We presented complete chloroplast genome of Prince Ginseng, Pseudostellaria heterophylla which is 149,795 bp long and has four subregions: 81,460 bp of large single copy (LSC) and 16,983 bp of small single copy (SSC) regions are separated by 25,676 bp of inverted repeat (IR) regions including 126 genes (81 CDS, 8 rRNAs, and 37 tRNAs). The overall GC content of the chloroplast genome is 36.5% and those in the LSC, SSC, and IR regions are 34.3%, 29.4%, and 42.3%, respectively. Phylogenetic trees of 25 Caryophyllaceae species present phylogenetic position of P. heterophylla among available Pseudostellaria species.

Pseudostellaria palibiniana which belongs to subseries Verticilatae is one of the species in Pseudostellaria palibiniana species complex (PPSC). To uncover intraspecies variation of P. palibiniana, we presented its second complete chloroplast genome which is 149,639 bp long and has four subregions: 81,286 bp of large single copy and 16,977 bp of small single copy regions are separated by 25,688 bp of inverted repeat regions including 126 genes (81 protein-coding genes, 8 rRNAs, and 37 tRNAs). The overall GC content is 36.5% and those in the LSC, SSC, and IR regions are 34.3%, 29.4%, and 42.4%, respectively. Eighty-four single nucleotide polymorphisms and 125 insertions and deletions are identified between two individuals of P. palibiniana. Phylogenetic tree presents that P. palibiniana isolated from the same place of Pseudostellaria longipedicellata is clustered with another P. palibiniana, showing that PPSC can be solved using complete chloroplast genomes. © 2019, © 2019 The Author(s).

Pseudostellaria palibiniana (Takeda) Ohwi which belongs to Caryophyllaceae is distributed in Korea and Japan. In this study, we present the complete chloroplast genome of P. palibiniana which is 149,668 bp long and has four subregions: 81,313 bp of large single copy (LSC) and 16,958 bp of small single copy (SSC) regions are separated by 25,709 bp of inverted repeat (IR) regions including 126 genes (81 protein-coding genes, eight rRNAs, and 37 tRNAs). The overall GC content of the chloroplast genome is 36.5% and those in the LSC, SSC, and IR regions are 34.3%, 29.4%, and 42.4%, respectively.
Pseudostellaria okamotoi Ohwi is the endemic species with limited habitat which is subalpine area in central Southern part of the Korean peninsula. In this study, we presented the complete chloroplast genome of P. okamotoi of which length is 149,611 bp. It consists of four subregions: 81,291 bp of large single copy (LSC) and 16,958 bp of small single copy (SSC) regions are separated by 25,681 bp of inverted repeat (IRs) regions. It includes 126 genes (81 coding genes, eight rRNAs, and 37 tRNAs). The overall GC contents of the chloroplast genome were 36.5% and in the LSC, SSC and IR regions were 35.3%, 29.3%, and 42.4%, respectively.
Pseudostellaria longipedicellata which belongs to Caryophyllaceae is endemic in South Korea. In this study, we presented first complete chloroplast genome of P. longipedicellata which is 149,626 bp and has four sub-regions: 81,292 bp of large single copy (LSC) and 16,984 bp of small single copy (SSC) regions are separated by 25,675 bp of inverted repeat (IRs) regions including 126 genes (81 CDS, eight rRNAs, and 37 tRNAs). The overall GC contents of the chloroplast genome were 36.5% and in the LSC, SSC and IR regions were 34.3%, 29.3%, and 42.4%, respectively.
