Abstract
The complete chloroplast genomes from two sister species of Pugionium Gaertn are determined in this study. The genome sizes were 155,002 bp (Pugionium dolabratum) and 154,992 bp (Pugionium cornutum). Both genomes containing a large single copy region of 84 k bp and a small single copy region of 18 k bp, which were separated by a pair of 26,761 bp inverted repeat regions. The cpDNA contained 128 genes, including 83 protein-coding genes (76 PCG species), 37 tRNA genes (30 tRNA species) and eight ribosomal RNA genes (four rRNA species). The most of gene species occur as a single copy, while 18 gene species occur in double copies. These complete chloroplast genomes can be subsequently used for population genomic studies of Pugionium, and provide valuable insight into conservation and restoration efforts for this endangered species.
