(Oleaceae) is mainly distributed in the southwest of China and also planted in arboretums as an ornamental plant. In the present study, the plastome of was reconstructed using genome skimming sequencing, and the phylogeny analysis was inferred based on whole plastome data. The plastome of is 155,259 bp in length, comprising two copies of inverted regions (IR, 25,680 bp) separated by the large single copy (LSC, 86,534 bp) and small single copy (SSC, 17,365 bp) regions. The genome encodes 114 unique genes, including 80 different protein-coding genes, 30 tRNA genes, and four rRNA genes, with 20 duplicated genes in the IR regions. Phylogenetic analysis suggests that the representative species from is monophyletic, and is sister to within this genus.
（木犀科）主要分布于中国西南部，也作为观赏植物种植于植物园。在本研究中，利用基因组浅层测序重建了[植物名称]的质体基因组，并基于全质体数据进行了系统发育分析。[植物名称]的质体基因组长度为155,259 bp，由两个反向重复区域（IR，25,680 bp）组成，这两个区域被大单拷贝（LSC，86,534 bp）和小单拷贝（SSC，17,365 bp）区域隔开。该基因组编码114个独特基因，包括80个不同的蛋白质编码基因、30个tRNA基因和4个rRNA基因，其中有20个基因在IR区域重复。系统发育分析表明，来自[植物名称]的代表性物种是单系的，并且在该属内[植物名称]与[另一植物名称]是姐妹关系。
