Abstract

Pseudostellaria davidii (Franch.) Pax belongs to subseries distancs of Pseudostellaria (Caryophyllaceae), and is mainly distributed in north-eastern Asia. The complete chloroplast (cp) genome of P. davidii was assembled and annotated for the first time in this study. The cp genome of P. davidii is 149,732 bp in length with the GC content of 36.57%, and it consists of four subregions: a large single-copy (LSC) region of 81,156 bp, a small single-copy (SSC) region of 16,894 bp and two inverted repeats (IR) regions of 25,841 bp each. The cp genome of P. davidii encodes a total of 111 unique genes, which are 77 protein-coding genes, four rRNA genes, and 30 tRNA genes. The results of phylogenetic analysis strongly suggested that Pseudostellaria was a monophyletic group and P. davidii forms an independent sister clade to other species of Pseudostellaria.
