is a highly valued woody herb medicinal plant belonging to the family Araliaceae, which is also the popular edible plant in China. In this paper, the chloroplast genome of was completed. The complete chloroplast genome of was 156,768 bp in length as a circle. It contained a large single-copy (LSC) region of 86,756 bp, a small single- copy (SSC) region of 18,154 bp and separated by two inverted repeat (IR) regions of 25,929 bp. The base compositions of chloroplast genome is uneven and the overall nucleotide composition is: A (30.7%), T (31.4%), C (19.3%) and G (18.6%), with a total G + C content (39.4%). It comprised 134 genes, including 89 protein-coding genes (PCGs), 37 transfer RNA (tRNA) genes and 8 ribosomal RNA (rRNA) genes. 8 PCG genes species, 7 tRNA genes species and 4 rRNA species were found duplicated in the IR regions. The phylogenetic analysis result shown that the chloroplast genome of is closest to of the family Araliaceae in this study by the maximum-likelihood (ML) method. The complete chloroplast genome of can provide more genomics information for further research on the species in China.
是一种极具价值的木本草本药用植物，隶属于五加科，也是中国广受欢迎的食用植物。本文完成了其叶绿体基因组测序。其完整叶绿体基因组呈环状，长度为156,768 bp。它包含一个86,756 bp的大单拷贝（LSC）区域、一个18,154 bp的小单拷贝（SSC）区域，由两个25,929 bp的反向重复（IR）区域隔开。叶绿体基因组的碱基组成不均衡，总体核苷酸组成为：A（30.7%）、T（31.4%）、C（19.3%）和G（18.6%），G + C总含量为39.4%。它包含134个基因，包括89个蛋白质编码基因（PCG）、37个转运RNA（tRNA）基因和8个核糖体RNA（rRNA）基因。在IR区域发现8个PCG基因种类、7个tRNA基因种类和4个rRNA种类存在重复。系统发育分析结果表明，通过最大似然法（ML），该植物的叶绿体基因组在本研究中与五加科的[具体植物名称未给出]最为接近。该植物完整的叶绿体基因组可为中国该物种的进一步研究提供更多基因组学信息。
