The complete chloroplast genome sequence of coastal psammophyte, Ixeris repens (Asteraceae, subtribe Crepidinae), in Korea.
We report the first complete chloroplast genome sequence of psammophyte, Ixeris repens, on the coastal dunes in Korea. The complete plastid genome is 153,017 bp in total length, with one large single copy (LSC; 84,242 bp), one small single copy (SSC; 18,495 bp), and two inverted repeat (IR) regions (IRa and IRb, each with 25,140 bp). The overall GC content is 37.6% and the genome contains 130 genes, including 85 protein-coding, 37 transfer RNA and 8 ribosomal RNA genes. Phylogenetic analysis based on 17 representative plastomes of the family Asteraceae suggests that Ixeris repens is sister to congeneric species I. polycephala with strong bootstrap support (100%) and also that monophyletic Ixeris is sister to the clade containing Taraxacum, Youngia, Lapsanastrum, and Crepidiastrum.
