Using ESI-MS, <sup>1</sup>H-NMR, and <sup>13</sup>C-NMR, we identified the active compound as cycloheximide. Cycloheximide had half-maximum inhibitory concentrations of 2.6 ng/mL for the inhibition of seed germination of <i>O. minor</i> and 2.5 µg/mL for that of the conidial germination of <i>A</i>. <i>oryzae</i>. Since cycloheximide is known to inhibit translation by interacting with ribosomal protein L28 (RPL28) in yeast, we investigated whether RPL protein of <i>O. minor</i> plays a critical role in the inhibition of <i>O. minor</i> seed germination. Our data suggested that <i>O. minor</i> RPL27A was not sensitive to cycloheximide by comparing it to the strain expressing <i>S. cerevisiae</i> RPL28. These findings suggest the presence of an unidentified mechanism by which cycloheximide hinders <i>O. minor</i> seed germination.</p>\u0000<p></p>\u0000<img alt=\"\" src=\"https://www.jstage.jst.go.jp/pub/jpestics/advpub/0/advpub_D23-038/figure/advpub_D23-038.png\"/>\u0000<span style=\"padding-left:5px;\">Fullsize Image</span>","PeriodicalId":16712,"journal":{"name":"Journal of Pesticide Science","volume":"24 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139055872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A field experiment was conducted for two years to study pendimethalin residues in the green fodder and silage of wheat and barley.
