The plastome sequences of and are completed in family Scrophulariaceae. The structure of two plastomes shows similar characteristic with the typical plastome of angiosperm. The lengths of two plastomes are 153,631bp and 152,436bp, respectively. They are divided into LSC region (84,454bp and 83,542bp) and SSC region (17,929bp and 17,938bp) by two IR regions (25,624bp and 25,478bp). Both plastomes contain 113 genes including 79 protein coding genes, 30 tRNA genes and 4 rRNA genes. Eight protein-coding, seven tRNA and four rRNA genes are duplicated in the IR regions. Eighteen genes have one or two intron(s). The overall A-T contents of two genomes are 62.0% and 61.9%, respectively. The A-T content in the non-coding (both 64.5%) is higher than in the coding (60.2% and 60.1%) region. Forty-four and forty-one simple sequence repeat (SSR) loci are identified in the and plastomes, respectively. In phylogenetic analysis, the genus shows closed relationship with Plantaginaceae.
玄参科中[物种1]和[物种2]的质体基因组序列已完成测定。两个质体基因组的结构与被子植物典型质体基因组具有相似特征。两个质体基因组的长度分别为153,631bp和152,436bp。它们被两个反向重复区域（25,624bp和25,478bp）分为大单拷贝区域（84,454bp和83,542bp）和小单拷贝区域（17,929bp和17,938bp）。两个质体基因组均包含113个基因，其中包括79个蛋白质编码基因、30个tRNA基因和4个rRNA基因。8个蛋白质编码基因、7个tRNA基因和4个rRNA基因在反向重复区域中重复。18个基因含有1个或2个内含子。两个基因组的总体A-T含量分别为62.0%和61.9%。非编码区的A-T含量（均为64.5%）高于编码区（分别为60.2%和60.1%）。在[物种1]和[物种2]的质体基因组中分别鉴定出44个和41个简单序列重复（SSR）位点。在系统发育分析中，[属名]属与车前科显示出密切的关系。
