H. Winkl.(Plantaginaceae) is a perennial herb with high medicinal value. To better understand the molecular genetics and evolutionary of , its complete plastid genome was sequenced and annotated. The assembled chloroplast genome is a circular 151,083 bp sequence, consisting of a 82,302 bp large single copy region (LSC) and a 17,449 bp small single copy region (SSC), which were flanked by a pair of 25,666 bp inverted repeats (IRs). The GC content of the chloroplast genome is 38.03%. Moreover, a total of 134 functional genes were annotated, including 88 protein-coding, 38 tRNA, and 8 rRNA genes. Phylogenetic analysis showed that has close relationship with Poi. The current study provides important information for further genetic studies on Plantaginacea.
婆婆纳属（车前科）是一种具有高药用价值的多年生草本植物。为了更好地了解其分子遗传学和进化情况，对其完整的叶绿体基因组进行了测序和注释。组装后的叶绿体基因组是一个151,083 bp的环状序列，由一个82,302 bp的大单拷贝区域（LSC）和一个17,449 bp的小单拷贝区域（SSC）组成，两侧是一对25,666 bp的反向重复序列（IRs）。叶绿体基因组的GC含量为38.03%。此外，总共注释了134个功能基因，包括88个蛋白质编码基因、38个tRNA基因和8个rRNA基因。系统发育分析表明，婆婆纳属与Poi.关系密切。目前的研究为车前科进一步的遗传学研究提供了重要信息。
