Although species diversity within this genus has been increasingly documented in recent years, studies on its origin, evolutionary history, and biogeography remain limited. In this study, we compiled a global dataset of Hyphoderma sequences and reconstructed an updated phylogeny, divergence times, and biogeographic history of the genus Hyphoderma based on the internal transcribed spacer (ITS) region and nuclear large ribosomal subunit (nLSU) sequences. In addition, integrated morphological and phylogenetic analyses revealed five new Hyphoderma species. Molecular clock estimates indicated that the ancestor of Hyphoderma likely originated in the Cretaceous, with a mean stem age of 117.76 Mya (95% HPD = 92.38-147.74 Mya). Biogeographic reconstruction further suggested that Asia is the most probable ancestral area of Hyphoderma species.

Leaf blight caused by Alternaria spp. is the most common disease of P. orientalis. However, no reports are currently available on the screening and application of biocontrol agents for controlling this disease. In this study, several Trichoderma isolates were obtained from ancient P. orientalis in Beijing. Based on morphological characteristics and phylogenetic analyses of the concatenated ITS, tef1-α and rpb2 loci, four Trichoderma species were identified, including T. citrinoviride, T. obovatum, T. nordicum, and T. platycladi. Of these, T. platycladi is a species new to science, whereas T. nordicum and T. obovatum are new host records. Plate antagonism tests showed that representative strains of the four Trichoderma species exhibited significant inhibitory effects against colonies of Alternaria alternata and A. cantlous, the causal agents of leaf blight of ancient P. orientalis. Evaluation of the control effects on 1-year-old P. orientalis seedlings showed that these Trichoderma strains significantly controlled leaf blight, and T. nordicum CGMCC3.28772 exhibited the highest relative control effect under the same inoculation conditions.","PeriodicalId":48720,"journal":{"name":"Mycokeys","volume":"128 ","pages":"331-350"},"PeriodicalIF":3.6,"publicationDate":"2026-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12946831/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147327870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
