Plants release strigolactones, which trigger AM spore germination and hyphal branching, a process regulated by genes, such as <i>D27</i>, <i>CCD7</i>, <i>CCD8</i>, and <i>MAX1</i>. AM recognition by plants is mediated by receptor-like kinases (RLKs) and LysM domains, leading to the formation of arbuscules that optimize nutrient exchange.

Other hormones, such as salicylic acid, gibberellins, ethylene, jasmonic acid, and abscisic acid, also influence AM colonization and stress responses, further bolstering plant resilience. In addition to plant health, AM enhances soil health by improving microbial diversity, soil structure, nutrient cycling, and carbon sequestration. This symbiosis supports soil pH regulation and pathogen suppression, offering a sustainable alternative to chemical fertilizers and improving soil fertility.

The Ka/Ks values for all 15 core PCGs were < 1, suggesting that these genes were all subject to purifying selection. Comparative mitogenome analysis showed that introns contributed the most to the size variation of <i>Diaporthe</i> mitogenomes. Frequent intron loss/gain events were detected to have occurred in the <i>cox1</i> gene during the evolution of the <i>Diaporthales</i> mitogenomes. Although the mitogenomes of 13 species from <i>Diaporthales</i> had undergone large-scale gene rearrangements, six mitogenomes of <i>Diaporthe</i> species had identical gene arrangements. Phylogenetic analysis based on combined mitochondrial gene datasets showed that the six <i>Diaporthe</i> species formed well-supported topologies. To our knowledge, this study is the first report on the mitogenomes of <i>D.phaseolorum</i> ZM33-4 and <i>Diaporthe</i> sp. ZM41-5, as well as the first comparison of mitogenomes among <i>Diaporthe</i> species. Our findings will further promote investigations of the genetics, evolution and phylogeny of the <i>Diaporthe</i> species.</p>","PeriodicalId":54345,"journal":{"name":"Ima Fungus","volume":"16 ","pages":"e140572"},"PeriodicalIF":5.2,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11889515/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143588125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
