In this study, we focused on two Aspergillus oryzae hydrophobins, whose biological functions were unclear. We found that hydrophobins RolA and HypB are highly expressed. We created strains with disruption of one of the respective genes, ΔrolA and ΔhypB, and examined their phenotypes under various stress conditions. The two strains had different phenotypes under stress conditions that affected the cell wall surface function. Self-assembled structures on the conidial surface were absent in the ΔrolA strain, whereas specific structures on the surface of aerial hyphae were absent in the ΔhypB strain. Colony hydrophobicity was lower in the ΔhypB strain than in the control CNT strain, whereas conidial surface hydrophobicity was lower in the ΔrolA strain than in the control CNT strain. These findings indicate that RolA and HypB share similar functions on the cell surface, but RolA functions mainly on the conidial surface, whereas HypB functions mainly on the surface of aerial hyphae.","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":"67 4","pages":"142-152"},"PeriodicalIF":1.4,"publicationDate":"2026-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13408789/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148620739","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, their inhabitation and ecology on twig litter remain poorly understood. Therefore, myxomycete species richness and diversity in a forest, canopy tree species and types, and the microenvironmental factors influencing their distribution were assessed. In a natural mid-temperate forest of western Japan, twig litter was seasonally sampled on the forest floor under nine canopy trees selected by different tree types and large, long-lived trees. Using moist chamber cultures (MCs), twigs were incubated to induce myxomycete fruiting. As a result, 60% of the 380 MCs produced fruiting bodies of 33 myxomycete taxa from 21 genera. Ordination of 18 myxomycete communities using non-metric multidimensional scaling distinguished two seasonal groups. The arrangement of the communities was significantly correlated with environmental factors, such as twig pH, soil pH, and diameter at breast height. Large, long-lived trees had characteristically distinct ecological habitats for myxomycetes on twig litter. Members of Cribrariales and Trichiales were dominant on coniferous twigs, whereas Physarales dominated evergreen twigs. This study suggests that canopy trees shape myxomycete communities as a microhabitat in a forest ecosystem, and a mid-temperate forest maintains a high species diversity of myxomycetes, making it an important biodiversity hotspot.","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":"67 3","pages":"94-104"},"PeriodicalIF":1.4,"publicationDate":"2026-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13230480/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148163669","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}

As the open reading frame of stcX has been undefined, we deleted three putative genes adjacent to stcW simultaneously. Deletion of the region did not significantly impact growth rate across various growth conditions compared to the control strain. Chemical analyses revealed no significant change in ST production in the deletion strain compared to the control. Furthermore, the three transcripts were largely undetectable during ST biosynthesis, and the expression of other ST cluster genes was unaffected by the deletion. Our results suggest that these genes are not essential for ST biosynthesis in A. nidulans, indicating that the cluster should be delineated to exclude stcX.","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":"67 3","pages":"88-93"},"PeriodicalIF":1.4,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13230479/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148163709","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}

Myxomycetes that grow on dead trees disperse spores and reuse dead trees as substrate for reproduction. Compared to research on the interactions between myxomycetes and organisms other than Collembola (e.g., Acari, Diptera, and Coleoptera), studies on the interactions between myxomycetes and collembolans on dead trees are limited. To clarify the relationship between them, myxomycetes and nearby collembolans were collected through the aspiration method. This method allows the simultaneous collection of myxomycete fruiting bodies and collembolans. In the laboratory, the collected specimens were observed under a microscope, and the population density and spore-feeding behavior of collembola were analyzed and compared for each myxomycete. In our study, we identified ten families of collembola residing among myxomycetes on dead trees at the collection site. Notably, eight of these families were observed to consume spores and various components of the fruiting bodies of myxomycetes. Additionally, we conducted an analysis of the interrelationships among three species of myxomycetes, focusing on variations in collembolan populations and their feeding rates. This research represents the first quantitative investigation into the relationship between myxomycetes and collembolans, employing field-based observations and collections to yield our findings.","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":"67 2","pages":"32-42"},"PeriodicalIF":1.4,"publicationDate":"2026-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13112063/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147776492","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}
