Merr, a member of the genus in the family Rubiaceae, possesses significant medicinal and ornamental value and is widely distributed in China. This study reports the newly sequenced chloroplast genome of Merr. The complete chloroplast genome of Merr (155,109 bp, GC content of 37.5%) was shown to have a typical quadripartite structure, containing a pair of inverted repeat regions (IRs) of 28,802 bp separated by a large single-copy (LSC) region of 85,396 bp and a small single-copy (SSC) region of 18,109 bp. The chloroplast genome contained 151 genes encoding 106 proteins, 37 tRNAs, and eight rRNAs. The Merr chloroplast genome displayed the closest phylogenetic relationship to and var. grandiflora. These data will assist in future molecular phylogenetics of the Rubiaceae.
水锦树属茜草科成员，具有重要的药用和观赏价值，在中国广泛分布。本研究报道了水锦树新测序的叶绿体基因组。水锦树的完整叶绿体基因组（155,109 bp，GC含量为37.5%）显示具有典型的四分体结构，包含一对28,802 bp的反向重复区域（IRs），由一个85,396 bp的大单拷贝（LSC）区域和一个18,109 bp的小单拷贝（SSC）区域隔开。叶绿体基因组包含151个基因，编码106种蛋白质、37种tRNA和8种rRNA。水锦树叶绿体基因组与 和 变种大花水锦树显示出最密切的系统发育关系。这些数据将有助于茜草科未来的分子系统发育研究。
