is commonly called lily magnolia and its buds are used as the herbal medicine; it is an endemic species to China. In this study, the complete chloroplast genome of has been presented and annotated. The whole chloroplast (cp) genome is 158,177 bp in size, which exhibits a large single-copy region (LSC) of 88,134 bp, a small single-copy region (SSC) of 19,876 bp and two inverted-repeat regions (IRs) 25,706 bp in each one. The overall nucleotide composition is: 30.0% of A, 30.9% of T, 19.9% C, and 19.2% G, with the GC content of the chloroplast genome 39.1%. The cp genome of contains 129 genes, which includes 86 protein-coding genes (PCGs), 35 transfer RNA (tRNAs), and 8 ribosome RNA (rRNAs). The maximum-likelihood (ML) tree result showed that is closely related to two Magnoliaceae family species of and in phylogenetic relationship. This complete chloroplast genomes will be useful for medicinal study in the future.
通常被称为辛夷，其花蕾被用作草药；它是中国特有的物种。在本研究中，已经展示并注释了其完整的叶绿体基因组。整个叶绿体（cp）基因组大小为158,177 bp，具有一个88,134 bp的大单拷贝区域（LSC）、一个19,876 bp的小单拷贝区域（SSC）以及两个各为25,706 bp的反向重复区域（IRs）。总体核苷酸组成是：A占30.0%，T占30.9%，C占19.9%，G占19.2%，叶绿体基因组的GC含量为39.1%。该物种的cp基因组包含129个基因，其中包括86个蛋白质编码基因（PCGs）、35个转运RNA（tRNAs）和8个核糖体RNA（rRNAs）。最大似然（ML）树结果表明，在系统发育关系上，该物种与木兰科的两个物种Magnolia officinalis和Magnolia biondii密切相关。这个完整的叶绿体基因组在未来的药用研究中将是有用的。
