is naturally distributed in Southern China, which is an elite natural tree with high edible and medicinal value. In this study, whole chloroplast (cp) genome of was assembled and characterized on the basis of Illumina pair-end sequencing data. The complete cp genome was 156,417 bp in length, containing a large single-copy region (LSC) of 85,607 bp and a small single-copy region (SSC) of 18,164 bp, which were separated by a pair of 26,323 bp inverted repeat regions (IRs). The genome contained 128 genes, including 85 protein-coding genes, 35 tRNA genes, and 8 rRNA genes. The overall GC content is 36.32%, while the corresponding values of the LSC, SSC, and IR regions were 33.98, 29.45, and 42.48%, respectively. The maximum-likelihood phylogenetic analysis showed a strong sister relationship with . These findings provide a foundation for further investigation of cp genome evolution in and other higher plants.
自然分布于中国南方，是一种具有高食用和药用价值的优良天然树种。在本研究中，基于Illumina双末端测序数据组装并表征了该树种的完整叶绿体（cp）基因组。完整的cp基因组长度为156,417 bp，包含一个85,607 bp的大单拷贝区域（LSC）和一个18,164 bp的小单拷贝区域（SSC），它们被一对26,323 bp的反向重复区域（IR）隔开。该基因组包含128个基因，包括85个蛋白质编码基因、35个tRNA基因和8个rRNA基因。总体GC含量为36.32%，而LSC、SSC和IR区域的相应值分别为33.98%、29.45%和42.48%。最大似然系统发育分析显示与……有很强的姐妹关系。这些发现为进一步研究该树种及其他高等植物的cp基因组进化提供了基础。
