Abstract

Panisea was a small genus in Orchidaceae including 12 species, while its generic relationships had been unclear. Here, we report the complete chloroplast (cp) genome sequence and the features of Panisea uniflora to provide molecular data for further systematic research. This complete cp genome was 159,341 bp in length and presented a typical quadripartite structure including one large single-copy region (LSC, 87,166 bp), one small single-copy region (SSC, 18,781 bp), and two inverted repeat regions (IR, 26,697 bp, each). The cp genome encoded 132 genes, of which 113 were unique genes. Besides, a maximum-likelihood phylogenetic analysis indicated that P. uniflora was mostly related to Pholidota imbricata in tribe Arethuseae.

摘要

Panisea是兰科的一个小属，包括12种，但其通用关系尚不清楚。在这里，我们报告完整的叶绿体（cp）基因组序列和独生的Panisea uniflora的特征，为进一步的系统研究提供分子数据。这个完整的cp基因组长度为159,341 bp，呈现出典型的四方结构，包括一个大的单拷贝区域（LSC，87,166 bp），一个小的单拷贝区域（SSC，18,781 bp）和两个反向重复区域（IR，每个26,697 bp）。cp基因组编码132个基因，其中113个是独特基因。此外，最大似然系统发育分析表明，斑节菊科与斑节菌（Pholidota imbricata）密切相关。
