is an endangered tree endemic to China with high medicinal values. In this study, the complete chloroplast genome of was assembled using Illumina high-throughput sequencing technology. The whole chloroplast genome was 136,877 bp long with an asymmetric base composition (32.6% A, 17.6% C, 17.4% G and 32.4% T). The genome annotation predicted a total of 114 genes, including 82 protein-coding genes, 28 tRNA genes, and four rRNA genes. The neighbour-joining phylogenetic analysis based on 41 complete chloroplast genome sequences showed that was more closely related to the congeneric . The assembled chloroplast genome of will provide useful genomic data both for the phylogenetic research of and the conservation of this endangered species.
是中国特有的濒危树种，具有很高的药用价值。在本研究中，利用Illumina高通量测序技术组装了该树种的完整叶绿体基因组。整个叶绿体基因组长度为136,877 bp，碱基组成不对称（A占32.6%，C占17.6%，G占17.4%，T占32.4%）。基因组注释共预测出114个基因，包括82个蛋白质编码基因、28个tRNA基因和4个rRNA基因。基于41个完整叶绿体基因组序列的邻接法系统发育分析表明，该树种与同属的关系更为密切。组装得到的该树种叶绿体基因组将为其系统发育研究和这一濒危物种的保护提供有用的基因组数据。
