Hu et T. C. Huang, belonging to the Theaceae family, is an excellent landscape tree species with high ornamental value. It is also an important woody oil-bearing plant with high economic value. This study reports the first complete chloroplast genome sequence of (GenBank accession number: MZ054232). Its whole chloroplast genome is 156,953 bp long with an overall GC content of 37.31%, which is composed of a large single copy region (86,631 bp), a small single copy region (18,402 bp), and a pair of inverted repeat regions (25,960 bp each). A total of 135 genes were predicted in this genome, namely eight ribosomal RNA genes, 37 transfer RNA genes, and 90 protein-coding genes. Based on maximum likelihood analysis results, we found that the species are clustered into a distinct branch, and the phylogenetic relationships among , , and were the closest.
Hu和T. C. Huang属于山茶科，是具有高观赏价值的优良园林树种。它也是具有高经济价值的重要木本油料植物。本研究报道了（GenBank登录号：MZ054232）的首个完整叶绿体基因组序列。其完整叶绿体基因组长度为156,953 bp，总体GC含量为37.31%，由一个大单拷贝区域（86,631 bp）、一个小单拷贝区域（18,402 bp）和一对反向重复区域（各25,960 bp）组成。该基因组共预测到135个基因，即8个核糖体RNA基因、37个转运RNA基因和90个蛋白质编码基因。基于最大似然分析结果，我们发现该物种聚为一个独特的分支，且该物种与该物种、该物种之间的系统发育关系最为密切。
