The first complete chloroplast (cp) genome sequences of an endemic and endangered species in China, , were reported in this study. The cp genome of was 158,256 bp long, with two inverted repeat (IR) regions of 26,348 bp, a large single copy (LSC) region of 87,137 bp, and a small single copy (SSC) region of 18,423 bp. The cp genome of this species contained 113 genes, including 79 protein-coding genes, 4 ribosomal RNA genes, and 30 transfer RNA genes. The overall GC content was 36.7%. Phylogenetic analysis of 60 cp genomes within the subfamily of Epidendroideae suggests that is closely related to .
本研究报道了中国一种特有濒危物种的首个完整叶绿体(cp)基因组序列。该物种的cp基因组长度为158,256 bp,有两个26,348 bp的反向重复(IR)区域、一个87,137 bp的大单拷贝(LSC)区域和一个18,423 bp的小单拷贝(SSC)区域。该物种的cp基因组包含113个基因,其中包括79个蛋白质编码基因、4个核糖体RNA基因和30个转运RNA基因。总体GC含量为36.7%。对树兰亚科内60个cp基因组的系统发育分析表明,该物种与[另一物种名称]密切相关。
