, which is an annual flowering plant in the plantain family Plantaginaceae, has commonly used as a Chinese herbal medicine to treat malaria in China. Here, the complete plastome of was successfully assembled based on genome skimming sequencing. The plastome of was 149,386 bp in length, comprising a pair of inverted repeats (IR; 24,946 bp) separated by a large single-copy (LSC) region (82,004 bp) and a small single-copy (SSC) region (17,490 bp). The plastid genome encoded 113 unique genes, consisting of 79 protein-coding genes, 30 tRNA genes, and four rRNA genes, with 19 duplicated genes in the IR regions. Six plastid hotspot regions (H-A, K-16, I-2, F-32, A-D and 15-1) were identified within . Phylogenetic analysis showed that the representative species from was monophyletic. and formed a maximum clade, followed by sister to .
，它是车前科的一年生开花植物，在中国通常被用作治疗疟疾的中药材。在此，基于基因组浅层测序成功组装了的完整质体基因组。的质体基因组长度为149,386 bp，由一对反向重复序列（IR；24,946 bp）组成，被一个大单拷贝（LSC）区域（82,004 bp）和一个小单拷贝（SSC）区域（17,490 bp）隔开。质体基因组编码113个独特基因，包括79个蛋白质编码基因、30个tRNA基因和4个rRNA基因，在IR区域有19个重复基因。在中鉴定出六个质体热点区域（H-A、K-16、I-2、F-32、A-D和15-1）。系统发育分析表明，来自的代表性物种是单系的。和形成了一个最大分支，其次是与的姐妹关系。
