This study presents the chloroplast genome of (L.) Less, Asteraceae, one wide distributed species of mangrove associates plant in China, which was assembled and analyzed by de novo assembly using whole-genome sequencing data. The accessing NC_015621 was used as a reference sequence in this study. The size of the complete chloroplast genome was found to be 152,298 bp in length, comprising a large single copy region (LSC) of 84,127bp, a small single copy region (SSC) 18,068 bp, and inverted repeat regions (IRS) of 25,051bp. A total of 128 genes, including 84 protein-coding genes, 36 tRNA genes and eight rRNA genes, were predicted from the chloroplast genomes. Among them, 17 genes occur in IRS, containing six protein-coding genes, seven tRNA genes and four rRNA genes. The GC content of is 37.49%. The phylogenetic analysis with four Asterids species and five other species revealed that was clusted with .
本研究展示了菊科（L.）Less.的叶绿体基因组，这是中国一种广泛分布的红树林伴生植物，其叶绿体基因组通过使用全基因组测序数据进行从头组装而得以组装和分析。本研究中使用登录号为NC_015621的序列作为参考序列。完整叶绿体基因组的长度为152,298 bp，包括一个84,127 bp的大单拷贝区域（LSC）、一个18,068 bp的小单拷贝区域（SSC）和25,051 bp的反向重复区域（IRS）。从叶绿体基因组中预测出总共128个基因，包括84个蛋白质编码基因、36个tRNA基因和8个rRNA基因。其中，17个基因存在于IRS中，包括6个蛋白质编码基因、7个tRNA基因和4个rRNA基因。该叶绿体基因组的GC含量为37.49%。与4种菊类植物和其他5个物种进行的系统发育分析表明，（此处原文缺失相关植物名称）与（此处原文缺失相关植物名称）聚类在一起。
