Illumina sequencing was employed to determine the complete chloroplast (cp) genome sequence of (), which is a relict fern. The cp genome of is indeed a circular DNA molecule with 156,659 bp. It includes an inverted repeats (IRs) pair with 24,011 bp each and two single-copy regions with 86,196 bp and 22,441 bp, respectively. Additionally, the genome contains 117 unique genes encoding 85 proteins, 28 tRNAs, four rRNAs. Pseudogenes of ycf66 and trnT-UGU are also detected in this genome.Bayesian phylogenetic tree strongly supports the deduction that belongs to Cyatheaceae. To date, this is the first cp genome for the genus
采用Illumina测序技术测定了一种残遗蕨类植物（）的完整叶绿体（cp）基因组序列。该植物的cp基因组确实是一个环状DNA分子，大小为156,659 bp。它包括一对各为24,011 bp的反向重复序列（IRs）以及两个分别为86,196 bp和22,441 bp的单拷贝区域。此外，该基因组包含117个独特基因，编码85种蛋白质、28个tRNA、4个rRNA。在这个基因组中还检测到了ycf66和trnT-UGU的假基因。贝叶斯系统发育树有力地支持了该植物属于桫椤科的推断。迄今为止，这是该属的首个cp基因组。
