is an economic species for its seeds with high oil content and ornamental value, which is cultivated widespreadly across southern China. In this study, the complete chloroplast (cp) genome sequence of was assembled and annotated in order to future genetic research. The whole cp genome of is 159,281 bp in size, composed of a small single copy (SSC) region of 15,662 bp and a large single copy (LSC) region of 86,251 bp separated by a pair of inverted repeats (IRs, IRA: 130598: 159281, IRB: 86252: 114935). The overall GC content of cp genome is 37.19%, with the base content A (31.03%), T (31.78%), C (18.94%), and G (18.25%). Phylogenetic analysis of 20 species based on 74 protein-coding genes shows that is evolutionarily closest to .
因其种子含油量高且具有观赏价值，是一种经济作物，在中国南方广泛种植。在本研究中，为了未来的遗传研究，对其完整的叶绿体（cp）基因组序列进行了组装和注释。其完整的叶绿体基因组大小为159,281 bp，由一个15,662 bp的小单拷贝（SSC）区域和一个86,251 bp的大单拷贝（LSC）区域组成，这两个区域被一对反向重复序列（IRs，IRA：130598：159281，IRB：86252：114935）隔开。其叶绿体基因组的总体GC含量为37.19%，碱基含量分别为A（31.03%）、T（31.78%）、C（18.94%）和G（18.25%）。基于74个蛋白质编码基因对20个物种进行的系统发育分析表明，其在进化上与最接近。
