The complete chloroplast genome of Hippuris vulgaris (Plantaginaceae).

Hippuris vulgaris is an aquatic perennial herb distributed worldwide. In this research, the complete chloroplast genome of H. vulgaris was sequenced and assembled. Its complete genome size was 152,698 bp in length. The typical quadripartite structure was shown, which contained a large single-copy region (82,940 bp), a small single-copy region (18,262 bp), and a pair of inverted repeat regions (25,748 bp). The CG content of this genome was 37.6%. A total of 114 genes have been identified in the genome, including 80 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. In addition, 18 genes possessed at least one intron. The phylogenetic analysis indicated that H. vulgaris was nested in Plantaginaceae with 100% bootstrap value and was a sister to Digitalis, Plantago, Hemiphragma, Veronica and Veronicastrum.
