Peucedanum hakuunense Nakai is one of the rare species in the Korean Peninsula. This study characterized the complete plastid genome (plastome) sequence of P. hakuunense by de novo assembly with next-generation sequencing data. The complete plastome of P. hakuunense is 147,426 bp in length with a typical quadripartite structure comprising a large single-copy region of 91,915 bp, a small single-copy region of 17,425 bp, and two inverted repeat regions of 19,043 bp in length. The plastome of P. hakuunense is composed of 85 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. The phylogenetic analysis revealed that two Peucedanum species formed an independent subclade, sister to the subclade of Angelica species within the tribe Selineae.

Liriope platyphylla is herbaceous perennial plant belonging to the Asparagaceae family and widely used both as ornamental plant and herbal medicine. The complete chloroplast genome of L. platyphylla was 156,754 bp in length, which was composed of four distinct parts; a large single copy (LSC) of 85,118 bp, a small single copy (SSC) of 18,680 bp, and a pair of inverted repeat regions (IRa and IRb) of 26,478 bp. A total of 130 genes including 83 protein-coding genes, 39 tRNA genes and 8 rRNA genes were identified. The phylogenetic tree showed that L. platyphylla has a close relationship with other Nolinoideae plants, especially with Maianthemum dilatatum and Nolina atopocarpa.

Wolfiporia cocos have been used as diuretic, sedative, and tonic medicine. Although its medicinal effects were reported, its genomic information is rare. In this paper, we report the complete mitochondrial genome of Wolfiporia cocos which is a 136,067 bp circular structure with 5 protein-coding genes, 25 tRNA genes, and 2 rRNA genes. Additional six protein-coding genes (cob, cox1, cox2, cox3, nad2, nad6) were truncated or pseudogenized by internal stop codons. Phylogenetic analysis of the mitochondrial genome of W. cocos showed the distinct relationship with other five mitochondrial genomes of Polyporales.

Rehmannia glutinosa is a plant used as traditional medicine for its various tonic effects in Korea and China. In this study, chloroplast genomes of two R. glutinosa were completed by de novo assembly using whole-genome Illumina sequence data. The length of chloroplast genomes of R. glutinosa collected from China and Korea was 153,680 bp and 153,499 bp, respectively. A total of 114 coding regions were predicted in both R. glutinosa including 80 protein-coding genes, 4 rRNA genes, and 30 tRNA genes. We identified abundant intra-species diversity of 87 InDels and 147 SNPs, among three R. glutinosa chloroplast genome sequences including one from GenBank. The phylogenetic analysis showed that these R. glutinosa were closely clustered with related Rehmannia species, separated from other Orobanchaceae and Scrophulariaceae species.

Lonicera japonica is a traditional medicinal plant well known for its anti-inflammatory effect. The complete chloroplast genome sequence of L. japonica collected from Korea was obtained by de novo assembly using whole genome sequence data. The chloroplast genome is 155,060 bp in length, containing 88,853 bp in a large single copy (LSC), 18,653 bp in a small single copy (SSC) and 23,777 bp in a pair of inverted repeats (IRs). A total of 112 genes including 78 protein-coding genes and 34 structural RNA genes were identified. The sequence comparison of two L. japonica collected from Korea and China revealed 48 single nucleotide polymorphisms (SNPs) and 45 insertions/deletions (InDels). In addition, phylogenetic analysis represented intraspecific diversity within L. japonica species collected in Korea and China.

Hosta capitata (Koidz.) Nakai is an herbaceous perennial plant belonging to the Asparagaceae family and has become a popular ornamental plant. In this study, the chloroplast genome sequence of H. capitata was completed by de novo assembly with whole genome sequence data. The chloroplast genome of H. capitata is 156,416 bp in length, which is composed of a large single-copy (LSC) of 84,788 bp, a small single-copy (SSC) of 18,206 bp, and a pair of inverted repeat regions (IRa and IRb) of 26,711 bp, as four distinct parts. In total, 114 genes were identified including 80 protein-coding genes, 30 tRNA genes, and four rRNA genes. The phylogenetic analysis revealed that H. capitata has a close relationship with other Hosta species, H. minor and H. ventricosa, but is farther than the distance between them.

Magic Lily (Lycoris squamigera), belonging to the Amaryllidaceae family, is cultivated for ornamental and medicinal purposes. To characterize its genomic information, we obtained the complete chloroplast genome sequence of L. squamigera by assembling Illumina whole genome sequence data. The complete chloroplast genome is 158,482 bp in length which is composed of four unique regions, a large single copy region (LSC) of 86,454 bp, a small single copy region (SSC) of 18,500 bp, and a pair of inverted repeats (IR) of 26,764 bp. The genome annotation predicted 159 genes including 105 protein-coding genes, 46 tRNA genes, and 8 rRNA genes. Phylogenetic tree analysis revealed that L. squamigera clustered with Allium species belonging to the Amaryllidaceae family.
