methodologies are needed for a more comprehensive view of the ecology and diversity of tropical ectomycorrhizal fungi.

    Abstract BACKGROUND AND AIMS: Amazonia comprises a mosaic of ecosystems that harbor high biodiversity. Knowledge about fungal diversity and ecology in this region remains very limited. Here, we examine soil fungal communities in forests of the Colombian Amazonia and their relationship to important edaphic variables. METHODS: Fungal communities were studied in terra-firme forests dominated by arbuscular mycorrhizal (AM) trees, terra-firme forests with the ectomycorrhizal (EcM) tree Pseudomonotes tropenbosii (Dipterocarpaceae), and white sand forests (WSF) with the EcM host plant genera Dicymbe and Aldina (Fabaceae). Fungal community composition was determined through 454-pyrosequencing of the ITS2 region of ribosomal DNA. We established the impact of the type of forest and edaphic parameters in structuring the fungal communities. RESULTS: We found a high diversity of fungi with 2,507 OTUs occurring in the soil samples studied. Carbon content and pH were the main edaphic factors contributing to structure the fungal community across all forests. Fungal community composition differs among terra-firme plots and WSF, while it was similar among AM and EcM-dominated areas in terra-firme. Our results revealed an important EcM fungal diversity in terra-firme AM-forests, where some EcM plants such as the ones in the genera Coccoloba and Neea occur scattered within an AM-matrix. CONCLUSIONS: This is a first approximation to understand the ecology of soil fungal communities in forests of the Colombian Amazonia. We found that fungal soil communities have a spatial variation related to forest type (terra-firme and WSF), soil pH, and soil carbon content. Due to the strong correlation between vegetation and soil fertility in Amazonia, it is difficult to understand the effects of those factors to the fungal communities.

    Abstract Diacanthodes (Polyporales, Basidiomycota) is a fungal genus with stipitate basidiomata and a combination of ornamented and dextrinoid basidiospores that is unique among the poroid fungi. Although some hypotheses based on morphological features speculated about the phylogenetic relationships of the taxon, they have never been tested based on molecular data. We performed molecular phylogenetic analyses including specimens of Diacanthodes from the Neotropics and Africa using the internal transcribed spacers (ITS1-5.8S-ITS2 = ITS) and the D1–D2 domains of the 28S gene of the nuclear rDNA regions, as well as the translation elongation factor 1-alpha (TEF-1α) protein-coding gene. Our study revealed Diacanthodes as a member of the ‘core polyporoid’ clade within the Polyporales. Two new species from South America: Diacanthodes cerebriporoides and D. neotropicalis, a new combination D. coffeae from Africa and notes on the other Diacanthodes species are presented. Basidiospore morphology in Diacanthodes and related genera is discussed in the phylogenetic context.

    Abstract Bioactive secondary metabolite production from endophytic fungi has gained a recurring research focus in recent decades as these microorganisms represent an unexplored biological niche for their diverse biotechnological potential. Despite this focus, studies involving tropical endophytes remain scarce, particularly those isolated from medicinal plants of these ecosystems. In addition, the state of the art of the pharmaceutical industry has experienced stagnation in the past 30years, which has pushed pathogenic infections to get one step ahead, resulting in the development of resistance to existing treatments. Here, five fungal endophytes were isolated from the medicinal plant
