Management of fungal diseases can be achieved through an integrated disease management approach, including accurate identification of the causative agents. <em>Diaporthe</em> blight is a common disease of eggplant (<em>Solanum melongena</em>). Although <em>Diaporthe</em> <em>vexans</em> has been implicated as the causative agent, it was unclear until this study whether other <em>Diaporthe</em> species also contribute to this disease. In this study, leaf and fruit blights of eggplants were collected from different provinces in the Philippines. Through a polyphasic approach—morphological, cultural, pathogenicity, and multi-locus phylogenetic analyses of ITS, <em>TEF1-α</em>, <em>TUB2</em>, <em>CAL</em>, and <em>HIS3</em> coupled with genealogical concordance phylogenetic species recognition analyses—we identified six <em>Diaporthe </em>speciesfrom the <em>D. sojae</em> species complex and <em>D. arecae</em> species complex. Two novel species, <em>D. solani-melongenae </em>and <em>D. talong</em>, along with the re-validated <em>D.</em> <em>melongenae</em>, and known species, viz., <em>D. arecae</em>, <em>D.</em> <em>passifloricola</em>, and <em>D. vexans</em> were identified as the causative agents of <em>Diaporthe</em> leaf and fruit blight of eggplant in the Philippines. Additionally, we also provide evidence supporting the synonymization of <em>D. etinsidea </em>with <em>D. tulliensis</em>, <em>D. durionigena </em>with <em>D. rosae</em>, and <em>D. griceae</em> with <em>D. vexans</em>. Our study confirmed that <em>D. vexans</em> is the major causative agent of eggplant blight in the country. All <em>Diaporthe </em>species were found to be pathogenic to eggplant. The results of this study contribute to the understanding of the eggplant blight disease, its potential spread, and the development of more targeted management strategies.</p>","PeriodicalId":19111,"journal":{"name":"Mycological Progress","volume":"46 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140300671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
