Molecular phylogenetic analysis revealed that both the fungal groups formed two clades within the M. pingshaense clade of the PARB clade, a lineage composed of generalist species that infect multiple orders of insects. Virulence bioassays on insects from three orders showed that both fungal groups were cricket-specific and distinctly different from closely related isolates of the PARB clade, despite the very shallow molecular phylogenetic divergence among them. The growth rates of both fungal groups on the agar medium were relatively slow, which seemed to reflect their narrow host range. PCR of virulence genes, such as DtxS1 and Mcl1, revealed that they were conserved among generalist PARB clade members but absent in both or one of the two gryllid-specialists. These results indicate that the two gryllid-specialist lineages have recently diverged from the ancestral generalist lineage, with concomitant divergence or loss of these virulence genes.

We hypothesize that endophytic P. capitalensis originates in tropical regions, which have higher host plant diversity than subtropical and temperate regions. We tested this hypothesis by examining the host range and genetic diversity in Indonesia, and the phylogeographic distribution of haplotypes according to the climatic conditions of Indonesia and elsewhere. A total of 434 plant species were sampled in the Bogor and Cibodas Botanical Gardens in Indonesia. A total of 244 ITS sequences of endophytic P. capitalensis from Indonesia and 133 previously collected from tropical, subtropical, and temperate regions of Japan were analyzed to assess genetic variation across climatic zones. Endophytic P. capitalensis was isolated from the leaves of 217 species from 182 genera in 35 families. The two Indonesian populations had higher haplotype diversities (16 and 11 haplotypes, respectively) than those at high-latitude sites. Assessment of haplotype phylogeny revealed a star-like pattern; Hap 2 was the dominant haplotype, being detected in 30 plant families in Indonesia, suggesting a rapid radiation of the species. The results demonstrate that P. capitalensis has higher genetic diversity in tropical than subtropical and temperate regions, supporting our hypothesis regarding its phylogenetic origin.","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":"66 5","pages":"290-299"},"PeriodicalIF":1.4,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13062961/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147675091","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}

To elucidate which Mycena species form mycorrhizal associations with orchids, fungal isolates of five Mycena species (M. epipterygia, M. haematopus, M. polygramma, M. pura, and Mycena sp.) from four sections (Calodontes, Fragilipedes, Hygrocyboideae, and Lactipedes) were cultured with the seeds of mycoheterotrophic orchids, including Gastrodia confusa, G. elata, G. nipponica, and G. pubilabiata. All five Mycena species stimulated seed germination in all four Gastrodia species. Mycena haematopus and M. polygramma had a high affinity for Gastrodia and induced protocorm formation in all of them and tuberization in seedlings of two of them. Phylogenetic analyses indicated that Mycena species that associate with Gastrodia are dispersed throughout the genus and do not form a monophyletic group. Gastrodia species differ in fungal specificity, with G. confusa having a narrow specificity for specific Mycena species, whereas G. pubilabiata and G. nipponica have a broader specificity with multiple Mycena lineages and non-Mycena species, Cyanotrama gypsea and Collybiopsis dichroa.

Here, we investigated a putative upstream regulator of this pathway, BmOPY2, in the maize pathogen Bipolaris maydis. Yeast two-hybrid analysis confirmed the interaction between BmOPY2 and BmSTE50, suggesting that BmOPY2 functions as an upstream regulator of the CHK1 MAPK pathway. To investigate the role of BmOPY2 in appressorium formation, we generated BmOPY2-disrupted (∆BmOPY2) mutants. These mutants formed appressoria normally on maize leaves, but did not form them on plastic Petri dishes. This suggests that BmOPY2 regulates appressorium formation via hydrophobic surface recognition but not via recognition of host-derived chemicals. Plant waxes or cutin monomers are recognized by other fungal pathogens, but these substances failed to restore appressorium formation in ∆BmOPY2 mutants. In comparison with the wild type, the ∆BmOPY2 mutants showed increased appressorium formation on intercellular spaces of maize leaves, suggesting that pectin-a component of these spaces-may promote this process. The addition of pectin restored appressorium formation by ∆BmOPY2 mutants on plastic surfaces. These findings reveal a novel dual regulation of appressorium formation in B. maydis, involving both BmOPY2-mediated hydrophobic surface recognition and a distinct pectin-dependent pathway.","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":"66 4","pages":"240-248"},"PeriodicalIF":1.4,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13062926/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147675033","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}
