We found that treatment with 10 mmol/L Na+ (Na10) significantly increased the growth rate (0.41 ± 0.01 cm/d) and biomass (4.27 ± 0.05 g/L) of S. baumii mycelia, surpassing the control (Ck) group by 3.14% and 4.06%, respectively. In contrast, treatment with 100 mmol/L Na+ (Na100) resulted in a significant reduction in growth rate (0.34 ± 0.01 cm/d) and biomass (3.25 ± 0.02 g/L) of S. baumii mycelia compared to the Ck group. 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. Overall, we suggest an effective approach for accelerating mycelial growth cycles and enhancing the production of high-value bioactive compounds from S. baumii.","PeriodicalId":18825,"journal":{"name":"Mycobiology","volume":"53 3","pages":"331-337"},"PeriodicalIF":1.6,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12077424/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144079139","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}

Many measures of PWN management have been implemented, including using the nematophagous fungus Esteya vermicola as a biological control agent. However, understanding on the interaction between this fungus and pine trees is still limited. This study aimed to evaluate the effects of resinous compounds on spore germination and mycelial growth of E. vermicola in vitro. Research results showed that resinous compounds from pine trees significantly affect spore germination and mycelial growth of E. vermicola. In which, (+)α-pinene, (-)α-pinene, and (-)limonene completely inhibited spore germination and mycelial growth, with 100% of spore germination inhibition rate (SGIR) and mycelial growth inhibition rate (MGIR). The mixture of 14 resinous compounds also indicated potent inhibition of spore germination and mycelial growth of E. vermicola, with 100% and 91.8% SGIR and MGIR, respectively. These results suggest that trunk injection of spore suspension of E. vermicola to pine tree could be unsuccessful and ineffective for the control of pine wilt disease.","PeriodicalId":18825,"journal":{"name":"Mycobiology","volume":"53 3","pages":"314-320"},"PeriodicalIF":1.6,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11983573/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143972266","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}

However, based on cultural and morphological characteristics strain KNUF-23-236 differs from S. aurantiacum and S. album by having white-to-yellow colonies without reddish pigmentation, smaller hyphae (1.4-3.4 μm vs. 1.6-4.8 μm and 3.2-8.0 μm, respectively), arthrospores that transition from hyaline to brown rather than remaining consistently hyaline, and oval, septate chlamydospores that form singly or in chains, without branching.

One of the fungi was found to produce a mycotoxin called zearalenone, which is known to be a reproductive system disruptor. The presence of zearalenone was further confirmed using an authentic standard and a series of tandem mass spectrometry approaches. ITS sequencing identified the zearalenone-producing endophytic fungus as Talaromyces, showing sequence similarity to various species within this genus.

The strain KNUF-22-094T stands out among other Microascus species due to its distinctive conidiogenous cells and conidial size ranges. The conidiogenous cells of KNUF-22-094T measured 2.3-4.3 × 2.0-3.6 µm, notably smaller than those of M. rothbergiorum (7.5-11.5 × 2.5-4.5 µm), M. sparsimycelialis (5.0-10.0 × 3.0-5.0 µm), which is considerably larger in both dimensions. For the conidial structures, conidia measured 2.6-4.8 × 2.6-4.4 µm, falling within a distinct range that is smaller than those of M. rothbergiorum (4.0-5.5 × 3.5-4.5 µm), M. verrucosus (5.0-7.0 × 4.5-6.0 µm), and M. restrictus (4.5-6.0 × 4.0-5.5 µm), but comparable in size to M. murinus, which tends to be more elongated (4.0-6.0 × 1.5-1.9 µm). The phialides of KNUF-23-321CT are globose, with a notably broad length range of 3.7-22.5 µm and a width of 0.9-1.5 µm, making it one of the most variable in length compared to species like T. album (3.5-10 µm) and T. endophyticum (1.3 ± 0.2 µm, 4.1 µm on average). Phylogenetic analyses using a multi-locus sequences supported to confirm their distinctness under the genus Microascus and Tolypocladium species.

The infrageneric classification of the genus Penicillium has been studied with comparison of morphological and phylogenetical features, derived into two subgenus, 32 sections, and 89 series. In this study, 11 fungal strains were isolated from freshwater environments, plant litter, and nearby substrates in Korea and were identified as previously unreported species. The internal transcribed spacer (ITS) regions, β-tubulin (BenA), calmodulin (CaM), and RNA polymerase II subunit (RPB2) genes were analyzed for phylogenetic analyses. A neighbor-joining tree was then constructed using the concatenated DNA sequences, and the strains were compared with closely related species of the genus Penicillium. The strain clustered into distinct phylogenetic lineages, confirming their classification as P. contaminatum, P. jinfoshanicum, P. xuanhanense, and P. soppii.
