Lysurus mokusin (L.f.) Fr., initially described and named ‘mo-ku-sin’ after pronunciation of Chinese ‘蘑菰蕈’ by the French missionary Cibot in 1774, is the first scientifically described fungus from China. To facilitate the correct application of its name, its typification and taxonomic study according to the current nomenclature code were carried out. The lectotype and epitype were designated, and mitochondrial genome and nuclear genome of the epitype specimen were assembled. The circulated mitochondria of L. mokusin totaled 101.1 kb, containing 26 tRNA and 16 protein-coding genes. Each nuclear haplotype contains 11 chromosomes with a total length of 33 Mb and 8/11 fragment contigs of 1.4 Mb. The BUSCO analysis suggested that the genome is 88.5% completed. This is the first genome reported for Lysurus. A high proportion of repeat sequences (ca. 16%) was detected and, after masking, 8 637 and 8 572 protein-coding genes were predicted for two haplotypes, respectively. The gene distribution shows a typical pattern of a “two-speed genome”. In addition, 27 non-redundant biosynthetic gene clusters (BGCs) were predicted, mainly distributed in Chr01, Chr04 and Chr06. Two BGCs are 100% homologous to known insecticidal and antimicrobial BGCs producing xenotetrapeptide and rhizomide. Our study provides a model for the typification of numerous early-described species lacking types in China."/>template{display:none;}.mag-rich-xref-fn { cursor: pointer;}//长视频$(document).ready(function(){if($("#showLongArticleVideo") && $("#showLongArticleVideo").length && $("#showLongArticleVideo").length>0){mag_ajax_update({ele_id:'showLongArticleVideo',url:mag_currentQikanUrl() + "/CN/article/showLongArticleVideo.do?id="+$("#articleId").val()});}});//可视化图谱$(document).ready(function(){if($("#showArticle_knowledgeMap") && $("#showArticle_knowledgeMap").length && $("#showArticle_knowledgeMap").length>0){jQuery.getJSON("/Jwxb/CN/lexeme/existsCnctstInArticle.do?articleID="+$("#articleId").val(), null, function(json){if(json.result){$("#showArticle_knowledgeMap").show();}});}});$(document).ready(function(){var metaDataStr = $.trim($("#article_metaJson").val());if(metaDataStr!=''){eval("window.metaData="+metaDataStr);}if(window.metaData && (!window.metaData.authorNotesCommon_cn && !window.metaData.authorNotesCorresp_cn && window.metaData.authorNotes_cn)){window.metaData.authorNotesCommon_cn = window.metaData.authorNotes_cn;}if(window.metaData && (!window.metaData.authorNotesCommon_en && !window.metaData.authorNotesCorresp_en && window.metaData.authorNotes_en)){window.metaData.authorNotesCommon_en = window.metaData.authorNotes_en;}var _nlmdtdXml = $("#article_nlmdtdXml").val();var magDir = _nlmdtdXml.replace(/\/[^\/]+$/,'');window.metaData.magDir = magDir;new mag_vue({ el: '#metaVue', //dataUrl: mag_currentQikanUrl() + '/EN/article/getRichHtmlJson.do?articleId='+$("#articleId").val(), data:window.metaData, loading:true, doTextFun:function(text){ return doDataJsonText(text);
