Miq. is a deciduous arbor and a member of Sabiaceae. It is one of the rare and protected plants with outstanding ornamental and economic value in Jiangsu, China. In addition to the resource values indicated above, there are numerous other elements that require additional research, including the chloroplast (cp) genomic information. In this work, the complete cp genome sequence of was assembled and characterized for the first time. The complete cp genome of was 159,950 base pair (bp) in length, including a large single-copy (LSC) region of 87,147 bp, a small single-copy (SSC) region of 18,015 bp, and the inverted repeats (IRs) region of 27,394 bp. It contains 131 genes, including 37 tRNA genes, eight rRNA genes, 85 protein-coding genes, and one pseudogene. The overall GC content of cp genome was 37.95%. The placement of in the phylogenetic tree constructed using the complete cp genome is largely congruent with previous studies. The clustering of is non-monophyletic, aligns more closely with existing morphological taxonomic studies, thereby enhancing the scholarly and scientific nature of this research.
米槭是一种落叶乔木，属于清风藤科。它是中国江苏具有突出观赏和经济价值的珍稀保护植物之一。除了上述资源价值外，还有许多其他因素需要进一步研究，包括叶绿体（cp）基因组信息。在这项工作中，首次组装并表征了[植物名称]的完整cp基因组序列。[植物名称]的完整cp基因组长度为159,950碱基对（bp），包括一个87,147 bp的大单拷贝（LSC）区域、一个18,015 bp的小单拷贝（SSC）区域和一个27,394 bp的反向重复（IR）区域。它包含131个基因，包括37个tRNA基因、8个rRNA基因、85个蛋白质编码基因和一个假基因。[植物名称]cp基因组的总体GC含量为37.95%。在使用完整cp基因组构建的系统发育树中，[植物名称]的位置与先前的研究基本一致。[植物名称]的聚类不是单系的，与现有的形态分类学研究更紧密地对齐，从而增强了本研究的学术性和科学性。
