Characterization and phylogenetic analysis of the complete chloroplast genome of (L.) H. Rob.

is a member of the tribe Vernonieae from the family Compositae. The tribe was traditionally placed in the subfamily Cichorioideae, but is recently proposed to be placed in its own subfamily Vernonioideae. The complete chloroplast genome (cp genome) of the genus is sequenced for the first time. The cp genome of is 152,750 bp in length. It contained a large single copy (LSC) region (83,871 bp), and small single copy (SSC) region (18,487 bp), and two inverted repeats (IRs, 25,196 bp). Phylogenetic analysis of 20 species was conducted. and which are members of tribe Vernonieae nested outside of the monophyletic clade formed by members of subfamily Cichorioideae. The findings would be useful to understand the phylogeny of the genus and the subfamily Vernonioideae.
