Hieron. is a morphologically distinctive species in the genus. It is identified by lanceolate pinnules with serrated margins, free veins, hydathodes extending into teeth, and laminae abaxially hairy. It is mainly distributed in the tropical and subtropical regions of Asia. Herein, we report the first complete chloroplast genome sequence of Also, it is the opening one of the genus Fée. The chloroplast genome sequence is 153,561 bp in length. The genome has a typical quadripartite structure, including a large single-copy (LSC) region of 82,817 bp, a small single-copy (SSC) region of 21,236 bp, and two inverted repeat (IR) regions of 24,754bp each. The total GC content is 45.0%. The complete plastome sequence contains 114 genes, including, 81 protein-coding, 29 tRNA, and four rRNA genes. The phylogenetic analysis of Pteridaceae based on the complete chloroplast genomes was also presented in this study.
希耶罗蕨是该属中形态独特的一个物种。它通过具锯齿状边缘的披针形羽片、游离脉、延伸至齿的排水器以及叶背有毛来识别。它主要分布在亚洲的热带和亚热带地区。在此，我们报道了希耶罗蕨的首个完整叶绿体基因组序列。此外，它是费氏蕨属的首个公开序列。叶绿体基因组序列长度为153,561 bp。该基因组具有典型的四分体结构，包括一个82,817 bp的大单拷贝（LSC）区域、一个21,236 bp的小单拷贝（SSC）区域以及两个各为24,754 bp的反向重复（IR）区域。总GC含量为45.0%。完整的质体基因组序列包含114个基因，包括81个蛋白质编码基因、29个tRNA基因和4个rRNA基因。本研究还基于完整叶绿体基因组对凤尾蕨科进行了系统发育分析。
