Abstract
Spergularia marina (L.) Griseb, 1843 (Caryophyllaceae) is a halophytic plant widely distributed along the southwestern coast of the Korean Peninsula. In this study, the complete chloroplast genome sequence of S. marina was determined using next-generation sequencing (NGS). The chloroplast genome of S. marina is 152,460 bp in length with 36.7% GC content. It comprises a large single-copy (LSC; 83,321), a small single copy (SSC; 17,205 bp), and a pair of inverted repeats (IRs; 25,967 bp) with a typical quadripartite structure. It consists of 131 genes, including 86 protein-coding genes, 8 ribosomal RNAs, and 37 transfer RNAs. Phylogenetic analysis using complete chloroplast genomes showed that among the 17 Caryophyllaceae species, S. marina is most closely related to Spergula arvensis. Since no complete chloroplast genome of the genus Spergularia has been reported to date, our study provides useful genetic information for determining phylogenetic relationships within the Caryophyllaceae.
