The first complete chloroplast genome of the fern genus Polystichum (Dryopteridaceae).

ABSTRACT: The first chloroplast genome of the fern genus Polystichum Roth (Dryopteridaceae) is reported here. Polystichum deltodon (Baker) Diels belongs to subgenus Haplopolystichum (Polystichum; Dryopteridaceae), many species of which are endangered or critically endangered species. The complete chloroplast genome of P. deltodon was determined for the first time in this work, which is revealed a circle quadripartite structure of 154,143 bp in length comprising a large single-copy region (LSC) of 86,990 bp, a small single-copy region (SSC) of 21,593 bp and a pair of inverted regions (IRs) of 22,780 bp, respectively. Based on the reported chloroplast genomes of Dryopteridaceae, phylogenetic analyses suggested that P. deltodon was located nearly to the genus <
