In this study, the complete chloroplast genome of the medical fern was completed and analyzed in order to understand the evolution of the genome of the fern lineages. In , the circular double-stranded cpDNA sequence of 154,305 bp consists of two inverted repeat (IRA and IRB) regions of 23,416 bp each, a large single-copy (LSC) region of 86,040 bp and a small single-copy (SSC) region of 21,433 bp. The overall GC content is 40.92% and the GC contents of LSC, IRs, and SSC are 39.75%, 45.07%, and 36.60%, respectively. with 108 annotated unique genes included 85 protein-coding genes, 19 tRNA genes, and 4 rRNA genes. Using the whole chloroplast genome sequences alignment of 18 species from ferns, the phylogenetic relationship was built. The phylogenetic position of was closely clustered with , and subsp as sister species and then clustered with , , , and . belongs to . The complete chloroplast genome of provides utility information for ferns evolutionary and genomic studies.
在本研究中，为了解蕨类谱系基因组的进化，完成并分析了药用蕨类植物的完整叶绿体基因组。其环状双链cpDNA序列长度为154,305 bp，由两个各为23,416 bp的反向重复序列（IRA和IRB）区域、一个86,040 bp的大单拷贝（LSC）区域和一个21,433 bp的小单拷贝（SSC）区域组成。总体GC含量为40.92%，LSC、IRs和SSC的GC含量分别为39.75%、45.07%和36.60%。该基因组有108个注释的独特基因，包括85个蛋白质编码基因、19个tRNA基因和4个rRNA基因。利用来自蕨类植物的18个物种的完整叶绿体基因组序列比对构建了系统发育关系。该植物的系统发育位置与[物种名1]、[物种名2]和[物种名3]亚种紧密聚类为姐妹种，然后与[物种名4]、[物种名5]、[物种名6]和[物种名7]聚类。该植物属于[所属类别]。该药用蕨类植物的完整叶绿体基因组为蕨类植物的进化和基因组研究提供了有用信息。
