L. is an annual aquatic or marsh plant, wide spread in temperate regions throughout the world. In present study, we sequenced, assembled and annotated the complete chloroplast (cp) genome of . The length of complete cp genome was 150,138 bp, with a typical quadripartite structure comprising a pair of inverted repeat regions (IRs; 25,667 bp), a large single copy region (LSC; 81,432 bp) and a small single copy region (SSC; 17,372 bp). The whole cp genome contained 134 genes, including 89 protein-coding genes (PCGs), 37 transfer RNA (tRNA) genes, and eight ribosomal RNA (rRNA) genes. The maximum likelihood (ML) phylogenetic analysis indicated that was a member of Plantaginaceae, but the relationships between subfamilies and tribes need more samplings. This cp genome would provide a valuable genetic resource for ' phylogenetic study.
L.是一种一年生水生或沼泽植物，广泛分布于世界各地的温带地区。在本研究中，我们对L.的完整叶绿体（cp）基因组进行了测序、组装和注释。完整cp基因组的长度为150,138 bp，具有典型的四分体结构，包括一对反向重复区域（IRs；25,667 bp）、一个大单拷贝区域（LSC；81,432 bp）和一个小单拷贝区域（SSC；17,372 bp）。整个cp基因组包含134个基因，包括89个蛋白质编码基因（PCGs）、37个转运RNA（tRNA）基因和8个核糖体RNA（rRNA）基因。最大似然（ML）系统发育分析表明，L.是车前科的一员，但亚科和族之间的关系需要更多的样本。这个cp基因组将为L.的系统发育研究提供有价值的遗传资源。
