Poljakov is an endemic and endangered herb in China. In this study, we sequenced and analyzed the complete chloroplast genome of this species. Sequencing revealed the genome to be 151,179 bp in length, containing a large single copy region (82,862 bp), a small single copy region (18,377 bp), and a pair of inverted repeat regions (24,970 bp each). Our analyses demonstrated that it contained 133 genes, including 87 protein-coding genes, 37 transfer RNA genes, eight ribosomal RNA genes, and one pseudogene (). Furthermore, we found the genome to have an overall GC content of 37.4%. A phylogenetic analysis indicated that and clustered together as sister group to and clade.
多枝黄耆是中国的一种特有且濒危的草本植物。在本研究中，我们对该物种的叶绿体全基因组进行了测序和分析。测序结果显示该基因组长度为151,179 bp，包含一个大单拷贝区域（82,862 bp）、一个小单拷贝区域（18,377 bp）和一对反向重复区域（各24,970 bp）。我们的分析表明它包含133个基因，包括87个蛋白质编码基因、37个转运RNA基因、8个核糖体RNA基因和一个假基因（）。此外，我们发现该基因组的总体GC含量为37.4%。系统发育分析表明，与聚在一起，形成了与和分支的姐妹群。
