is a perennial woody vine with nine species that had been originally placed in . These species of are economically and medically important. Limited information is available on the genomic characteristics of the chloroplasts of this genus. (Hance) J. Wen & Z. L. Nie 2014 contains 131 unique genes (86 protein-coding genes, 8 rRNAs, and 37 tRNAs). The complete chloroplast sequence contains 162,976 bp. The large single-copy region contains 89,291 bp; the small single-copy region contains 19,063 bp, and a pair of inverted repeat sequences is composed of 27,311 bp. There are 84 simple sequence repeat (SSR) loci in the complete chloroplast genome of , with mononucleotide, dinucleotide, trinucleotide, tetranucleotide and hexanucleotide SSRs of 58, 9, 6, 10 and 1, respectively. A total of 337 repeats were identified, including 172 forward repeats, three reverse repeats and 163 palindromic repeats. A phylogenetic analysis based on the complete genome data of the chloroplasts of 10 plant species indicated the monophyly of and determined the phylogenetic relationships of in . This study provides a reference for further studies on the taxonomy, identification, origin and evolution of and .
是一种多年生木质藤本植物，有九个物种，最初被归入 。这些 物种在经济和医学上都很重要。关于该属叶绿体的基因组特征的信息有限。（汉氏）J. 温 & Z. L. 聂2014年的研究包含131个独特基因（86个蛋白质编码基因、8个rRNA和37个tRNA）。叶绿体完整序列包含162,976 bp。大单拷贝区域包含89,291 bp；小单拷贝区域包含19,063 bp，一对反向重复序列由27,311 bp组成。在 的叶绿体完整基因组中有84个简单序列重复（SSR）位点，其中单核苷酸、二核苷酸、三核苷酸、四核苷酸和六核苷酸SSR分别有58、9、6、10和1个。总共鉴定出337个重复序列，包括172个正向重复序列、3个反向重复序列和163个回文重复序列。基于10种植物叶绿体完整基因组数据的系统发育分析表明了 的单系性，并确定了 中 的系统发育关系。本研究为进一步研究 和 的分类学、鉴定、起源和进化提供了参考。
