Complete chloroplast genome of Plantago asiatica and its phylogenetic position in Plantaginaceae

Abstract

Plantago asiatica, an herbaceous perennial species of Plantaginaceae, has been used as a traditional herbal medicine plant in China. In this study, the complete chloroplast (cp) genome of P. asiatica was sequenced and assembled using genome skimming data. The cp genome was 165,045 bp in length including the large single-copy (LSC, 82,964 bp) and small single-copy (SSC, 4,633 bp) regions separated by two copies of inverted region (IR, 38,724 bp). The cp genome encoded 113 unique genes, consisting of 79 protein-coding genes, 30 tRNA genes, and four rRNA genes, additionally with 27 duplicated genes in the IR regions. Phylogenetic analysis indicated that the representative species from Plantago was monophyletic and they were divided into four subgenera. P. asiatica belongs to the subgenus Plantago and was sister to P. rigida with high bootstrap value support.
