: Lindl. & Paxton is an ornamental tree species native to North China. Research on the mitochondrial genome can elucidate the evolution and biological characteristics of and better protect this important species. : This work aimed to clarify the evolutionary and phylogenetic links by sequencing, assembling, annotating, and analyzing the entire mitochondrial genome of . The single-loop structure that made up the mitochondrial genome had a total length of 657,640 bp and a GC content of 44.52%. In total, 37 unique protein-coding genes, 20 tRNA genes, and 3 rRNA genes were identified. Numerous repeat sequences and migrating fragments of chloroplast sequences were found. Using the mitochondrial protein-coding genes to construct evolutionary trees, it was found that the closest relative of is (Lingelsh.) Kiew. : This research represents the first comprehensive set of data on the mitochondrial genome of an ancient (>500 yr) specimen. In addition to elucidating the biological characteristics of . The findings contribute to the Oleaceae mitochondrial genome database and offer valuable insights for future studies in molecular breeding, evolutionary biology, and genetic diversity conservation.
: Lindl. & Paxton是一种原产于中国北方的观赏树种。对线粒体基因组的研究可以阐明其进化和生物学特性，并更好地保护这一重要物种。: 这项工作旨在通过对的线粒体全基因组进行测序、组装、注释和分析，来阐明其进化和系统发育联系。构成线粒体基因组的单环结构全长657,640 bp，GC含量为44.52%。总共鉴定出37个独特的蛋白质编码基因、20个tRNA基因和3个rRNA基因。发现了大量重复序列和叶绿体序列的迁移片段。利用线粒体蛋白质编码基因构建进化树，发现的最亲近的亲属是(Lingelsh.) Kiew。: 本研究代表了关于一个古老(>500年)标本的线粒体基因组的第一套全面数据。除了阐明的生物学特性外。这些发现为木犀科线粒体基因组数据库做出了贡献，并为未来分子育种、进化生物学和遗传多样性保护研究提供了有价值的见解。
