is a kind of tertiary paleotropical plant floristic relic species unique to China. This rare plant is disappearing due to poor adaptability and serious poaching. has been listed as a national first-level protected wild plant, a unique genus plant unique to China, a relic plant, and a well-known ornamental plant in the world. It is a national-level protected plant. In this study, the complete chloroplast genome sequence of was characterized from Illumina pair-end sequencing. The chloroplast genome of was 158,118 bp in length, containing a large single-copy (LSC) region of 87,329 bp, a small single-copy (SSC) region of 18,869 bp, and two inverted repeat (IR) regions of 25,960 bp. The overall GC content is 37.80%, while the corresponding values of the LSC, SSC, and IR regions are 36.0%, 31.6%, and 43.1%, respectively. The genome contains 132 complete genes, including 86 protein-coding genes, 38 tRNA genes, and eight rRNA genes. Phylogenetic analysis based on complete chloroplast genomes showed that and clustered together as sisters to other related species.
是中国特有的一种第三纪古热带植物区系残遗物种。这种珍稀植物由于适应性差和盗猎严重正在消失。已被列为国家一级保护野生植物，是中国特有的单属植物、残遗植物和世界著名的观赏植物。它是国家级保护植物。在本研究中，通过Illumina双端测序对其完整叶绿体基因组序列进行了表征。其叶绿体基因组长度为158,118 bp，包含一个87,329 bp的大单拷贝（LSC）区域、一个18,869 bp的小单拷贝（SSC）区域和两个25,960 bp的反向重复（IR）区域。总体GC含量为37.80%，而LSC、SSC和IR区域的相应值分别为36.0%、31.6%和43.1%。该基因组包含132个完整基因，包括86个蛋白质编码基因、38个tRNA基因和8个rRNA基因。基于完整叶绿体基因组的系统发育分析表明，与其他相关物种聚在一起，形成姐妹关系。
