Abstract

Cyrtosia nana is a mycotrophic orchid distributed in southwestern China and Thailand. Here, we sequenced and assembled its complete chloroplast (cp) genome using next-generation sequencing (NGS) and established a robust phylogenetic framework, providing a foundation for further studies on evolution of related taxa. The complete chloroplast genome was 85,766 bp, including a pair of inverted repeat regions (12,999 bp), a small single-copy region (14,744 bp), and a large single-copy region (45,024 bp). It encodes 47 unique genes, including 28 protein-coding genes, 16 tRNA genes, and 3 rRNA genes. Phylogenetic analysis revealed that C. nana was closely related to C. lindleyana and C. septentrionalis.

文章作者：苏兰（Cyrtosia nana, Rolfe ex Downie） Garay)叶绿体全基因组及其系统发育分析。

小兰是一种真菌性兰花，分布在中国西南部和泰国。本研究利用新一代测序技术（NGS）对其叶绿体（cp）全基因组进行了测序和组装，建立了完整的系统发育框架，为进一步研究相关类群的进化奠定了基础。叶绿体基因组全长85,766 bp，包括一对反向重复区（12,999 bp）、一个小的单拷贝区（14,744 bp）和一个大的单拷贝区（45,024 bp）。它编码47个独特的基因，包括28个蛋白质编码基因、16个tRNA基因和3个rRNA基因。系统发育分析表明，奈那氏c与林氏c和七氏c亲缘关系较近。
