Through comprehensive molecular phylogenetic analysis and detailed morphological examination, seven fungal species were identified: Sesquicillium lasiacidis, Sesquicillium essexcoheniae, Trichoderma asperellum, Trichoderma paraobovatum sp. nov., Trichoderma rifaii, Trichoderma sparsum, and Trichoderma texanum. Molecular identification was conducted using ITS and LSU regions for Sesquicillium and ITS, EF1a, and RPB2 loci for Trichoderma, with phylogenetic analysis confirming their placement alongside type strains. These findings expand the known geographic distributions of these species and highlight the potential of lichen-associated fungi as reservoirs of bioactive compounds and enzymes with industrial and pharmaceutical applications.","PeriodicalId":18825,"journal":{"name":"Mycobiology","volume":"53 4","pages":"435-449"},"PeriodicalIF":2.0,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12308888/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144753869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their ecological importance, studies on the distribution and genetic structure of S. depressa in South Korea remain limited. This study aims to examine this knowledge gap by analyzing the ecological preferences, genetic diversity, and distribution change of S. depressa under future climate scenarios. Field surveys were conducted across 96 sites, including 66 sites on Jeju Island and 30 islands, revealing a highly restricted distribution with the species present at only 12 sites in four islands. Analysis of bioclimate variables indicated that warmer temperatures and lower temperature seasonality significantly influence the distribution of S. depressa. Population genetic analyses, based on ITS sequences from 45 samples, identified 17 haplotypes and revealed moderate regional differentiation, with significant isolation-by-distance but no isolation-by-environment effect. Species distribution modeling predicts potential range expansion under future climate scenarios. These findings highlight the ecological sensitivity of S. depressa to temperature gradients and its potential as a bioindicator for subtropical ecosystem shifts, emphasizing the need to conserve genetically diverse populations to enhance resilience against climate change.","PeriodicalId":18825,"journal":{"name":"Mycobiology","volume":"53 4","pages":"412-420"},"PeriodicalIF":2.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12308876/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144753868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The native plant species thriving in these habitats play a crucial role in preventing coastal erosion. A total of 138 fungal endophytes were isolated from two plant groups: basalt-dwelling lithophytes (83 isolates) and sandy soil-dwelling halophytes (55 isolates). The host plants belonged to nine orders, 11 families, 14 genera, and 14 species. Molecular identification and phylogenetic analysis based on internal transcribed spacer (ITS) regions classified the isolates into six fungal classes, 11 orders, 15 families, and 22 genera. The dominant classes were Sordariomycetes (51.45%), Eurotiomycetes (26.09%), Dothideomycetes (18.84%). The dominant genera were Penicillium (33.58%), Fusarium (16.79%), Aspergillus (15.33%), and Talaromyces (10.22%). Endophyte diversity, as measured by Shannon's diversity index (2.131), was higher in basalt-habitat lithophytes than in sandy soil-dwelling halophytes.

Transcriptome analysis further revealed that low Na+ concentrations (10 mmol/L) promoted the accumulation of soluble sugars (7.63 ± 0.54 mg/g) and upregulated the expression of pertinent genes, thereby accelerating mycelial growth. On the other hand, high Na+ concentrations (100 mmol/L) led to H2O2 accumulation (12.18 ± 0.24 μmol/g), causing toxicity in S. baumii mycelia. High Na+ concentrations also significantly boosted the production of valuable metabolites, such as triterpenoids (19.65 ± 0.22 mg/g), although the exact mechanisms remain to be elucidated.
