Characterization and phylogenetic analysis of the complete chloroplast genome of Emilia sonchifolia (L.) DC.

Abstract

Emilia sonchifolia is a herb with antioxidant, anti-inflammatory, antitumor, and wound healing properties. The complete chloroplast genome (cp genome) of the genus Emilia was sequenced for the first time. The cp genome of E. sonchifolia is 151,474 bp in length. It contained a large single-copy (LSC) region (84,004 bp), and small single-copy (SSC) region (17,980 bp), and two inverted repeats (IRs, 24,745 bp). Phylogenetic analysis of 24 species was conducted. E. sonchifolia was found to be closely related to Pericallis hybrida and Dendrosenecio spp. The sequenced cp genome would be useful to understand the phylogeny and genomic studies of the genus Emilia.
