The complete chloroplast genome of , a rare species in the family Orchidaceae was reported in this study. The genome size is 175,122 bp in length, and contains four sub-regions: 97,486 bp of large single copy (LSC) and 22,260 bp of small copy (SSC) regions, separated by 27,688 bp of inverted repeat (IR) regions. A total of 133 genes were annotated, including 87 protein-coding genes, 38 tRNA genes and 8 rRNA genes. The GC content of this cp genome is 34.36%. Phylogenetic analysis revealed a close relationship between with and . This is the first complete cp genome for that would be useful for conservation and phylogenetic studies of this species.
本研究报道了兰科一种珍稀物种的完整叶绿体基因组。该基因组长度为175,122 bp，包含四个亚区域：97,486 bp的大单拷贝（LSC）区域和22,260 bp的小单拷贝（SSC）区域，由27,688 bp的反向重复（IR）区域隔开。共注释了133个基因，包括87个蛋白质编码基因、38个tRNA基因和8个rRNA基因。该叶绿体基因组的GC含量为34.36%。系统发育分析表明，[物种名称1]与[物种名称2]和[物种名称3]之间关系密切。这是[物种名称1]的首个完整叶绿体基因组，将有助于该物种的保护和系统发育研究。
