The complete chloroplast genome sequence of the endemic and rare orchid Nothodoritis zhejiangensis (Orchidaceae) in China

Nothodoritis zhejiangensis (Orchidaceae) is a rare orchid unique to China of great horticultural value. The complete chloroplast genome of this species is 143,522 bp in length and the total GC content is 36.8%. It includes a large single copy (LSC) region of 83,830 bp in length, a small single copy (SSC) region of 10,764 bp and a pair of inverted repeat regions (IRs) with 24,464 bp. The chloroplast genome contains 120 functional genes, including 74 protein-coding genes, 38 tRNA genes and 8 rRNA genes. The phylogenetic tree constructed by the maximum-likelihood method showed that the taxonomic status of N. zhejiangensis was clustered with the species in Phalaenopsis.

浙江拟蝶唇兰（Nothodoritis zhejiangensis）隶属于兰科（Orchidaceae），是中国特有的珍稀兰科植物，具有重要的园艺价值。该物种的完整叶绿体基因组（chloroplast genome）全长为143522 bp，总GC含量为36.8%。其叶绿体基因组包含一个长83830 bp的大单拷贝区（large single copy, LSC）、一个长10764 bp的小单拷贝区（small single copy, SSC）以及一对长度为24464 bp的反向重复区（inverted repeat regions, IRs）。该叶绿体基因组共包含120个功能基因，其中包括74个蛋白质编码基因、38个转运RNA（transfer RNA, tRNA）基因以及8个核糖体RNA（ribosomal RNA, rRNA）基因。基于最大似然法（maximum-likelihood method）构建的系统发育树显示，浙江拟蝶唇兰的分类地位与蝴蝶兰属（Phalaenopsis）物种聚为一支。
