is widely distributed submerged macrophyte in the world. Herein, the complete chloroplast genome of this species was assembled and characterized using whole genome next-generation sequencing. The complete chloroplast genome showed a circular genome of 156,669 bp size with 36.5% GC content. The genome is of typical structure and contain a pair of inverted repeat (IR) regions with 26,074 bp, separated by one large single-copy (LSC) with 86,285 bp, and one small single-copy (SSC) regions with 18,236 bp. assembly and annotation showed the presence of 131 unique genes with 85 protein-coding genes, 38 tRNA genes, and eight rRNA genes. A maximum-likelihood phylogenomic tree reconstructed based on 15 chloroplast genomes reveals that is most closely related to
是世界上广泛分布的沉水植物。在此，利用全基因组二代测序技术组装并鉴定了该物种的完整叶绿体基因组。完整的叶绿体基因组呈环状，大小为156,669 bp，GC含量为36.5%。该基因组结构典型，包含一对26,074 bp的反向重复（IR）区域，被一个86,285 bp的大单拷贝（LSC）区域和一个18,236 bp的小单拷贝（SSC）区域隔开。组装和注释显示存在131个独特基因，包括85个蛋白质编码基因、38个tRNA基因和8个rRNA基因。基于15个叶绿体基因组重建的最大似然系统发育树表明， 与 关系最为密切。
