Schltr. is a traditional medicine plant in southwestern China. In this study, we characterize the complete chloroplast (cp) genome of based on next-generation sequencing. The cp genome is 154,140 bp in size with an overall GC content 38.2%, including a large single-copy (LSC) region (84,941 bp), a small single-copy (SSC) region of 17,619 bp, and two inverted repeats (IRs) regions, each of 25,790 bp. A total of 130 genes (85 protein-coding genes, 8 ribosomal RNA (rRNA) genes, and 37 transfer RNA (tRNA genes)) are annotated in the whole chloroplast genome, containing 113 unique genes (79 unique CDSs, 30 unique tRNAs, and 4 unique rRNAs). The phylogenetic analysis indicated that formed a monophyletic clade with the same genus plant , showing that they have close relationship. The complete chloroplast genome of provides valuable genomic information for the phylogeny, molecular identification and sustainable utilization of this species.
Schltr.是中国西南部的一种传统药用植物。在本研究中，我们基于二代测序对其完整叶绿体（cp）基因组进行了特征分析。该cp基因组大小为154,140 bp，总体GC含量为38.2%，包括一个大单拷贝（LSC）区域（84,941 bp）、一个小单拷贝（SSC）区域17,619 bp以及两个反向重复（IRs）区域，每个区域为25,790 bp。在整个叶绿体基因组中总共注释了130个基因（85个蛋白质编码基因、8个核糖体RNA（rRNA）基因和37个转运RNA（tRNA）基因），包含113个独特基因（79个独特的编码序列、30个独特的tRNA和4个独特的rRNA）。系统发育分析表明，Schltr.与同属植物形成一个单系分支，表明它们具有密切的关系。Schltr.的完整叶绿体基因组为该物种的系统发育、分子鉴定和可持续利用提供了有价值的基因组信息。
