Complete Genome Sequences of Crepidiastrum denticulatum (Asteraceae)

The genus Crepidiastrum (Asteraceae), containing ca. 20 species, is mainly distributed in Asia. Crepidiastrum denticulatum, an edible plant that commonly call "e-go-deulppae-gi" in Korean, distributes in Korea, Japan, and China. The complete chloroplast (cp) genome sequences of C. denticulatum was characterized from MiSeq2000 (Illumina Co.) pair-end sequencing data. The cp genome of C. denticulatum has a total sequence length of 152,689 bp and show a typical quadripartite structure. It consists of the large single copy (LSC: 84,022 bp), small single copy (SSC: 18,519 bp), separated by a pair of inverted repeats (IRs: 25,074 bp) and contains 110 unique genes and 18 genes duplicated in the IR regions. Our comparative analysis identified three cpDNA regions (matK, rbcL, and psbA-trnH) from three Crepidiastrum species, which may be useful for molecular identification of each species, and providing a guideline for its clear confirming about dried medical herb.
