Completed chloroplast genome of Campanula takesimana Nakai isolated from Dokdo island in Korea is 169,719 bp long (GC ratio is 38.8%) and has four subregions: 102,381 bp of large single-copy (37.8%) and 7,750 bp of small single-copy (32.6%) regions are separated by 29,794 bp of inverted repeat (41.3%) regions including 131 genes (87 protein-coding genes, eight rRNAs, and 36 tRNAs). Phylogenetic analyses suggested that C. takesimana from Dokdo Island form a clade with C. takesimana from Ulleungdo Island and that chloroplast genomes of the two accessions are diverged.

The complete chloroplast genome sequence of Lychnis kiusiana Makino (Caryophyllaceae) was determined. The genome was 151,831 bp long, consisting of a large single-copy region (83,875 bp) and a small single-copy region (17,591 bp) separated by two inverted repeats (25,331 bp). The plastome contained 124 genes; 82 encode proteins, 34 encode tRNA, and eight encode rRNA. The gene quantity and order resembled those of a typical Caryophyllaceae plastome. Phylogenetic analysis using 79 gene sequences from 14 previously reported genomes of Caryophyllaceae showed that Lychnis clades were nested within the Silene genus, suggesting that Lychnis is a lower taxonomic rank than genus.

The giant knotweed plant, Fallopia sachalinensis is confined to Ulleung and Dokdo islands, Korea. Here, we reported the complete chloroplast genome of F. sachalinensis. The chloroplast genome size was 163,485 bp in length, containing a couple of identical inverted repeat regions of 31,108 bp, a large single-copy region of 87,703 bp and small single-copy region of 13,566 bp. The genome encoded 129 genes, of which 112 were unique, including 78 protein-coding, 30 tRNA and 4 rRNA genes. The maximum-likelihood phylogenetic tree showed that F. sachalinensis is a basal group and sister to the rest of the Polygonaceae family plants.

The complete chloroplast genome sequence of Maianthemum dilatatum is sequenced and analyzed. The chloroplast genome is 156,921 bp, with 36.7% GC content. A pair of inverted repeats of 26,468 bp is separated by a large single-copy region (85,554 bp) and a small single-copy region (18,431 bp). It encodes 86 protein-coding genes, 38 tRNA genes and 8 rRNA genes. Of 132 individual genes, 19 genes are duplicated in the IR regions, while 14 genes are encoded with one intron and three genes with two introns.
