Abstract

Artemisia borotalensis Poljakov is an endemic and endangered herb in China. In this study, we sequenced and analyzed the complete chloroplast genome of this species. Sequencing revealed the genome to be 151,179 bp in length, containing a large single copy region (82,862 bp), a small single copy region (18,377 bp), and a pair of inverted repeat regions (24,970 bp each). Our analyses demonstrated that it contained 133 genes, including 87 protein-coding genes, 37 transfer RNA genes, eight ribosomal RNA genes, and one pseudogene (ycf1). Furthermore, we found the genome to have an overall GC content of 37.4%. A phylogenetic analysis indicated that A. borotalensis and A. maritima clustered together as sister group to A. annua and A. fukudo clade.

Keywords: Artemisia borotalensis; Asteraceae; complete chloroplast genome; phylogenetic analysis.
