The complete chloroplast genome of Nakai.

Nakai is a fern plant with important evolutionary and medicinal values. Herein, we assembled the complete chloroplast genome of by next-generation sequencing technology. The complete chloroplast genome of was 153,355 bp in length, and the GC content was 42.86%; the genome consisted of a pair of inverted repeats (IRs, 23,470 bp), a small single copy region (SSC, 21,570 bp) and a large single copy region (LSC, 84,854 bp). The genome contained 111 genes, namely, 73 protein-coding genes, 34 tRNA genes and four rRNA genes. The phylogenetic analysis suggested that both and from Dryopteridaceae were most closely related to from Polypodiaceae.
