Asplenium pseudocapillipes (Aspleniaceae), a New Fern Species from South Korea

The complete chloroplast genome of the neo-allotetraploid fern, Asplenium pseudocapillipes S.H.Park et al. (Aspleniaceae)

This study analyzed the complete plastome sequence of the neo-allotetraploid Asplenium pseudocapillipes S.H.Park et al. Asplenium pseudocapillipes has a typical circular plastome that comprises 157,242 bp with a large single copy (84,105 bp), a small single copy (21,503 bp), and two inverted repeats (IRs; 25,817 bp). The complete sequence comprises 127 genes, including 87 protein-coding genes (CDSs), eight ribosomal RNAs (rRNAs), 31 transfer RNAs (tRNAs), and one pseudogene. Among these genes, five CDSs, four rRNAs, and five tRNAs are duplicated in IRs. The guanine-cytosine content of the genome was 41.5%. The enlarged noncoding regions by Mobile Open Reading Frames in Fern Organelles were found once in other Asplenium species and twice in A. pseudocapillipes. Phylogenetic analysis based on 83 coding gene sequences revealed that A. pseudocapillipes is embedded in the A. varians subclade along with its progenitors.
