The complete chloroplast genome of Dryopteris crassirhizoma Nakai

Dryopteris crassirhizoma Nakai is a fern plant with important evolutionary and medicinal values. Herein, we assembled the complete chloroplast genome of D. crassirhizoma by next-generation sequencing technology. The complete chloroplast genome of D. crassirhizoma 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 D. crassirhizoma and D. decipiens from Dryopteridaceae were most closely related to Lepisorus clathratus from Polypodiaceae.

Automated summary

The complete chloroplast genome of Dryopteris crassirhizoma Nakai was assembled and analyzed, revealing its genetic composition and evolutionary relationships, particularly its close relation to Lepisorus clathratus from the Polypodiaceae family.
