is an invasive aquatic weed in South China. In this study, the first complete chloroplast (cp) genome of was reported and phylogenetic analysis was conducted with Araceae species based on the cp genome sequences. The genome is a circular molecule of 164,551 bp in length with 36.00% average GC content and includes a large single-copy region (90,705 bp), a small single-copy region (21,886 bp), and two inverted repeat regions (25,980 bp). It contains a total of 129 genes, including 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The maximum likelihood tree indicated that is related to the genus of The cp genome will provide useful molecular data for further phylogenetic and evolutionary analysis of .
是中国南方的一种入侵性水生杂草。在本研究中，报道了该植物的首个完整叶绿体（cp）基因组，并基于cp基因组序列对天南星科物种进行了系统发育分析。该基因组是一个长度为164,551 bp的环状分子，平均GC含量为36.00%，包括一个大单拷贝区域（90,705 bp）、一个小单拷贝区域（21,886 bp）和两个反向重复区域（25,980 bp）。它总共包含129个基因，包括84个蛋白质编码基因、37个tRNA基因和8个rRNA基因。最大似然树表明该植物与某属相关。该cp基因组将为该植物进一步的系统发育和进化分析提供有用的分子数据。
