The first complete chloroplast genome sequence of , a herbaceous perennial, and its phylogenetic position relative to a member of the annual weedy and woody perennial species of were reported in this study. Here, we assembled the complete plastome sequence of 151,967 base pairs (bp) in length, comprising 84,251 bp of a large single copy (LSC) and 18,184 bp (SSC) of small single copy confined between 24,766 bp of inverted repeats (IR). The genome contained 130 genes, including 87 protein-coding genes, six ribosomal RNA, and 37 transfer RNA genes. The overall GC content was 37.6% (LSC, 35.8%; SSC, 31.5%; IRs, 43.0%). Phylogenetic analysis confirmed that perennial is sister to the clade containing the weedy species of .
本研究报道了一种多年生草本植物的首个完整叶绿体基因组序列，以及它相对于一年生杂草和多年生木本植物中一个成员的系统发育位置。在这里，我们组装了长度为151,967碱基对（bp）的完整质体基因组序列，其中包括84,251 bp的大单拷贝（LSC）和18,184 bp的小单拷贝（SSC），它们被24,766 bp的反向重复序列（IR）隔开。该基因组包含130个基因，包括87个蛋白质编码基因、6个核糖体RNA和37个转运RNA基因。总体GC含量为37.6%（LSC为35.8%；SSC为31.5%；IRs为43.0%）。系统发育分析证实，多年生植物是包含杂草物种的分支的姐妹种。
