Abstract
The Korean endemic Eranthis byunsanensis B.Y. Sun, 1993 (Ranunculaceae) is a rare plant distributed in the southwestern part of the Korean Peninsula. The complete chloroplast (cp) genome of E. byunsanensis was sequenced by next-generation sequencing (NGS) using an Illumina HiSeq X platform. The cp genome of E. byunsanensis is 160,324 bp in length with 37.9% GC content. It showed a typical quadripartite structure consisting of a pair of inverted repeats (IRs; 28,356 bp), a large single-copy region (LSC; 87,671 bp), and a small single-copy region (SSC; 15,941 bp). The cp genome comprises 130 genes including 85 protein-coding genes (PCGs), 37 tRNA genes, and eight rRNA genes. The molecular phylogenetic analysis indicates that E. byunsanensis is closely related to Eranthis stellata, both of which belong to the genus Eranthis.
