Abstract
The first complete chloroplast genome sequences of Korean endemic Epilobium in Ulleung Island, Epilobium ulleungensis, were reported in this study. The E. ulleungensis plastome was 160,912 bp long, with the large single copy (LSC) region of 88,915 bp, the small single copy (SSC) region of 17,327 bp, and two inverted repeat (IR) regions of 27,335 bp. The plastome contained 131 genes, including 84 protein-coding, eight ribosomal RNA, and 37 transfer RNA genes. The overall GC content was 36.5%. Phylogenetic analysis of nine representative plastomes within the family Onagraceae suggests strongly that E. ulleungensis is sister to the clade containing species of Oenothera in tribe Onagreae.
Highlights
Owing to its remarkable diversity in morphology, ecology, and cytology, the genus Epilobium L., with approximately 175 species, represents the largest group in Onagraceae and is mainly distributed in temperate regions (Raven 1988; Hoch and Raven 1992; Baum et al 1994)
Preliminary nrDNA ITS phylogeny within the genus was performed and infrageneric classification system was evaluated (Baum et al 1994), several questions require additional study based on extensive sampling within the genus and additional plastid and independent nuclear markers
Neither phylogenetic relationships nor complete chloroplast genome sequences is available among species of Epilobium in Korea
Summary
Owing to its remarkable diversity in morphology, ecology, and cytology, the genus Epilobium L., with approximately 175 species, represents the largest group in Onagraceae and is mainly distributed in temperate regions (Raven 1988; Hoch and Raven 1992; Baum et al 1994). KEYWORDS Chloroplast genome; Korean endemic; Epilobium ulleungensis; Ulleung Island; Onagraceae As for infrageneric classification system, eight highly distinctive sections have been proposed and recent molecular phylogenetic study recognized two main clades, i.e. sect.
