Burm. f. (1768) is an evergreen shrub native to New Guinea and the Bismarck Archipelago. Currently, it is widely cultivated as an ornamental and medicinal plant in tropical and subtropical areas worldwide. This study characterized the complete chloroplast genome of , which is 172,122 bp in length and consists of large single-copy (LSC) and small single-copy (SSC) regions of 97,025 bp and 19,787 bp, respectively, that are separated by a pair of 27,655 bp inverted repeat (IR) regions. The overall GC content of the genome is 34.22%. The genome contains 131 genes, including 86 protein-coding, 37 tRNA, and eight rRNA genes. Phylogenetic analysis indicates that is closely related to and in the Euphorbiaceae family. The complete chloroplast genome of provides genomic resources and potential markers suitable for future species identification and speciation studies of the genus and will also provide important information on the phylogenetic relationships of the Euphorbiaceae family.
Burm. f.（1768 年）是一种原产于新几内亚和俾斯麦群岛的常绿灌木。目前，它作为观赏植物和药用植物在全球热带和亚热带地区广泛种植。本研究对[植物名称]的完整叶绿体基因组进行了特征分析，其长度为 172,122 碱基对，由长度分别为 97,025 碱基对的大单拷贝（LSC）区域和 19,787 碱基对的小单拷贝（SSC）区域组成，这两个区域被一对 27,655 碱基对的反向重复（IR）区域隔开。基因组的总体 GC 含量为 34.22%。该基因组包含 131 个基因，包括 86 个蛋白质编码基因、37 个 tRNA 基因和 8 个 rRNA 基因。系统发育分析表明，[植物名称]与大戟科的[其他植物名称]和[其他植物名称]密切相关。[植物名称]的完整叶绿体基因组提供了适合未来该属物种鉴定和物种形成研究的基因组资源和潜在标记，也将为大戟科的系统发育关系提供重要信息。
