Abstract

Coelogyne fimbriata is an important orchid species with high medicinal value. Its complete chloroplast genome is 158,935 bp in length, which possesses the typical structure consising of a small single-copy region (SSC) of 18,743 bp, two inverted repeats (IRs) of 26,374 bp, and a large-single copy region (LSC) of 87,444 bp. The genome encodes 137 genes, including 91 protein-coding genes (PCGs), 38 tRNA genes and 8 rRNA genes. And the overall GC content is 37.40%. In addition, our phylogenetic analysis based on cp genome revealed the phylogenetic relationship between C. fimbriata and other 22 species in Orchidaceae.

摘要

Coelogyne fimbriata是重要的兰花品种，具有很高的药用价值。其完整的叶绿体基因组长度为158,935 bp，具有典型的结构，包括一个18,743 bp的小单拷贝区（SSC），两个26,374 bp的反向反向重复（IR）和一个大单拷贝区（LSC） 87444 bp。该基因组编码137个基因，包括91个蛋白质编码基因（PCG），38个tRNA基因和8个rRNA基因。GC的总含量为37.40％。此外，我们基于cp基因组的系统发育分析揭示了C. fimbriata与兰科的其他22种之间的系统发育关系。
