has a thin, wood, grayish-yellow root and is reputed to possess medicinal value. This study employs the method using high-throughput sequencing data to assemble the complete chloroplast genome for this species. The total genome is 155,320 bp in length, containing a large single-copy region of 85,280 bp, a small single-copy region of 17,468 bp, a pair of inverted repeat regions of 26,286 bp, and has a GC content of 37.8%. The genome encodes 113 unique genes, of which there are 79 protein-coding, 30 tRNA, and four rRNA genes. In addition, 18 genes contained introns, , , and are coded for by two exons, and is identified as a trans-splicing gene. Phylogenetic analysis results strongly suggest that is closely related to . This study provides valuable genetic information to facilitate reliable identification.
它有一条细的、木质的、灰黄色的根，据说具有药用价值。本研究采用高通量测序数据的方法来组装该物种的完整叶绿体基因组。基因组全长155320bp，包含一个85280bp的大单拷贝区域、一个17468bp的小单拷贝区域、一对26286bp的反向重复区域，GC含量为37.8%。该基因组编码113个独特基因，其中有79个蛋白质编码基因、30个tRNA基因和4个rRNA基因。此外，18个基因含有内含子， 、 和 由两个外显子编码， 被鉴定为一个反式剪接基因。系统发育分析结果强烈表明 与 密切相关。本研究提供了有价值的遗传信息，以促进可靠的鉴定。
