Our phylogenetic analysis revealed that Mbp1 and Swi6 are widely conserved among various fungi, whereas Swi4 is a protein specific for Saccharomycotina. In <em>P. ostreatus</em>, two putative clade A APSES family transcription factors, protein ID 83192 and 134090, were found and identified as Mbp1 and Swi6, respectively.

Disruption of <em>mbp1</em> significantly decreased the growth rate and shortened aerial hyphae, suggesting that Mbp1 is involved in mycelial growth, especially aerial hyphal growth. Furthermore, thinner cell walls, decreased relative percentage of β-glucan, and downregulation of all β-glucan synthase genes were observed in Δ<em>mbp1</em> strains. Therefore, Mbp1 plays an essential role in β-glucan synthesis regulation in <em>P. ostreatus</em>. Disruption of <em>mbp1</em> also impacted the expression profiles of chitin synthase genes, septum formation, and sensitivity to a chitin synthesis inhibitor, suggesting that Mbp1 also regulates chitin synthesis.

In this study, we systematically phenotyped 16 dikaryotic strains for aspects of mushroom development and 18 monokaryotic strains for lignocellulose degradation. There was considerable heterogeneity among the strains regarding these phenotypes. The majority of the strains developed mushrooms with varying morphologies, although some strains only grew vegetatively under the tested conditions.

Moreover, the related species <em>Schizophyllum fasciatum</em> was sequenced. Although there was considerable genetic variation between the genome assemblies, the genes related to mushroom formation and lignocellulose degradation were well conserved. These sequenced genomes, in combination with the high phenotypic diversity, will provide a solid basis for functional genomics analyses of the strains of <em>S. commune</em>.</p></div>","PeriodicalId":55135,"journal":{"name":"Fungal Genetics and Biology","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1087184524000501/pdfft?md5=4b9314edeb77dde82d99b95832663019&pid=1-s2.0-S1087184524000501-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141617609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
