Characterization of the complete chloroplast genome sequence of the giant knotweed, from the volcanic island Dokdo, Republic of Korea.

The giant knotweed plant, is confined to Ulleung and Dokdo islands, Korea. Here, we reported the complete chloroplast genome of . 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.
