It belongs to the genus\n Pteroceltis<\/jats:italic>\n in the family Cannabaceae, and is an economically and culturally valuable fiber-producing tree species. We integrated PacBio HiFi, Oxford Nanopore Technology (ONT), and Hi-C chromatin conformation capture data to generate a near-complete telomere-to-telomere genome assembly of a millennium-old\n P. tatarinowii<\/jats:italic>\n tree. The final assembly spanned approximately 689\u2009Mb, with a contig N50 of 35.0\u2009Mb; 99.88% of the sequences were successfully mapped onto chromosomes, with only two gaps remaining in the genome, showing a marked improvement in assembly continuity over previously published\n P. tatarinowii<\/jats:italic>\n assemblies. We predicted a total of 47,241 protein-coding genes; repetitive sequences accounted for 48.37% of the genome, with long terminal repeat retrotransposons as the dominant component (18.92%). Benchmarking Universal Single-Copy Orthologs assessment confirmed genome completeness of 98.6% and gene annotation completeness of 98.7%. We resolved key complex genomic regions, including telomeres and centromeres, and this high-quality assembly provided a foundational genomic resource to clarify the taxonomic status of\n P. tatarinowii<\/jats:italic>\n and formulate scientific genetic conservation strategies for this endangered relict species.\n <\/jats:p>","DOI":"10.1038\/s41597-026-08097-z","type":"journal-article","created":{"date-parts":[[2026,8,22]],"date-time":"2026-08-22T09:24:06Z","timestamp":1787390646000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Near-complete telomere-to-telomere genome assembly of a millennium-old ancient Pteroceltis tatarinowii (Qingtan, Cannabaceae) tree"],"prefix":"10.1038","author":[{"given":"Zhi-Cheng","family":"Wu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Jing","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Er-Wen","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong","family":"Lv","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji-Tong","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"En-Teng","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling-Yun","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Tong","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,8,22]]},"container-title":["Scientific Data"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.nature.com\/articles\/s41597-026-08097-z","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"}],"deposited":{"date-parts":[[2026,8,22]],"date-time":"2026-08-22T09:24:06Z","timestamp":1787390646000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.nature.com\/articles\/s41597-026-08097-z"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,8,22]]},"references-count":0,"alternative-id":["8097"],"URL":"https:\/\/doi.org\/10.1038\/s41597-026-08097-z","relation":{},"ISSN":["2052-4463"],"issn-type":[{"value":"2052-4463","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,8,22]]},"assertion":[{"value":"19 March 2026","order":1,"name":"received","label":"Received","group":{"name":"ArticleHistory","label":"Article History"}},{"value":"10 August 2026","order":2,"name":"accepted","label":"Accepted","group":{"name":"ArticleHistory","label":"Article History"}},{"value":"22 August 2026","order":3,"name":"first_online","label":"First Online","group":{"name":"ArticleHistory","label":"Article History"}},{"value":"The authors declare no competing interests.","order":1,"name":"Ethics","label":"Competing interests","group":{"name":"EthicsHeading","label":"Ethics"}}]}}
