Summary: In this study, the genetic diversity of mycobionts and cyanobionts in Peltigera lichens from high Andean steppes in southern Chile was assessed. Seven mycobiont species and eleven cyanobiont haplotypes, including a potential new Peltigera species, were discovered. These findings highlight the importance of high Andean steppe ecosystems as habitats for unexplored lichen species and contribute to our understanding of global Peltigera biodiversity.

Summary: Lichens are unique fungal symbioses that can form a new structure together with photosynthetic partners. The signals involved in the transition from a free-living state to a symbiotic state, called lichenization, and the maintenance of the symbiosis are not well understood. This study synthesizes existing knowledge into a concept of signaling involved in lichenization, including five stages: pre-contact, contact, envelopment, incorporation, and differentiation. Compounds such as fungal lectins and algal cyclic peptides may initiate early contact, while phytohormone signaling, antioxidant protection, and carbon exchange are important throughout all stages.

Summary: Lichens, a natural source of valuable compounds, have slow growth which makes them economically unfeasible. This study aimed to identify chemical constituents of the cultured mycobiont of Graphis sp. and isolated three eremophilane sesquiterpenes, including a new compound. The new compound showed moderate cytotoxic activity against the K562 cancer cell line.

Summary: This study examines the synthesis of melanin in lichen hyphae and reveals the presence of a melanized layer in the upper cortex of melanized thalli, as well as thicker hyphal cell walls in melanized thalli. Analysis indicates that eumelanin is synthesized in L. pulmonaria, with melanosomes transported to the cell surface and secreted into the cell walls during melanization.

Summary: Lichen symbioses are microecosystems that host a variety of organisms beyond the main lichen symbionts. Recent studies have shown that microalgal diversity in lichens is influenced by the growth stage, geographic area, and habitat type. The balance of different photobionts in lichens may not be as previously assumed.

Summary: This article presents the results of an experiment using transplanted mosses and lichens as biomonitors to optimize the detection of anthropogenic microfibers. The study found that the moss H. cupressiforme is a better indicator than the lichen P. furfuracea, especially when exposed without a covering net. The accumulation of microfibers was higher in moss compared to lichen, and naked transplants provided greater sensitivity.

Summary: The study found that endophyte richness and composition were consistent across different cultivation media types and largely robust to differences in storage period. Differences in endophyte richness, composition, and taxonomic diversity between culturing and NGS were significant, but both methods revealed host-structured communities. Comparing studies with variations in cultivation media or storage period can help estimate endophyte diversity at larger scales.

Summary: Understanding how tree diversity is structured in tropical forests by abiotic factors, climate, and biotic interactions, with seasonality playing a key role at landscape scales, researchers found that endophyte richness varies negatively with temperature seasonality. The structure and composition of endophyte communities reflect both temperature seasonality and climate, highlighting the vital role of climate-related factors in shaping the hyperdiversity of these symbionts that form the foundations of tropical forest biodiversity.

Summary: Six new 6-isopentylsphaeropsidones and a new hexadecanoic acid were isolated from a fungus inhabiting Douglas fir leaf litter. One of the compounds, strobiloscyphone F, contains a novel highly oxygenated tetracyclic ring system. These compounds showed cytotoxic and antimicrobial activities, and possible biosynthetic pathways were proposed by the researchers.

Summary: Endophytic fungi in the Xylariales exhibit high bioactivity and broad host ranges, with genomic factors related to secondary metabolite gene clusters (SMGCs) influencing symbiotic interactions and ecological roles. Xylariaceae endophytes show increased metabolic diversity, gene duplications, horizontal gene transfers (HGTs), and SMGCs compared to Hypoxylaceae species, likely driven by selection pressures from host and substrate generalism. The study highlights the importance of microbial symbioses in driving fungal metabolic diversity and facilitating symbiosis with phylogenetically diverse hosts.

Summary: Foliar fungal endophytes are symbionts that inhabit healthy plant tissues and influence plant health and productivity. Endophyte communities are more similar in closely related hosts and their tolerance to polyphenolic compounds is associated with their degree of specialization to oaks in nature. Oak-associated fungi showed tolerance to phenolics, suggesting that variation in phenolic abundance and composition among oaks influences endophyte host associations.
